一、前言高炉煤气是高炉冶炼过程的副产品,含有一定可燃成分,主要作燃料利用。因此要求其含尘量、含水量尽可能低,以得到较高的燃烧温度。采用合理的高炉煤气净化工艺,降低煤气含尘、含水量,提高煤气显热,保护其物理热量,已成为当今冶金企业节能、挖潜的方向之一。原马钢一铁9号高炉煤气净化采用传统的湿式除尘工艺(高炉→重力除
I. Introduction Blast furnace gas is a by-product of the blast furnace smelting process and contains certain combustible components, mainly for fuel utilization. Therefore, its dust content, moisture content as low as possible, in order to get a higher combustion temperature. Using reasonable blast furnace gas purification technology to reduce gas dust, water content, improve gas sensible heat, protect their physical heat, metallurgy enterprises have become today’s energy-saving, tapping the potential of one. The original Malhegan Iron 9 blast furnace gas purification using traditional wet dust removal process (blast furnace → Gravity
