Test G-22 was conducted August 30 to September 2 with the gasifier once again operating at 750 psig after conducting Test G-21 at 500 psig. The test was terminated when the slag tap burner shut down on September 2. Char feed to the gasifier was steady and able to be maintained for a significant period of time while the char valves were full open and there was no level in the feed vessel. When the valves were closed, a level established and the valves reopened; problems with char feed occurred. After a period of poor char feed, coal feed was reduced and the char vessel was emptied. Feed improved after these measures were taken, once again establishing that char feed with Illinois No. 6 coal can be readily maintained with the valves full open and no feed vessel level but once the valve openings are reduced and a level built, plugging develops. After conclusion of Test G-22 deactivation of the pilot plant was started. Operations and maintenance personnel worked on cleaning of vessels and mothballing of the equipment. 3 figures.
