The effect of coal viscosity-temperature characteristics on the dynamic response of slag discharge behavior in Shell gasifier

Fuel, 2022
How to efficiently and quickly detect the slag blocking behavior of entrained flow gasifiers was an urgent engineering problem. At present, the syngas composition of the gasifier was usually detected to judge whether slag plugging occurred, which had ...
