增压沸腾床平均粒径及浓度在线测量

On-Line Measurements of the Mean Size and Concentration of Darticulate of the Pressurized Fluidized Bed Combustion

增压沸腾床平均粒径及浓度在线测量戴立铭，李鹤立，江潼君（东南大学动力工程系，南京２１００１８）为提高热交换效率，减少环境污染，采用增压沸腾燃烧是必由之路。由于沸腾燃烧后使燃气中含有大量的不同粒径的灰尘，燃气不能直接进入燃气透平，必须经过净化系统过滤使...

According to the requirement for measuring mean size and concentration of particulate down-stream of the gas clean- up syistems of the PFBC,three measurement methods are intreduced,and the two-wavelength optical extinction is presented, it is the most pronusing measurement techniquein the build-up model, the measurement condisions the implementation request and the prevention ofpollution at the optical windows for application of the PFBC two-phase flow.
