  • Liquefied petroleum gas steam boilers (LPG Steam Boilers):Use liquefied petroleum gas as fuel and are suitable for situations where there is sufficient supply of liquefied petroleum gas in the area.

1.6 Oil-Fired Steam Boilers

  • Light Oil Steam Boilers:Use light oil as fuel.
  • Heavy Oil Steam Boilers: Use heavy oil as fuel.

1.7 Solid Fuel Boilers

  • Coal Steam Boilers: Use coal as the main fuel.
  • Biomass Steam Boilers:Use biomass such as wood and waste plants as fuel.

1.8 Multi-fuel Steam Boilers

Coal-Biomass Co-Firing Boilers: Able to adapt a variety of fuels, including coal and biomass. 

1.9 Condensing Boilers

Condensing Natural Gas Steam Boilers: Use the heat in the flue gas to improve the overall efficiency of the boiler.

These types of steam boilers vary in design and application, and companies typically consider factors such as their production needs, energy supply, environmental impact, and efficiency when selecting one.
