Exergy Analysis and Efficiency Improvement of a Coal Fired

Apr 17, 2013 · 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. The heat produced from the burning of the coal generates steam at high temperature and pressure.

1.1 Bituminous And Subbituminous Coal Combustion

firetube boilers used with coal are the horizontal return tubular (HRT), Scotch, vertical, and the firebox. Cast iron boilers are also sometimes available as coal-fired units in a handfed configuration. The HRT boilers are generally fired with gas or oil instead of coal. The boiler and furnace are contained in the same shell in a Scotch or

Modeling of SO3 formation and depletion processes in coal

Nov 15, 2020 · Theoretical model developed for the SO 3 formation and depletion processes in the region upstream of the economizer exit duct in coal-fired boilers. The model accounts for homogeneous conversion of SO 2 to SO 3 as a result of gas phase reactions, SO 3 catalytic formation due to Fe 2 O 3 in the fly ash both in suspension and as deposits on boiler tubes, and SO 3 depletion due to reaction with
