• Pulverized Fuel Fired Boilers Introduction ESN

    Pulverized fuel boiler is the most commonly used methods in thermal power plants and is based on many decades of experience. To know The coal is ground (pulverized) to a fine powder in the coal mills so that less than 2 per cent is +300 micro metre (μm) and 7075 per cent is below 75 microns, for bituminous coal.

  • Drax Power Station, Cleanest And Most Efficient CoalFired Power

    Drax Power commissioned a 'direct injection' system on one of its six generating units. 'Direct injection' allows biomass materials to be injected either directly into the boiler or into the fuel line, which delivers a mixture of pulverised coal and hot air into the boiler. This bypasses the pulverising fuel mills, potentially allowing
