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. It was considered that the char collected by the cyclon was a mixture of soot and unburned coal particles and the soot prevented the slag from sintering. Therefore, the effect of soot on sintering behavior was clarified using carbon black as soot. SEM and EDX analyses showed that very small soot particles acted as a dispersant in the slag.
