Experimental Study on the Operational .

In this paper, an advanced two-stage entrained-flow coal gasifier was built and its operational performance was examined. Detailed comparisons between exit gas compositions, consumptions of coal and oxygen, carbon conversion efficiencies, and cold gas efficiencies in single- and two-stage operational modes have been experimentally performed. The results showed that the coal and steam supplied ...

01/12/2019 · The gasifier using sub-bituminous coals generated more heat (93.52–98.1 MW) than the gasifier using bituminous coals (84.61–86.17 MW) because the volume of coal was greater. However, since more drying energy was needed for sub-bituminous coals, the amount of heat supplied to the HRSG (39.16–53.71 MW) was less than that of bituminous coals (75.51–84.39 MW). The additional .

14.02.2019 · When a plasma torch reactor is used for the gasification of coal, process energy is supplied by the plasma torches only and no coal combustion is carried out. Thus the calorific value of the coal is irrelevant. However the volume and quality of the syngas as well as the economic viability of the process depend on the carbon content of the coal and on the process efficiency. The latter ...
