The present regulatory requirements enforce the modification of the firing modes of existing coal-fired utility boilers and the use of coals different from those originally designed for these boilers. The reduction in SO 2 and NO x emissions was the primary motivation for these changes.Get Price
Improvement in coal quality can'also lead to operating problems in a pulverized-coal-fired boiler. If a nonslagging coal is burned in a boiler designed for a slagging coal, furnace walls may be too clean, and too much radiant heat may be absorbed, which makes it difficult for the superheater to produce the necessary steam temperatures.Get Price
2. Process description of a coal-fired power plant A coal-fired power plant burns coal to produce electricity. In a typical coal-fired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler.

Boiler Operations That Affect Efficiency (Part 2) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production). However, these two goals often have opposing outcomes.Get Price
