The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and

MODIFYING an existing coal-fired boiler to natural gas firing capability, either to replace or to supplement coal as the primary fuel source, is an extensive – and expensive – project. Although each project is different, the scope of the

TE emission behaviors in coal-fired power plants have been reported extensively, while those in coal-feed industrial furnaces are limited. In this chapter, the emission characteristics of TEs in coal-fired industrial boilers, including layer-burning boilers, chain-grate boilers, circulating fluidized-bed boilers cement kilns, and iron and steel production processes are summarized.
