The burner can be said to be a very important auxiliary equipment in the oil-fired boiler. The quality of the burner can also affect the operation of the boiler and the discharge of pollutants. When equipping an oil-fired boiler with a burner, pay attention to purchasing a burner with a suitable model and capacity to avoid waste of resources caused by the mismatch between the burner and the boiler.

If the oil-fired boiler burns diesel, there are certain requirements when choosing a burner. It is necessary to achieve low energy consumption and small smoke emission, and to avoid the problem of polluting the atmosphere. If one of these points cannot be reached, some processing can be used to achieve the goal. However, at least the quality of the burner should be qualified, and good quality products should be used.

If it is a boiler with a relatively small tonnage, it is a matter of concern for many users to use electricity and oil fuel to save money. Small boilers can use both electricity and oil as fuel energy. However, when comparing the two in terms of consumption, it is still less oil than electricity (in the absence of electricity subsidies); and oil Similar fuels are widely distributed in China, and it is not troublesome to call them.

For a 1 ton oil-fired boiler, if it burns standard diesel, then the boiler's fuel consumption per hour can be calculated to be 65KG. And, the larger the boiler tonnage, the higher the combustion efficiency. This type of boiler is a type of boiler that is often used. In the choice of fuel, it can be light oil or heavy oil.

No matter how intelligent the boiler equipment is, it still needs the boiler operator to operate and maintain the boiler. Only some highly automated boilers only need one boiler worker, but if the boiler is not highly automated, it is necessary. Many furnace workers jointly manage, which will inevitably lead to an increase in labor costs. The boiler intelligence level of Zhengzhou Fangkui Boiler Factory is very high. Generally, only 1-2 boiler workers are required to complete the boiler maintenance and daily operation and maintenance work.

Do boiler operators have different working ranges for different grades?

According to the standard of "Boiler Safety Managers and Operators Assessment Outline", the regulations for boiler operators are divided into three levels of I, II, and III, and each A level of work scope. So, on this question, the answer is yes, and this is no doubt.

Does the boiler's scheduled water belong to boiler water or boiler feedwater?

The boiler's scheduled water belongs to the boiler water, not to the boiler feedwater, and it must be clear to us, so it cannot be sloppy.

What certificate do boiler workers need? How long can it be obtained?

The boiler operator who operates the boiler needs the certificate of the boiler, otherwise he cannot be employed. As for the acquisition method and time, generally speaking, it can be obtained within one week or one month.

At present, centralized heating is the preferred method of heating in most cities and regions. Compared with decentralized heating, it is more convenient and better controlled. The hot water boiler is the main heat energy equipment for central heating. Zhengzhou Fangkui Boiler Factory will come to briefly talk about this type of hot water boiler.

In central heating, if a gas-fired hot water boiler is used, how to select and quote?

In central heating, if a gas-fired hot water boiler is used, the type selection mainly depends on the heating area, and the specific type and specifications of the boiler are determined by the size of the heating area, so that the wrong selection can also be avoided. The quotation of this type of boiler is based on the tonnage of the boiler.

What is the 5 tons of 5 tons hot water boiler? And can the sewage outlet on the hot water boiler be omitted?

For a 5 ton hot water boiler, 5 ton refers to the thermal power of the boiler. If converted, it is equivalent to 3.5 MW. The sewage outlet on the hot water boiler must be connected, and there must be no omissions. Moreover, the location of the sewage is also different and cannot be treated uniformly.

The boiler model, which is expressed as WNS4.2-1.0/115/70-Q, what does it say?

If the boiler model is expressed as WNS4.2-1.0/115/70-Q, it means that this is a horizontal hot water boiler, because W refers to horizontal, N refers to internal combustion, and S refers to the room Burning. In addition, it can also be known that the heating capacity of the boiler is 4.2MW per hour, which is equivalent to 6 tons, and its rated pressure is 1MPa. In addition, the outlet and return water temperatures are 115°C and 70°C, respectively. Fuel is natural gas, liquefied gas, city gas and other gas fuels.

Coal-fired boilers account for half of the number of boilers used in my country, while gas-fired boilers are a rising star in recent years. These two types of boilers have their own advantages and disadvantages. Let's talk about the technical experts of Zhengzhou Fangkui Boiler in terms of performance comparison.

What are the obvious differences between coal-fired and gas-fired boilers?

For coal-fired and gas-fired boilers, if these two common types of boilers are compared, the differences between them are mainly:

Difference one: Coal-fired boilers require coal ash storage sites, while gas-fired boilers do not, because the fuel is gas.

Difference 2: When the coal-fired and gas-fired boilers work normally, their water consumption is almost the same. However, the gas-fired boilers can save on auxiliary water for dust removal and slag removal.

In the gas-fired boiler room, are there any regulations on the number of furnace workers? In addition, how should the comparison be made?

There is no specific requirement on the number of furnace workers in the boiler room of gas boilers. Moreover, this type of boiler can have a high degree of automation, so it can be managed in a unified manner. Therefore, only one furnace worker is required. As for the comparison between gas-fired boilers and other boilers, a comparable standard is required, that is, only two or more types of boilers can be compared before a conclusion can be drawn.

For a gas-fired boiler, if it produces 8.6 tons of hot water, how much natural gas can be saved by raising the boiler feed water temperature by one degree? On a gas boiler, if it is 1 ton of water, then the heat required to raise the temperature by one degree is 1000 kcal, and at this time, the gas consumption can be reduced. If the calorific value of natural gas is 8600 kcal, then for the above problem, the conclusion that can be obtained by calculation is that for every 8.6 tons of hot water produced, the amount of natural gas can be saved is 1 cubic meter.

Industrial boilers can provide a large amount of power output for users in the broad industrial field, but it will also be accompanied by a certain degree of danger. Therefore, when operating and using industrial boilers, certain safety regulations must be followed. In particular, the boiler operator who operates the boiler must have certain professional skills.

The heating value of a 10-ton boiler is equivalent to 6 million kcal. Therefore, if the calorific value of natural gas is calculated according to 8600 calories, then the amount of natural gas consumed per hour is about 700 cubic meters. Different boilers have different auxiliary machines.

In boiler equipment, if the different furnace types are different, then the ratio of fly ash to slag is different, so the answer to question 1 is different. For example, for a pulverized coal furnace, the proportion of fly ash is 90% and the proportion of slag is 10%. The boiler supervisor and boiler water tester must be certified to work, and must not violate this requirement.

In the waste heat boiler, if it is medium-pressure steam, the pressure is 0.93MPa and the temperature is 280°C; if it is low-pressure steam, the pressure is 0.7MPa and the temperature is 260°C. If the temperature of the condensate is too high, it needs to be cooled and treated before entering the boiler.

Electric hot water boilers are now relatively hot boiler equipment, especially at atmospheric pressure, which is safer to use and has no environmental problems. Today, Zhengzhou Fangkuai Boiler Factory will come to briefly talk about what type of boiler equipment the electric hot water boiler is.

Electric hot water boiler, also known as electric heating boiler, electric heating boiler, electric heating boiler, electric bath boiler, and electric bath boiler; this type of boiler uses electric heating technology and control system to produce hot water in order to meet heating or heating demand.

There are several methods for descaling an electric hot water boiler.

If the use of caustic soda, that is, sodium hydroxide, then heating and pressurizing, and to maintain a certain period of time before the waste water can be discharged.

Moreover, on different specifications of electric hot water boilers, the time required for descaling is different, for small boilers it is 24 hours, for large boilers it is more than 36 hours.

The circulating pump in a pressurized hot water boiler generally uses the control cabinet on the boiler, without the need to use a separate control cabinet unless there are special requirements. The 6-ton hot water boiler has a heat production of 1.8 million Kcal/H. However, this is a theoretical value, in actual work, there may be deviations. Therefore, everyone should pay attention.

A steam boiler is a device that outputs high-temperature steam. Regarding the relevant parameters of steam output, users should pay attention to two aspects: one is the rated evaporation, but it will leave a certain margin in the design of the boiler, generally It is 10% to 15%, or 20%. The second is the upper limit of the output, which has a certain relationship with the rated evaporation, but it is not equivalent.

What are the specific requirements for water level protection devices on steam boilers?

On steam boilers, the specific requirements for its water level protection device are: for steam boilers with a rated evaporation capacity of not less than 2t/h, high and low water level alarm devices and low water level interlock protection devices shall be provided. The steam boiler with a rated evaporation capacity of not less than 6t/h, in addition to these two, should also have a steam overpressure alarm and interlock protection device, which are indispensable.

Is there a stipulated requirement for the exhaust temperature of a steam boiler with a rated evaporation capacity of not less than 1t/h? In addition, what is the price of auxiliary equipment for this boiler? For a steam boiler with a rated evaporation capacity of not less than 1t/h, the exhaust temperature of the boiler must not exceed 170°C, and this must be strictly implemented. The basis is TSG G0002-2010.

The auxiliary equipment of the steam boiler is generally in the range of dozens to hundreds of thousands in terms of price. Specifically, it depends on the use requirements, specifications, and the number of uses. Moreover, its configuration is also divided into high-end and low-end.

Enterprises that need to use boilers are more cautious when facing boiler selection, because this relates to the company's operational investment costs for boilers and later safety use issues. Song Gong, a technical engineer of Zhengzhou Fangkuai Boiler Factory, will come to talk about what factors should be considered when selecting a boiler.

Aspect 1: How much steam is needed by the enterprise itself, or the heat supply of hot water.

Aspect 2: Different boilers, their important and related parameters, and analysis of their selection relationship.

What is meant by low temperature, low pressure, medium temperature, medium pressure, and high temperature and high pressure in the generator set? In addition, what do you mean by adding medicine in the pot?

The low temperature, low pressure, medium temperature, medium pressure, and high temperature and high pressure in the generator set can be either boiler parameters or steam turbine inlet parameters. Therefore, it can have two meanings. As for the medicinal treatment in the pot, specifically, it is used as supplementary treatment for boiler make-up water, condensate water and generated return water treatment, and does not refer to other treatments.

For boilers, are they different in terms of service life and specifications?

Boilers have different sizes, so their service life is also different. Specifically, it is: small boilers, which are generally used for 6 to 10 years; for large boilers, it is not necessarily, depending on the specific use, because it is determined by it. Therefore, on this question, the answer is yes. That is, the service life of boilers with different specifications is different.

For enterprise units, the boiler may not need to be used 365 days a year. When the construction period is stopped, the boiler is no longer needed, so the boiler needs to be shut down. What materials should be prepared when the boiler is shut down? To which organs should you report to? Specifically, listen to the boiler experts of Zhengzhou Fangkui Boiler Company to explain to you.

What report should be submitted to the Boiler Inspection Office when the boiler is shut down?

If the boiler is shut down, it is necessary to submit a "Boiler Deactivation Report" to the Boiler Inspection Office. Its main purpose is to be used as an annual inspection type of the boiler, which can be used to prove that it is not in use. Inspection fees, and safety valve verification fees, etc.

In addition, the specific content of the "Boiler Decommissioning Report" mainly includes the company name, boiler number, boiler use registration number, boiler model, number and use, etc. In addition, the reasons for stopping the furnace and the safety protection measures when the boiler is stopped are also indispensable.

The inspection process before the hot water boiler starts, specifically speaking, there are the following steps.

Step one: Check whether the safety accessories, thermal instruments and electrical instruments in the boiler are complete and intact, and can work normally.

Step 2: Check the connections, welds and pipelines of the hot water boiler for water leakage and other phenomena.

Step 3: Check whether the sewage line, inlet line and return line are unblocked.

Step 4: Fill the expansion and replenishment tank with water, and check the line voltage to see if its voltage is 380V. If there is a dial, whether it is controlled within 5%.

Step 5: Open the manual valve, as well as the water supply and return valves. After that, start the pump and burner, and check whether they are operating normally.

Step 6: Perform water filling operation on the boiler heating system in order to exhaust the air in the system without any residue. What are the specific inspection procedures in the operation of gas hot water boilers?

Gas hot water boiler is a type of hot water boiler. The inspection process in operation mainly includes the following points:

Process 1: Check the outlet and return water temperature of the gas hot water boiler, whether it is within the normal range. And, whether the pressure of the boiler is normal and stable, and whether its combustion condition is good.

Process 2: Check the make-up water pump and backup water pump, mainly to see whether it is running normally. And, to check the boiler water quality, whether it meets the specified standards in specific parameters. In addition, sewage should be carried out every day to remove scale in the boiler.

Hot water boilers are indispensable thermal energy equipment in the field of heating and heating. There are also many matters that require special attention regarding the operation of hot water boilers. Zhengzhou Fangkuai Boiler Factory will come to answer them one by one.

What are the specific requirements for the feed water hardness of hot water boilers?

The requirements for the hardness of feed water for boilers such as hot water boilers are less than 0.6 mmol/liter. However, in order to avoid the problem of boiler fouling, which affects the boiler efficiency, it is carried out with reference to the steam boiler feed water standard to achieve the above purpose, because the feed water hardness of the steam boiler is required to be less than 0.03mmol/L, relative Strictly speaking.

The model of electric hot water boiler is WDR-95/70, so how should it be understood?

The electric hot water boiler is one of the hot water boilers, which uses electric energy to burn the boiler, and then, converts energy to achieve the purpose of use. And its model indicates that it is WDR-95/70, then its correct understanding is:

The preceding letter is the abbreviation of the model of the electric hot water boiler, and the following number 95/70 refers to the boiler's outlet and return water temperature in degrees Celsius.

Does the burner in the hot water boiler have a specific model? Can it be used universally?

There are many types of burners on hot water boilers, such as light oil burners, alcohol oil burners, heavy oil burners, natural gas burners, and biological particle burners. Therefore, there are different types and specifications of hot water boilers, which are not universal.

Most gas boilers are under certain pressure, so there will be certain safety risks during use. Regarding the operating pressure of gas boilers, what are the matters that users need to pay attention to? Let Zhengzhou Fangkuai boiler tell you the answer.

In gas-fired boilers, if natural gas is used as the fuel, the system pressure of the boiler is in the range of 10-20kPa, which can avoid various problems during the use of the gas-fired boiler.

Is the amount of natural gas required per hour for a 2-ton gas-fired boiler different from that of a different boiler manufacturer? The amount of natural gas required per hour for a 2 ton gas-fired boiler can be said to be different for different boiler manufacturers. It cannot be exactly the same. Therefore, the answer to this question is yes. However, it has an approximate range of 150-160 cubic meters per hour.

Is the 25-ton gas boiler a uniform price?

There are many specific types of 25-ton gas boilers, such as gas hot water boilers and gas steam boilers. Therefore, there are different prices for different specific types. Therefore, it cannot be a uniform price. Moreover, for the purchaser, it is necessary to consult their manufacturer and inform the heating plan, etc. before the manufacturer can give a specific price, that is, to perform the product quotation.
