Some users who purchase boilers are not very good at boiler installation and commissioning, and often hope that the boiler manufacturer can directly be responsible for the transportation, installation and commissioning of the boiler. So, can the boiler manufacturer be responsible for installing the boiler? Let Zhengzhou Fangkuai Boiler Factory answer for you.

1. Boiler manufacturing enterprises can install boilers. Because according to the "Regulations for the Supervision and Management of Boiler Installation and Renovation Units" Boiler manufacturing enterprises that have obtained the boiler manufacturing license can transform the boilers manufactured by the enterprise and install the whole (assembled) factory-made boilers manufactured by the enterprise without obtaining a separate license.

2. The boiler is a kind of energy conversion equipment. The energy input to the boiler is chemical energy and electric energy in the fuel, and the boiler outputs steam, high temperature water or organic heat carrier with certain thermal energy. The original meaning of pot refers to a water container heated on a fire, and a furnace refers to a place where fuel is burned. A boiler includes two parts: a pot and a furnace. The hot water or steam produced in the boiler can directly provide the required heat energy for industrial production and people's lives, and can also be converted into mechanical energy by a steam power device, or converted into electrical energy by a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, but there are also a few applications in industrial production. The boiler that produces steam is called a steam boiler, often abbreviated as a boiler, and is mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.

3. The boiler is carried out in two parts of "boiler" and "furnace" at the same time. After the water enters the boiler, the heating surface of the boiler in the steam-water system transfers the absorbed heat to the water, so that the water is heated into hot water with a certain temperature and pressure or steam. Be led to the application. In the combustion equipment part, the combustion of fuel continuously releases heat, and the high-temperature flue gas generated by the combustion transfers the heat to the heating surface of the boiler through the heat transmission, and the temperature of itself is gradually reduced, and finally discharged by the chimney.

For users who need to use a vacuum hot water boiler, the selection of the boiler is a very critical step, which is related to the use and maintenance of the boiler in the later period. If you buy inappropriate boiler equipment, you will not only need to purchase a second time. This leads to increased input costs and delays the project construction period. So, what issues should be paid attention to when selecting a vacuum hot water boiler? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.

1. Fuel selection for vacuum hot water boiler:
       Fuels such as natural gas and liquefied petroleum gas are common fuels used in vacuum hot water boilers. Zhengzhou Fangkuai Boiler Factory recommends that users give priority to natural gas and regenerated oil, which can be used for both petroleum and natural gas (special order).

This data has a great relationship with building insulation and indoor use, but it has a small relationship with the building area. relationship.

3. For the pressure selection of the vacuum hot water boiler:
       If you want the vacuum hot water boiler to output warm water and sanitary hot water, the pressure of the boiler is 0.8 MPa, and the pressure of the parts is 0.81~1.2 MPa, and the parts are recommended to use high-pressure devices. If the pressure is 1.21 ~ 1.6 MPa, the fragmented and comprehensive element should be based on economic and technical analysis to use the ultra-high pressure unit type, or stop the secondary heat exchange. If the pressure is above 1.6MPa, it is recommended to design two heat exchangers for the vacuum hot water boiler.

4. For the location selection of the vacuum hot water boiler:
       The unit of the vacuum hot water boiler runs smoothly, with almost no vibration and low music. The location of the machine room is very convenient. The basement, air, floor, and roof can be used as a machine room. If it is used in a high-rise building, in order to reduce the unit pressure, the boiler room should be set in the middle or the top of the floor.

1. Before each operation of the vacuum hot water boiler, the gas pressure of the boiler must be checked to ensure that its pressure is normal. If the static pressure is only 6 kPa, it should be noted that only a small fire can be maintained, because at a pressure of 6 kPa, the boiler running on a large fire may cause flameout due to insufficient pressure.

2. When using a vacuum hot water boiler, pay attention to the pressure and temperature of the domestic hot water and heating medium water, and make sure that the pipeline valve is opened to prevent the inlet and outlet water valves of any heat transfer branch from closing, because during use, due to thermal expansion And the principle of cold shrinkage, the pressure will far exceed the rated working range. This caused major accidents such as pipeline explosions and boiler scrap.

3. Under various normal working conditions of the vacuum hot water boiler, pay attention to the operation of the water pump, carefully observe the outlet pressure of the water pump and its sound, and turn on the boiler control power supply when it works normally.

4. When the vacuum hot water boiler is in operation, pay attention to setting the relevant parameters on the display screen to ensure that the middle water temperature, the outlet water control temperature, the flame conversion temperature and the temperature difference can meet the operating requirements.
