上钢一厂于1959年建成255mm~3高炉两座,每座高炉产生40000Nm~3/h煤气,虽经重力除尘器、洗涤塔、文氏管及脱水器除尘脱水,但煤气含尘量仍高达130～150mg/Nm~3。所产煤气约一半供热风炉自用,其余供平炉车间和二转炉车间、烘包使用,多余部分则高空放散,放散量1.2～1.8万米~3/h。 锅炉房原设 K_4—13锅炉5台。燃用低热值的高炉煤气后,出力明显不足,5台锅炉共出蒸汽约10t/h,只及额定负荷的一
A steel plant in 1959 built 255mm ~ 3 blast furnace two, each blast furnace produce 40000Nm ~ 3 / h gas, though gravity dust collector, scrubber, venturi and dehydrator dedusting, but the gas dust content is still Up to 130 ~ 150mg / Nm ~ 3. About half of the gas produced by the stove for personal use, and the remaining for the furnace shop and the second converter workshop, drying package use, the extra part of the high-altitude discharge, the discharge of 1.2 to 18,000 m ~ 3 / h. The original boiler room K_4-13 5 sets of boilers. Burning low-calorific blast furnace gas, the output was significantly less than 5 boilers out of steam about 10t / h, and only the rated load of a
