Description

technical field [0001] The invention relates to the technical field of pulverized coal gasifiers, in particular to an optimized coal blending system for pulverized coal gasifiers used for methanol production. Background technique [0002] The pulverized coal gasification furnace is composed of a furnace hearth, a U-shaped return pipe and a cyclone separator. The pulverized coal with a particle size of 0-10mm circulates in the furnace and is fully and uniformly contacted with the gasification agent, thereby greatly improving the coal conversion rate. The special structure of the pulverized coal gasifier determines that the furnace has high gasification efficiency, high coal conversion utilization rate, and more energy saving; [0003] By putting pulverized coal, oxygen and water vapor into the pulverized coal gasifier for gasification reaction, a large amount of carbon monoxide and hydrogen can be obtained, and carbon monoxide and hydrogen are the most direct material gases f...
