OSTI ID:5689263
This report describes the test activities, test results and analyses associated with the evaluation of the slag shedding characteristics of a water-cooled metal liner in an entrained-flow coal gasifier. A major technical issue in the development of commercial entrained-flow coal gasifiers is wall durability. The high temperature and corrosive/erosive environment existing within an entrained-flow coal gasifier results in ceramic liner damage and reduced operational life. Previous experimental programs conducted by Bell Aerospace identified a water-cooled metal liner, or ''cold wall'', as an attractive gasifier liner option to alleviate the durability problem. A test program was conducted at the Bell High Mass Flux (HMF) gasifier test facility to further evaluate cold wall slagging characteristics. The basic HMF gasifier operates at a coal throughput of one-half ton of coal per hour, a pressure of fifteen atmospheres, and processes coal and oxygen to produce a synthesis gas. The tests were conducted using Illinois No. 6 coal and North Dakota lignite. Post test observations and data analysis indicate the slag/ash shedding occurred on a periodic basis throughout gasification tests of up to one hour duration. 30 figs.
