The objective of this program is to develop an integrated combustor/heat exchanger which burns coal either as a slurry or as dry ultrafine coal and which is suitable for use in a range of residential space heaters. The program has been divided into two phases. To date, Phase 1 has been completed. In Phase 1, combustor concepts were developed and evaluated by means of mathematical modeling and experimental testing. The most promising concept, an air-cooled stainless steel combustion chamber, was fabricated and tested. In Phase 2, an optimized prototype combustor will be integrated with a heat exchanger to complete the prototype residential space heater. This quarterly report describes the work performed on Task 2 --- Combustor Optimization. Initially the design of the combustor was optimized and included modifications of the burner and the combustion chamber. Combustion performance of the optimized combustor was conducted as well as the response time. 5 figs.
