Control of pressure in coke oven in charging of coal
专利汇可以提供Control of pressure in coke oven in charging of coal专利检索，专利查询，专利分析的服务。并且PURPOSE: To control the pressure in a coke oven and to prevent leak of dusts and gasses, and entry of air, by controlling the effect of an ejector in a rising bend pipe in such a way that the momently measured value of the pressure in the coke oven becomes the given preset pattern from the beginning of charging of coal to the closing of the charging hole.
CONSTITUTION: The momently measured values of the pressure in the rising tube 1 or in the carbonization chamber 2 by the pressure gages 3 and 4 are input to the control device 5, which judges whether the measured values are coincident with the pattern given by the setting device 5. When the values are deviated from the pattern, the divergence of the control valve 9 of ammonia liquor is regulated, and flow rate (ammonia or steam) for an ejector from the flushing nozzle 8 of the ammonia liquid equipped on the bend pipe is adjusted so that the pressure in the oven is controlled.
