Development of high temperature turbine subsystem technology to ''technology readiness status'': Phase I. Quarterly report, June--September 1976
The requirements of overall plant design descriptions (OPDD's) for combined cycle plants utilizing coal-derived low-Btu fuel gas and coal-derived liquid fuel resulted in evaluations of various coal gasification processes including fixed-bed and entrained-bed. An advanced fixed-bed concept was selected which operates at a very low steam to air ratio, achieves a cleaner more tar-free operation and utilizes the coal fines mixed with tar. The Foster-Wheeler (FW) entrained-bed system offers a high throughput with a savings in equipment costs. The availability of an efficient high temperature gas cleanup system would make the overall FW System attractive. The Benfield System was selected following evaluation of low temperature gas cleanup systems. Various design concepts are presented which represent the current status of various turbine configurations utilizing different blading cooling concepts. These involve water, steam and/or air cooling. Three combustor conceptual designs are presented including a circular can type, a rectangular can type and an annular combustor. A major study on the controls requirements for a combined cycle plant with a fixed-bed gasifier and a gas cleanup system was completed and included herein.
