Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels. Coal is ground to the size of a fine grain into the boiler, mixed with air and burned in the flue gas flow. Biomass and other materials can

Paper of the Year A Case Study on Coal to Natural Gas Fuel

Since natural gas has only trace amounts of ash, slagging and fouling would not occur. This lack of slagging and fouling may have a hidden risk of leading to more heat transfer problems in the boiler; coal-fired boilers are designed with a default assumption of a certain amount of slag and reflective ash coating their surfaces.
