Circulating Fluidized Bed (CFB) Boilers

The liquid electrolytes forms wet spots on the surfaces, causing general corrosion and material loss in the form of pitting. In waste-to-energy plants, dew point corrosion is less common than in coal-fired plants, because SO3 reacts with chlorine species, making the formation of sulfuric acid less likely.

2015-3-12 · With coal firing: Loss occurs as grit carry-over or carbon-in-ash (2% loss). Example :In chain grate stokers, large lumps will not burn out completely, while small pieces and fines may block the air passage, thus causing poor air distribution. Increase in the fines in pulverized coal also increases carbon loss.

This situation results in a loss of efficiency because not all of the potential energy of the coal is captured in the combustion process resulting in fuel wastes. Combustion processes that run fuel rich are "running dirty" meaning an increase in pollutant emissions.
