Abstract Measurements made of the Krasnoyarsk energy systems showed that nitrogen oxide concentration on combustion of Kansko-Achinsk basin coal in solid-bottom furnaces is slightly less than in boilers of the same capacity during combustion of Ekibastuz, Donbas, and Juznetsk coal. Special studies were conducted to clarify a possible reduction in nitrogen oxide blow-out. It is concluded that recirculation of 15% of flue gases through the burners does not affect significantly the nitrogen oxide blow-out level on Kansko-Achinsk combination coal in a solid-bottom furnace (with a maximum temperature range in the combustion core of 1300 to 1400/sup 0/C); the nitrogen content in initial fuel and the excess air ratio in the operating burners are the main factors determining nitrogen oxide concentration in flue gases; and nonstoichiometric combustion of coal consisting in reduction in the excess air ratio to the lower burner stage with corresponding increase in the excess air ratio to the upper stage, makes it possible to reduce the nitrogen oxide blow-out by 15% approximately.
