How to Run a Coal Fired Boiler at the Best Efficiency

Boiler furnace design will depend more on fuel characteristics, and further heat transfer surface sizing will depend on furnace outlet temperature. Furnace Size Varies for Gas, Oil and Coal Firing - Furnace sizing is a very important for a successful boiler design. The variation in boiler furnace size can upset the performance drastically. Oil and gas fired units have more uniform sizes, but the coal fired units have large variation.

Slagging and Fouling in Coal Fired Boilers - Bright Hub

Coal fired boilers experience deposition and slagging depending upon the ash characteristics of ash in the coal being fired. In many cases the operating parameters also play a major role. The molten or partial melting pasty ash deposits in radiant heat transfer surface like boiler furnace is termed as slagging. The sintered ash deposit in the convection region in boiler is called fouling. Coal

The History of the Steam-Generating Boiler and Industry

They were the first to patent their boiler design, which used tubes inside a firebrick-walled structure to generate steam, in 1867, and they formed Babcock & Wilcox Company in New York City in 1891. Their first boilers were quite small, used lump coal, fired by hand, and operated at a very low rate of heat input.
