  • An overview of problems and solutions for components

    Dec 21, 2017 · In Atmospheric Fluidized Bed Combustion Boiler (AFBC), crushed coal of size 1–10 mm is supplied to the fluidization media. As the temperature of furnace becomes equal to the ignition temperature of the coal it starts burning. Coal supply is also controlled so that the temperature of the fluidized bed can be kept between 750 and 850 °C.Learn More

  • Natural Gas Fired Boilers

    Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal Learn More
