Title of the articleReduction of harmful emissions of nitrogen oxides in atmosphere by coppers at thermal power stations
Abstract.Problem statement. The purpose of the study is to optimize the regime parameters of boilers TG-104 of Surgut GRES-1 and reduce emissions of nitrogen oxides during the combustion of associated gas with the use of low-emission burners and flue gas recirculation, fed in an amount up to 8 % by smoke exhaust recirculation of dropping gas pipeline in the air mixer before burners. Composition associated gas in the experiments as follows: methane CH4 = 92,37 % (by volume), ethane = 4,74 % C2H6, C3H8 Propane = 0,77 %. We used direct swirl burner GMPV-50 in the amount of 12 pieces in one pot. Burners are located on the front of the combustion chamber wall in 2 tiers: the first tier below the level of 11.1 m, the second tier at around 14.1 m TG-104 boilers have an efficiency of one and a U-shaped arrangement of the heating surfaces.The wall of the furnace fully shielded by tubes of outer diameter 60 mm and a wall thickness of 6 mm, made of steel 20 in steps of 64 mm. Under the furnace rear screen panel is formed, it is inclined to the horizontal 15 °, and also protected from the flame radiation layer of refractory brickwork. Results. Essential reduction surge oxides of the nitrogen is received under small steam load. With growing of the load share recirculation decreased because of need of the maintenance of the high temperature of the secondary overheat pair. This brought about strong growth surge oxides of the nitrogen because of increasing of the temperature of the torchlight in zone of the combustion fuel. Conclusions. It was found that the effect of changes excess air ratio in the formation of nitrogen oxides with increasing load is insignificant. The effect of increased axial and circumferential inner air twists in burners to reduce the formation of nitrogen oxides is shown for all values of boiler load.
Keywords.nitrogen oxides, fuel burning, heat of combustion, temperature, copper, coefficient of efficiency, coefficient of air excess, leaving gases, emissions.
