The progress of the water cooled separator CFB boiler in China
- and others
Since the first pilot 75 t/h water cooled separator CFB boiler was in operation in 1996, a hot test program has been conducted by Tsinghua University and several boiler works, so as to promote scaling of the CFB boiler. The present paper introduces the test program and the primary results, such as the separator efficiency, material balance, solid bulk density, heat transfer along the height of the furnace, etc. Besides the traditional test technology, some newly developed apparatus was used in the hot test. According to the experience obtained from the boiler, the improvement measure was taken for the second and third boiler, which were in commercial operation in 1998. The first operation experience of the second and third boiler proves the effect of the improvement. Considering the experience and the test program, the scaling up design of water cooled separator was done. The present paper also introduces the design consideration of the 130 t/h and 220 t/h CFB boiler.
