Abstract

Aimed at aforementioned problems existing in industrial boilers, with a research object of coal-fired boilers in Liaohe Oilfield Shenyang Engineering Technology Department, this paper has calculated emissions of gaseous pollutants from coal-fired boilers including TSP, SO₂, NO_x and CO and the trace element mercury. It has also pointed at excessive condition of emission pollutants TSP and SO2, integrated with energy consumption of industrial coal-fired boilers, and taken measures like transformation of boiler energy-saving and emission reduction technology for further energy conservation and emission reduction. Pollutant emission level and emission factors have indicated that, concentration of pollutants discharged by industrial coal-fired boilers is relatively high, and some pollutants have severely exceeded the standard. The results show that: energy-saving measures have totally saved 900 tons of coal, 200 thousand kilowatts of electricity. Emission concentration of TSP has decreased from 348 mg/m³ to 176 mg/m³, and emission concentration of SO₂ has decreased from 1274 mg/m³ to 815 mg/m³. There exist obvious effects of energy saving and emission reduction.
