  • Automatic Coal- Fired Boiler – Providing heat when you

    Temperature inside boiler (furnace) is around 1100 deg to 1200 deg. Although it is favorable to keep it under 1100 deg or otherwise ash in flue gas will melt as forming clinkers and it will stick to to boiler walls. I am talking about big boilers of 800MW (super critical) capacity. Output main steam temperature ranges from 550 to 570 deg.Learn More

  • Combustion Air Pre-Heater | CleanBoiler.org

    Combustion air pre-heater technology on large coal-fired boilers dates back to the early 1900's, and is used on most all large boilers todays.

  • Pulverized coal-fired boiler - Wikipedia

    A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.Learn More
