A new technology of Controllable Pulverized Coal Rict/Lean Swirl Combustion, developed by Zhejiang University. is introduced in this paper. The technology is used for the low load flame stabilization of pulverized coal without support oil, prevention of furnace wall slagging and low NOx emission. The pulverized coal in primary air is separated into two tang-type streams of air-coal flow, one(inner ring) is the rich pulverized coal stream and other(outlet ring) is the lean pulverized coal stream. Rich pulverized coal stream is guided to the boundary, of hightemperature recirculation zone. Lean pulverized coal stream is located outside of the rich pulverized coal stream. The experimental results show that the rich/lean ratio is up to 5~7: 1. pressure loss is about 400~500Pa. The application has been achieved on #2 boiler in Hefei Power Plant

The No2 unit(6701/H, 200MW) at Hebi Wanhe Power Generation Co Ltd., was put into use in 1992 This is a coal-fired boiler with tangential fired method The design coal is Hebi lean coal To stabilize the combustion without oil at low load, eight original designed burners placed to No 2 and 3 level on the NO2 boiler were replaced with the controllable pulverized rich/leab ones developed by the Institute for Thermal Power Engineering(ITPE) of Zhejiang University The practice of successive operation shows that stable combustion can be achieved at 50% load without support oil, even at he combustion without oil at low load, eight original designed burners placed to No 2 and 3 level on the NO2 boiler were replaced with the controllable pulverized rich/leab ones developed by the Institute for Thermal Power Engineering(ITPE) of Zhejiang University The practice of successive operation shows that stable combustion can be achieved at 50% load without support oil, even at
