Abstract

Results of complex tests of the TGMP-314 boiler of thermal power plant-23 of the Mosenergo Company operating on natural gas and furnace oil after design improvement are presented. Toxic emissions of nitrogen oxides were diminished by the use of low-toxicity burners, supply of air to secondary blow nozzles, and introduction of recirculating gases into the burner channels. These measures lowered the emissions of NOx, benz(a)pyrene, and other harmful substances into the atmosphere below the standardized values. The boiler proved to operate reliably in the entire range of tested loads in the gas- and oil-fired modes with stage firing and recirculation of flue gases. The rated parameters of live steam and reheat steam were steadily maintained.
