Development and Testing of Industrial Scale, Coal-Fired Combustion System: Phase 3.
In the first quarter of calendar year 1997, 17 days of combustor- boiler tests were performed, including one day of tests on a parallel DOE sponsored project on sulfur retention in a slagging combustor. Between tests, modifications and improvements that were indicated by these tests were implemented. This brings the total number of test days required to meet the task 5 project plan. The key project objectives in the areas of combustor performance and environmental performance have been exceeded. With sorbent injection in the combustion gas train, NO{sub x} emissions as low as 0.07 lb/MMBtu and SO{sub 2} emissions as low as 0.2 lb/MMBtu have been measured in tests in this quarter. Tests in the present quarter have resulted in further optimizing the sorbent injection and NO{sub x} control processes. A very important milestone in this quarter was two successful combustor tests on a very high ash (37%) Indian coal. Work in the next quarter will focus on commercialization of the combustor- boiler system. In addition, further tests of the NO{sub x} and SO{sub 2} control process and on the Indian coal will be performed.
