All the existing entrained-flow gasification technologies belong to the technology of high slaggingtemperature process so that domestic resourceful double-high coal cant be used.
现有的气流床气化技术均为高温熔渣气化技术，使国内资源丰富的双高煤无法利用。

The result shows that the high metal contents of the residuum andhigh temperature of the gasifier are the main reasons for slagging and block up in the gasifier.
结果表明，渣油中金属含量高及气化炉温度过高是气化炉结渣与堵塞的主要原因。

The slagging, fouling and abrasiveness performances of co-firing low-temperature pyrolyzed biomass with coal depend on the ash content, the ash component of them and their blending rate, etc.
