发电用煤如进行洗选,则锅炉的烟道气不必再脱硫。同时还能延长锅炉寿命。我们在试验室研究了三种不同的静电分选方法,如旋流器分选;流态化床分选和筒式分选,用以分选磨细的粉煤(供粉状燃烧的-200网目占80%的粉煤)。研究的目的是确定哪种方法能取得最佳分选效果。 Power generation coal, such as washing, the boiler flue gas desulfurization do not have to. At the same time can also extend the boiler life. We studied three different electrostatic separation methods in the laboratory, such as hydrocyclone sorting, fluidized bed sorting and cartridge sorting, to sort the finely divided pulverized coal (for pulverized combustion - 200 mesh accounts for 80% of the pulverized coal). The purpose of the study was to determine which method gave the best separation.
