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

采用高温碱熔--离子选择性电极法测量煤中氟化物浓度，并对测量过程中的影响因素进行了研究；同时对常用的几类煤中氟的分布规律作了柳步探讨，结果表明，该测量方法准确度较高，误差小，测量方便快速，实用性强，可作为煤中氟含量测量的一种有效方法；测量结果对煤种的筛选厦消除煤中氟污染有一定的指导意义。
