Pressure Classification:
Low-Pressure Steam Boiler: Operating pressure is generally between 0.1 and 1.6 MPa.
Medium-Pressure Steam Boiler: Operating pressure is generally between 1.6 and 4 MPa.
High-Pressure Steam Boiler: Operating pressure is generally above 4 MPa.
Classification by Heat Conversion Method:
Fire-tube Steam Boiler: High-temperature flue gas generated by combustion passes through water pipes, converting water into steam.
Water-tube Steam Boiler: Water in the water pipes is heated and converted into steam, with flue gas flowing around the water pipes.
Fuel Classification:
Gas-fired Steam Boiler: Uses coal as the primary fuel.
Gas-fired Steam Boiler: Uses natural gas fuels such as natural gas and liquefied petroleum gas (LPG).
Oil-fired Steam Boiler: Uses liquid fuels such as diesel and heavy oil.
Biomass Steam Boiler: Uses biomass fuels such as sawdust, firewood, and waste. 4.4 Application Classification:
Power Industry Steam Boilers: Used in power plants for steam generators, producing high-temperature, high-pressure steam to drive steam turbine generators.
Chemical Industry Steam Boilers: Used for heating, reaction, and cooking in chemical processes, providing heat.
Textile, Paper, and Food Industries Steam Boilers: Used for heating, cooking, and dry heat in production processes.
Petroleum and Natural Gas Industries Steam Boilers: Used for heating and distillation in petroleum and natural gas extraction and processing.
As an important energy equipment, steam boilers will continue to innovate and develop in areas such as efficient energy utilization, clean environment, intelligent management, and energy system formation, making a greater contribution to sustainable development.
