How does the gas generation section of synthesis ammonia react?

Gas production is essentially a reaction of carbon with oxygen and steam. Raw coal is intermittently fed into a fixed-layer gas generator, where air is first blown in to raise the temperature of the furnace, and then water steam and nitrogen-added air are added for gas production. The resulting semi-water gas (mainly composed of CO and H2, with other impurity gases) goes into the scrubber tower for dust removal and cooling, and is finally fed into the semi-water gas cabinet.
