Answer the classification of boilers first:
1. According to the flue gas flow in the boiler: water tube boiler, shell boiler (fire tube boiler), water and fire tube combined boiler
2. Depending on how the drum is placed: vertical boiler, horizontal boiler
3. Depending on the destination: domestic boiler, industrial boiler, power plant boiler, vehicle and ship boiler< /p>
4. Depending on the support: steam boiler, hot water boiler, steam and water boiler, organic heat transfer boiler
5. According to the installation method: quick installation boiler, assembled boiler. , bulk boiler
p>6. Depending on the fuel: coal boilers, oil boilers, gas boilers, heat recovery boilers, electric boilers, biomass boilers
7. According to water circulation: natural circulation, forced circulation, Mixed cycle
8. Depending on the pressure: normal pressure boiler, low pressure boiler, medium pressure boiler, high pressure boiler, ultra high pressure boiler
9. Depending on the number of boilers: single drum boiler, double drum boiler
10. Depending on the combustion inside or outside the boiler: internal combustion boiler, external combustion boiler
11. According to the flow mode of the working fluid in the evaporation system, it can be divided into natural circulation boiler, forced circulation boiler, once-through boiler, etc.
12. Classification according to manufacturing level: Class A, Class B, Class C, Class D, Class E (divided according to manufacturing boiler pressure)
13. depending on the steam outlet pressure. These are: low pressure boiler (P<2.5MPa), medium pressure boiler (22.5 Different boilers have different functions. Their basically the same function is that the boiler boils water to produce steam at high temperature and high pressure in order to utilize the steam. The power plant water supply system is divided into different functions: Circulating water system - cooling of condensers and various chillers. Domestic firefighting water system ---- domestic water and firefighting. Industrial water system ----cooling of rotating machine bearings. Deionized Water System: The working fluid used by boilers to generate steam. That's all. I won't talk about small systems.
