  • Numerical Simulation of Coal Combustion in a Tangential

    Apr 08, 2021 · High gas temperatures inside the boiler may also lead to slagging and fouling problems, which adversely affect the heat transfer to the steam side. One of the principal ways of finding a compromise in tangentially fired pulverized coal (PC) boilers, which constitute the majority of the utility boilers, is through tilting the burners.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.
