ABSTRACT
Pulverized coal combustion is one of the typical entrained-bed combustion materials. Pulverized coal combustion is the most common method, because the combustion efficiency is higher than in the other systems and it is easy to scale up. This chapter reviews the pulverized coal combustion system as an example of combustion of solid fuels. As the combustion profile of solid fuel is affected by fuel property, the combustion condition is controlled according with fuel property. For example, low carbonized coal includes high content moisture and it becomes fine particles on combustion, so the injection velocity of coal particle from the burner and swirl vane angle of secondary air are reduced for low carbonized coal. The secondary air and the tertiary air are provided into the furnace from the outer region of the primary air port. The furnace is classified into the front-firing type, the opposed-firing type, and the corner-firing type.
