Coal-fired high performance power generating system. Quarterly progress report, October 1, 1994--December 31, 1994
This report covers work carried out under Task 3, Preliminary R and D, under contract DE-AC22-92PC91155, {open_quotes}Engineering Development of a Coal-Fired High Performance Power Generation System{close_quotes} between DOE Pittsburgh Energy Technology Center and United Technologies Research Center. The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) by the year 2000 that is capable of (1) > 47% thermal efficiency; (2) NO{sub x}, SO{sub x} and particulates {<=}25% NSPS; (3) cost {>=}65% of heat input; (4) all solid wastes benign. In our design consideration, we have tried to render all waste streams benign and if possible convert them to a commercial product. It appears that vitrified slag has commercial values. If the flyash is reinjected through the furnace, along with the dry bottom ash, then the amount of the less valuable solid waste stream (ash) can be minimized. A limitation on this procedure arises if it results in the buildup of toxic metal concentrations in either the slag, the flyash or other APCD components. We have assembled analytical tools to describe the progress of specific toxic metals in our system. The outline of the analytical procedure is presented in the first section of this report. The strengths and corrosion resistance of five candidate refractories have been studied in this quarter. Some of the results are presented and compared for selected preparation conditions (mixing, drying time and drying temperatures). A 100 hour pilot-scale stagging combustor test of the prototype radiant panel is being planned. Several potential refractory brick materials are under review and five will be selected for the first 100 hour test. The design of the prototype panel is presented along with some of the test requirements.
