A Method of Reducing the SO2 Emission from Power Boilers ...
The process consists in introducing a lime or dolomite sorbent into the boilers combustion zone. Chemical reduction occurs at the temperature of 9001000°C that lets reduce the SO 2 concentration by ca. 35%. After leaving the boiler and passing through a rotational air-heater the combustion gas enters a reactor which is a special-purpose variation of the boiler flues vertical segment.
The generation process of fuel pyrolysis gas from wood and other solid fuels in high temperatures within the range of 200-800 Zero in conditions of oxygen deficiency and the subsequent afterburning of the released gas which is mixed with preheated secondary air in the afterburner chamber. In the process of pyrolysis gases at the outlet of the boiler mainly contain carbon dioxide and water vapor the amount

emissions from coal-fired power plant boiler furnaces. Sulfur dioxide SO2 emissions from coal-fired furnaces whose construction began after August 17 1971 must by Environmental Protection Agency (EPA) regulation contain less than 1.2 lbm SO2 per 106 Btu (heating value of fuel fed to the boiler). When coal containing a

Feed water is pumped into the boilers and is converted to superheated steam which is taken to a conventional 660 MW (e) steam turbine-generator. The energy in the steam is converted to electricity in the turbine-generator which is supplied to the National
