Jackson, W M

A cold test cell of a stage cascade fluidized bed combustor (SCFBC) was constructed and operated. This test cell was used to demonstrate some of the critical phenomena involved in the staged cascade fluid bed combustion of coal. Studies were made of the fluid mechanics, heat transfer and sulfur capture characteristics of a stage cascade fluidized bed combustor and a process design model was developed. The experimental apparatus used and results obtained are described. The completed experimental program demonstrated that the initial estimates of the performance of the staged fluid bed combustor are achievable. Further work is necessary to optimize the stage design of the SCFBC and to design and develop mechanisms for varying distributor plate pressure drop and bed height to respond to changes in fuel, acceptor and air flow as a result of changes in demand for steam.
