PULVERIZED COAL BURNER AND SUSPENDING COMBUSTION TECHNIQUE FOR REHEATING FURNACE
Liu Yanchun Wang Zhangbao (East China Metallurgical Institute) Xu Jianshi (Changshu Burner Works)
Three types of circular double concentric jet pullverized coal burners(MFP, MPY and MLP) and their experimental results and applications are described in this article. The major items are;
1) Air swirl generated by movable-block swirl generator;
2) Bluff bodies set in to combustion nozzles;
3) Fitting of divergent extension to MPY type and MLP type burners;
4) The heat required for ignition can be met by the hot combustion products recirculated in the vortex.
