RESULTS OF COAL RESEARCH TO REDUCE POLLUTANT EMISSIONS

Abstract

When solid fuels are burned, polluting toxic chemicals are released into the environment as part of the flue gases. The most common toxic substances polluting the atmosphere, are carbon monoxide CO, sulfur dioxide SO2, nitrogen oxides NO2, hydrocarbons СnHm and dust. The calorific value and chemical composition of solid fuels of the Sary Monol deposit of Alai and Muz-bulak deposits of Uzgen districts, Osh region of Kyrgyzstan were studied. Currently, the Osh Ak-Tash OJSC enterprise uses coal from the Sary Monol deposit in the Alai region for brick firing. It is recommended to use Muz-Bulak coal from the Uzgen region for firing bricks (which has an ash content in working condition of 7.37%, an ash content in a dry state of 7.52%, a lower calorific value of 30860 Qir, kJ / kg 7370 kcal / kg, sulfur content S - 0%). When switching to the use of coal from the Muz-Bulak deposit in the Uzgen district, the enterprise will receive savings in the use of heat due to the high calorific value of the coal from the Muz-Bulak deposit in the Uzgen district 30860 Qir, kJ / kg kcal / kg and low ash content of about 7.37 %.
