British Gas Corporation, Westfield Development Centre, technical support programme, report on run TSP001
Run TSP001 was the first run of a new program and the main objective was to commission the gasifier and its systems, both of which had undergone considerable overhaul and modification since the last test series. Important secondary objectives were to commission the newly installed fluxing system, to investigate the behavior of the gasifier on lower than normal loads and to run the gasifier briefly under the conditions projected for running on Ohio 9 coal during TSP002. Slagging gasification after a standard start up procedure and the gasifier ran for two days under these conditions to establish the integrity of the refurbished reactor and its systems. With the gasifier on standard loading, the fluxing system was commissioned, with enough flux (blast furnace slag) to increase the coal ash by approximately 15% being mixed with the coal as it flowed. This system worked successfully, with little effect on gasifier performance, slag tapping still being an easily controlled operation. After the fluxing period, low load trials were commenced with the gasifier loading being brought down in a stepwise fashion to 122,000 SCF/H oxygen over 16 hours. Steam/oxygen ratio and gasifier pressure remained constant at 1.35 and 350 psig. The load was later returned to 130,000 SCF/H oxygen. Post run inspection revealed that good conditions had prevailed in all gasifier systems and internals and no repairs or modifications to the gasifier itself will be required for TSP002. All run objectives were achieved.
