Test Results from the Co-firing of Coal Water Slurry Fuel in a 32 Megawatt Pulverized Coal Boiler

摘要

1. CWS was successfully co-fired in a 32 MWe utility boilerwithout disruption of boiler performance.2. Low solids CWS co—firing results in a reduction in NOx by15 to 20% under the conditions tested at the Seward Station.3. Emission levels of CO, SO_2 and particulates, as indicated byopacity measurements, were essentially the same as with normal pc firing levels but CO levels were highly variable.4. CWS handling and feeding systems installed at the SewardPlant performed within design parameters.5. CWS firing was successfully integrated into the boilercontrol system.6. Seward Station plant operators accepted the CWS firing asroutine by the end of the test program.
