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. In contrast, a stoker-fired boiler emits only 3.0
