Temperature protection of boiler water is one of the important measures to ensure the safety of boiler operation. It is necessary to provide multiple water temperature protection for each boiler to ensure that the boiler water temperature fluctuates within the normal range. The following are some water temperature protection measures.

1. Water temperature protection
       An outlet water temperature detecting sensor (thermal resistance or thermocouple) is arranged on the boiler outlet side to detect the water temperature in real time to ensure that the outlet water temperature does not exceed the rated value.

2. Secondary overheat protection
       In the boiler body design secondary heat-off protection, if it is detected that the furnace temperature exceeds the set value, immediately cut off the main power supply, prohibiting the boiler temperature from rising further.

3. Over temperature alarm parallel lock protection
       When the boiler temperature exceeds the limit value, the over-temperature alarm device is activated to prompt the furnace worker to troubleshoot the fault.

Precise water level control ensures that the boiler water maintains a dynamic balance, and multiple water level protection systems are used to ensure that the boiler water level fluctuates within the normal range to ensure safe operation of the boiler. In this small series, we will explain the water level control technology for the fast.

1. Electric contact type water level alarm protection The stainless steel self-sealing and short-circuit proof new electrode rod has a reliable self-sealing structure, which solves the technical problem that the domestic electrode rod often has false alarms. The new sealing material is combined with advanced technical transformation and self-sealing protective sleeve installation to protect the electrode rod from the water level.

2. direct reading water level protection Equipped with a two-color water level gauge, the water is red and white, easy to distinguish.

3. the built-in polar water level protection of the furnace body The water level change in the furnace can be directly detected at any time, effectively avoiding safety accidents caused by dry burning of the furnace body, and the work is very reliable.

For many users who want to open a bath, it is a headache to estimate how much boiler is needed based on the number of nozzles and the amount of water used. Below, we will take 100 nozzles and an average bath temperature of 40-60 °C as an example to answer your need for boiler equipment.

When calculating the boiler capacity, it is necessary to use 100 nozzles (the highest value) at the same time as the standard, and temporarily ignore how many people use at the same time, but use the number of nozzles as the estimation unit, as long as 100 nozzles are used at the same time.

An adult bathing water is about 0.2-0.3 tons per hour, and 100 nozzles use 20-30 tons per hour. Therefore, it is only necessary to satisfy a boiler that can supply hot water between 20-30 tons per hour. Considering the various factors such as the difference in bath water temperature, we estimate that 100 bathing nozzles will require a 2 ton bath boiler. If it is necessary to carry out the heating of the bath, it is necessary to calculate according to the actual heating area. You can tell our online customer service about your heating area and bathing nozzles, and the technician will give you a detailed analysis later.

At the same time, in addition to the boiler tonnage problem, there is a need to choose fuel. It is best to use fuel or gas boilers in the baths in towns. These two types of boilers are not only environmentally friendly but also well managed, and do not require special space for fuel storage. Also pay attention to the choice of water tank. Generally speaking, the boiler and water tank should select the maximum value, which can not only meet the needs, but also effectively avoid the boiler overload operation and prolong the service life of the equipment.

A 1 ton natural gas boiler consumes 75-80 cubic meters of natural gas per hour.

The gas consumption of a natural gas boiler can be calculated according to the following formula: gas consumption per hour of natural gas boiler = boiler thermal efficiency / natural gas calorific value / boiler efficiency. From the above formula, it can be concluded that the gas consumption of natural gas boilers mainly depends on boiler capacity, natural gas calorific value and boiler efficiency, while boiler capacity and natural gas calorific value are generally unchangeable, which can determine the amount of gas consumed per hour of natural gas boilers. It is the combustion efficiency of the boiler.

The combustion efficiency of a boiler generally depends on the quality of the boiler. Since its establishment, FANGKUAI Boiler has been studying natural gas boilers with many patented technologies. The boiler combustion efficiency can reach more than 107%. The fuel can be fully burned. The higher the boiler combustion efficiency, the lower the fuel input cost, which saves you. The fuel cost of the boiler is the best choice.

Steam ton is an engineering term referring to the boiler heating level, generally expressed in T/h, which represents the amount of steam produced per hour by this boiler.

In international units, megawatts (MW) is often used as the unit of thermal measurement, and the formula corresponding to steamed tons is: 1t/h=0.7MW=2.5GJ/h=6*10^6Kcal.

Usually we say that a 1 ton boiler does not mean that the weight of the boiler is one ton, but the amount of steam generated per hour by this boiler.

Note:

t/h: steamed tons / hour.

MW: MW, is a unit of power, which refers to the amount of electricity that a generator can emit per unit of time under rated conditions.

GJ/h: KJ/hour is the amount of heat exchanged per unit of time.

Kcal: A kilocalorie, also called a big card, is the amount of heat that 1 gram of water needs to raise 1 °C at 1 atmosphere.

The exhaust gas temperature of ordinary natural gas boilers is about 180 ℃. The higher the exhaust gas temperature, the lower the thermal efficiency of the boiler.

FANGKUAI Boiler's natural gas boilers are equipped with advanced condensing technology to condense high-temperature flue gas, release heat again, and the exhaust gas temperature is also reduced, which can be below 120 °C. From the perspective of energy saving and money saving, the use of condensing gas boilers can save about 30% energy compared to ordinary natural gas boilers.

At present, there is no national regulation on the exhaust gas temperature of natural gas boilers, but through the above explanation, you can know that the lower the exhaust gas temperature, the more fully the heat utilization in the flue gas, the higher the fuel utilization rate, the higher the thermal efficiency of the boilers, and finally achieve the goal of energy saving and money saving.

Inevitably, gas-fired hot water boilers will fail due to human error or boiler's own reasons in operation. After the failure, we should deal with it in time in order to prevent more damage. Fangkuai Boiler summarizes four repair methods after stopping and checking for your reference.

First, stop the furnace.
       1. Do not stop the pump immediately when the furnace is shut down. The pump must be stopped when the boiler outlet temperature is below 50 °C. At the same time, the water supply valve and the hot network return valve should be turned off, and the boiler water must be discharged before inspection and then repair can be carried out.

Second, check.
     1. Before entering the boiler, all the water in the boiler must be drained, and the sewage outlets are all open. The manhole on the drum, the hand hole on the header must be opened, so that the air can be convected for a period of time before entering the internal work.
       It must be noted that when someone inside the drum is working, there must be someone under the drum.
      2. Before entering the combustion chamber or flue to work, ventilation, anti-virus, fire prevention and explosion-proof measures must be taken. The flue gate connected with the main flue or other flue of running boilers will be closed tightly.
      3. Safety voltage should be used in lighting. If the boiler body and flue tubes are humid, the lighting voltage shall not exceed 12V. If it is dry, the lighting voltage should not exceed 36V. In addition, proper safety measures should be taken to prohibit the use of open-fire lighting.
