As part of the Department of Energy's Clean Coal Progra,m, Coal Tech Corp. is demonstrating the commerical readiness of an advanced cyclone coal combustor for ''new'' or ''retrofit'' applications on industrial or utility boilers. This advanced combustor can control SO/sub 2/ and NO/sub x/ emissions to near new source performance standards and at the same time retain and reject ash, sorbent, and sulfur compound solids as slag upstream of the boiler. During this period, all the major components required for the modification of the combustor facility to dry coal operation were installed at the Keeler test site. This included the coal storage, delivery and feed system, and the stack particulate scrubber system. In addition, the controls for these sub-systems were installed. The installation work was completed at the beginning of November, somewhat less than one month behind the planned schedule. Figure 1 shows the combustor installed on the Keeler boiler, and figure 2 shows the boiler house and the scrubber and coal storage systems. Two combustor shakedown tests were implemented during Phase II. Additional short duration tests have been implemented in Phase III, for a total to date of 5 one-day tests, consisting of about 50 hours of combustor operation in which eight tons of dry pulverized coal were consumed. The combustor has been tested from coal start to full boiler thermal rating in several of the tests. When added to the coal water slurry tests which were implemented in the spring of 1987 under another project, the total combustor operating time has reached 90 hours, and 18 tons of coal fuel have been consumed.
