In the second quarter of calendar year 1998, no work was performed on the present project. The 20 MMBtu/hr combustor-boiler facility was not operated during this period. The total test days on the Philadelphia facility to the end of June 1998 remained at 108 as in the previous quarter. Of these, 34 tests were part of the other DOE project. The test days on the other project are listed here because they demonstrate the durability of the combustor, which is one of the objectives of the present project. As noted previously, this exceeds the planned 63 test days for this project. All key project objectives have been exceeded including combustor durability, automated combustor operation, NO{sub x} emissions as low as 0.07 lb/MMBtu and SO{sub 2} emissions as low as 0.2 lb/MMBtu. In addition, a novel post-combustion NO{sub x} control process has been tested on a 37 MW and 100 MW utility boiler. Any further tests will depend on the results of evaluations of current and prior tests. The only effort remaining on this project is facility disassembly and Final Report. Also, as part of the commercialization effort for this combustor technology, Coal Tech is developing alternative designs of the combustor that allow its fabrication as substantially reduced costs from the present unit.
