RESEARCH ON EFFECTS OF COAL PULVERIZATION SYSTEM'S OPERATION MODE TO REDUCING BOILER FLUE GAS TEMPERATURE[J]. Thermal power generation, 2000, (4): 45-46.DOI:
One important factor causing flue gas temperature higher in No. 2 boiler of Yaomeng power plant is too much cool air mixed into coal pulverization system and the primary
which reduces the flow to air preheater. Through installing recirculation tube on the mill and shrinking the primary air pipe diameter
the percentage of cool sir to combustor is reduced by 8. 12% .The calculation predicts 13℃ flue gas temperature decrease. The retrofit test shows that the temperature is reduced by 15. 1 ℃. The boiler efficiency is improved by 0. 823%.
