  • 1.2 Anthracite Coal Combustion

    A second type of stoker boiler used to burn anthracite coal is the underfeed stoker. Various types of underfeed stokers are used in industrial boiler applications but the most common for anthracite coal firing is the single-retort side-dump stoker with stationary grates. In this unit, coal is fed intermittently to the fuel bed by a ram.Learn More

  • Coal-Fired Industrial Boiler Inspection Guide

    Tangential or corner-fired pulverized-coal-fired boilers tend to pro- duce less NO than wall-fired units. s The particulate emission rate is a function of the coal ash content and the firing method. Pulverized-coal-fired boilers emit between 70 and 85 percent of the ash in the coal as fly ash.Learn More

  • A Coal-Fired Thermoelectric Power Plant - USGS

    Dec 31, 2018 · A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler…Learn More
