一、概述鞍钢高炉炉顶煤气压力一般为0.5～0.8公斤/厘米~2,用于煤气净化需要消耗0.25公斤/厘米~2的压力,净煤气管网压力为0.12斤/厘米~2左右,其余全部消耗于减压阀组的节流上。实践证明,作为控制炉顶煤气压力的减压阀组,要求的压力降可约为0.1公斤/厘米~2,所以尚有大量剩余压力可以利用。现在不仅剩余压力没有利
First, an overview of Anshan Iron and steel blast furnace top gas pressure is generally 0.5 ~ 0.8 kg / cm ~ 2, for gas purification need to consume 0.25 kg / cm ~ 2 pressure, net gas pipeline pressure of 0.12 kg / cm ~ 2 or so, the rest All consumed in the throttle valve throttle. Practice has proved that as the pressure control valve top gas pressure relief valve group, the required pressure drop can be about 0.1 kg / cm ~ 2, so there is still a lot of residual pressure can be used. Now, not only is the residual pressure unfavorable?
