The basic sources of allocation of polluting substances in an atmosphere on Starobeshevskaya TPP are boilers. Under certain conditions there is a local increase of pollution of a ground layer of an atmosphere in the zones removed on significant distances as a result of long-distance carries of emissions. In products of combustion of organic fuel Starobeshevskaya TPP priority emissions of atmospheric air are oksid sulfur, nitrogen, carbon, vanadium, firm particles - a dust inorganic with contents SiO2 - 20-70 %. So emissions make: - oksid nitrogen 27 719,3 t/year; - oksid sulfur 206 001 t/year; - A dust inorganic with contents SiO2 - 20-70 % 186 819,1 t/year. At reconstruction of a thermal power station replacement of existing boilers by more modern, with a circulating boiling layer is planned. Decrease reduction of concentration of emissions oksid sulfur in an atmosphere is achieved by controllable addition in топку limestone which amount is supervised in a separate contour of management. In view of the contents of water and ashes the parameter of the contents of sulfur makes approximately 1,5 % in the mixed fuel. More the high level of concentration of emissions CO in an atmosphere of boiler ATSKS in comparison with the boiler with torch burning fuel is caused by low temperature of burning of fuel. Decrease of concentration of emissions CO in an atmosphere probably: - At increase of temperature, that inevitably conducts to increase of concentration of emissions NOX and SO2 with additional consumption of limestone; - Due to submission of additional air, that in turn conducts to the additional charge of fuel (to increase of a stream of ashes and increase of concentration CO). Value of concentration of emissions CO in an atmosphere from boiler ATSKS equal 250 mg/nm3 is the conciliatory proposal as thus values of concentration of emissions NOX and SO2 are minimal. | |
