Development and Testing of Industrial Scale, Coal-Fired Combustin System, Phase 3. Twenty second technical progress report, April 1-June 30, 1997

PDF Version Also Available for Download.

Description

In the second quarter of calendar year 1997, 9 days of combustor- boiler tests were performed, including 3 days 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 to the end of June 1997 in the task 5 effort to 83 days. This compares with a total of 63 test days needed to complete the task 5 test effort, and the number of tests days required to meet the task 5 project plan ... continued below

Description

In the second quarter of calendar year 1997, 9 days of combustor- boiler tests were performed, including 3 days 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 to the end of June 1997 in the task 5 effort to 83 days. This compares with a total of 63 test days needed to complete the task 5 test effort, and the number of tests days required to meet the task 5 project plan have been completed. 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 S0{sub 2} emissions as low as 0.lb/MBtu have been measured in tests in the previous quarter. The emphasis of tests in the present quarter have been on further optimizing post-combustion sorbent injection for S0{sub 2} and NO{sub x} control processes, with most of the test effort focused on the NO{sub x} control process. Many factors which control the NO{sub x} reduction were identified in tests on the 20 MMBtu/hr combustor-boiler. Another very important milestone in this quarter was the successful test of this Coal Tech post combustion NO{sub x} control process on a 100 MAR utility boiler, where in a preliminary test 25% NO{sub x} reduction was measured.
