  • Emissions and Efficiency Performance Of Industrial Coal

    Boiler Efficiency—Boiler efficiency improved by an average 1 percent when overfire air was increased on spreader stokers as a result of reduced carbon carryover. However, on mass-fired overfeed stokers, efficiency was reduced by an average 2.75 percent when overfire air was increased due to increased dry gas losses and increased bottom ash Learn More
