2Circulation sprays in the State of Blast Furnace from the shaft position in the back.The recycle blast furnace gas need be heated certain temperature, otherwise a large amount of cooled coal gas blows people's oxygen blast furnace, has destroyed the thermal equilibrium in the stove, and energy consumption raises on the contrary.The blast-furnace hot-air heating technique is very ripe, but the coal gas heating than the hot blast difficult heating many.On the one hand owing to CO content in the oxygen blast furnace circulating gas is higher than H far away
2So CO can analyse carbon in the coal gas heat-processed, not only reduced effective coal gas amount, and can influence the coal gas heating efficiency; There is potential safety hazard in coal gas heating on the other hand, blasts easily in the heat-processed and accident such as gas leak.The coal gas heating technique comparative maturity of Midrex and HYL, but mainly heat hydrogen-rich gas, do not analyse the problem of carbon basically.
