Pulverized Coal Boiler

A typical pulverized coal boiler consists of (1) the furnace, which is the lower boiler part, where the burners and the firing system are installed and where the combustion takes place and (2) the convective section, where the convective heat exchanger surfaces are installed. The boiler membrane walls have usually the function of the boiler evaporator.

CycloneFurnace Boilers

CycloneFurnace Boilers. BW developed Cyclone furnace technology to burn coal grades that are not wellsuited for pulverized coal combustion. The ash from these coals has a very low melting temperature. This molten ash would normally be deposited on all downstream heat transfer surfaces, causing severe slagging and fouling with resultant ...

Pulverized Coal Pipe Testing and Balancing

Pulverized Coal Pipe Testing and Balancing By Richard F. (Dick) Storm, PE The first step in optimizing combustion system performance is balancing the air and fuel flowing through each of the plant's coal pipes—the pipes that convey the air/fuel mix from the pulverizers to the individual burners in the furnace wall. Also necessary is information on the properties of the coal traveling through ...
