Conceptual design and assessment of a pressurized circulating fluidized-bed boiler. Final report
This report presents a technical feasibility study of a turbocharged boiler employing a Lurgi circulating fluid bed combustion system operating at 10 atmospheres pressure. The study is based on a 250 MW(e) plant firing a high sulfur Illinois No. 6 bituminous coal. The basic design objective was to develop a plant with components that can be shop-assembled and transported to the plant site by barge on the nation's inland waterways. The study was jointly undertaken by Combustion Engineering, Inc., Lurgi Corporation, and Westinghouse Electric Corporation and included development of design parameters, a conceptual design and general arrangement, a control philosophy, and identification of areas where further development is needed. The methods utilized to determine the feasibility of the pressurized circulating fluid bed system and to develop system concepts were based on Lurgi's extensive experience in atmospheric circulating fluid bed technology. The system consists of the same components as used in an atmospheric circulating fluid bed system, but designed for operation at 10 atmospheres. The principal conclusions of the study are that the concept of burning coal in a circulating fluid bed can be applied to a system operating at 10 atmospheres, that shop fabrication can be maximized, and the system components can be barge shipped. The conclusions also indicate that this concept is a viable method for providing incremental steam generating capacity either in existing plants or in first generation steam plants.
