Industrialization of efficient pulverized coal boiler system technology
SONG Chunyan
Abstract：In order to verify the advantages of pulverized coal boiler versus traditional industrial coal-fired boiler and promote the develop-ment of coal combustion in a cleaner way,an efficient pulverized coal boiler system developed by Shendong Coal Group was taken as re-search object. The technology was adopted by 6 mining areas of Shendong Coal Group and its application in 18 boilers whose stove load was 516 t/h in total was investigated. The reduction of flue dust,SO2 and NOx were 210,467,643 t during two heating seasons,the energy-saving benefits was calculated. The average thermal efficiency of 18 boilers was above 90%,the rate of coal saving was about 52%,the en-ergy-saving benefits was RMB 1. 5×108. The results showed that,the efficient pulverized coal boiler system had high thermal efficiency and stable performance. The positive,negative and average thermal balance efficiency was 93. 21%,90. 42%,91. 82%,so the efficient pulverized coal boiler system technology fit in the traditional industrial coal-fired boiler.
