Work was initiated in January 1983 on reactivation of the BI-GAS pilot plant in preparation for operation with Illinois No. 6 coal. The test program for using Illinois coal was completed for review by the Morgantown Energy Technology Center (METC). Equipment preparations included checking the fuel oil system, cooling water tower, service water system, plant air system, the low pressure boiler and the demineralizer. In addition, a new coal cyclone was ordered as well as pall rings for the H/sub 2/S stripper. A program developed by Stearns-Roger Inc., in Denver for calculating plant mass and energy balances was entered into the Homer City computer. Reactivation of the BI-GAS pilot plant continued through the month of February with approximately fifty percent of the required work being completed. In addition to the reactivation, several projects were initiated or completed including (1) development of an on-line heat and material balance through the data acquisition system for use during actual plant operation, (2) revisions to operation of the slag tap and slag heating burners, (3) a steam desuperheater for the slurry preheater, and (4) a study to convert the BI-GAS gasifier to single-stage operation. Reactivation of the BI-GAS pilot plant proceeded during March 1983 with completion expected in April. The test program for G-20, scheduled for May 1983, was issued along with modifications prior to the test. Calculations were done to determine if the gasifier can be operated at 500 psig. In general, it was found that few plant modifications would be necessary to operate at the lower pressure. 5 figures, 4 tables.
