The first pilot compact CFB boiler with water cooled separator in china

摘要

The square cyclone was experimentally investigated in Tsinghua University. The flow field in cyclone was measured and numerically simulated. The investigation prove that the corner of square cyclone created turbulence to decrease the collection efficiency. The acceleration of solid particles at the inlet of the square cyclone was also factor for good efficiency. The collection efficiency has been improved by a carefully designed curved inlet of the cyclone which received the patent in China (ZL 93 2 35842.X)
