Experimental Study and Structure Optimization of a Uniflow Square shaped Cyclone Separator

Studied in the paper are the performance, separation efficiency and pressure loss of a uniflow square shaped cyclone separator which can be directly and easily installed on the water wall of a circulating fluidized bed boiler. To achieve an optimum structure, a variety of versions have been tested and analyzed. The test results show that the uniflow square-shaped cyclone separator with a cone shaped exhasust gas duct offers the advantages of a compact structure, high efficiency and low pressure drop, etc. The above cited merits are of great help in realizing the scale up of circulating fluidized bed boilers.
