Sintering behavior of flying slag particles in entrained-bed coal Gasifiers (3rd report, effect of soot on sintering behavior of flying slag particles)

摘要

The effect of char addition on sintering behavior of flying slag particles in an entrained-bed coal gasifier was examined using four kinds of amorphous water-quenched slag obtained at the pilot plant of HYCOL. This plant was designed to gasify 50 tons of coal per day. The sintering temperatures of the four slags without char were all approximately 800℃. However, taiheiyo coal slag did not sinter at 900℃ when the char added.
