Blast Furnace Gas Cleaning System

Casthouse and stockhouse dedusting for blast.

Blast furnace gas cleaning system. The recovered sludge dust contains relatively high quantities of iron and carbon and can thus be recycled through the sinter. Our technology base covers the entire blast furnace process route from hot blast and raw material handling through the furnace and casthouse to gas cleaning and hot metal slag processing. Our solutions extend from minor plant upgrades through products and automations systems to complete turnkey installations all executed by our expert. Blast furnace gas cleaning plant example of analysis results of blast furnace gas cleaning plant internal gas flow a blast furnace gas cleaning plant capable of 30 0 83 t pig more trt power generation than the conventional wet type method and 6 0 21 t pig more than the conventional dry type bag filter method.

As a state of the art system integrator for blast furnace dedusting equipment primetals technologies offers comprehensive in house solutions for primary and secondary offgas treatment. The gas is burned to recover. In addition the system also cools the gas to reduce its moisture content thus increasing its calorific value. Blast furnace gas has a modest heating value from the carbon monoxide and hydrogen that it contains.

The molten iron is removed near the bottom of the. Recent developments in blast furnace operation characterised by long campaign life combined with ever increasing productivity and high rates of fuel injection require high efficiency top gas cleaning equipment to cope with the changes in top gas composition dust loading pressure and temperature fluctuations and match the campaign life of the furnace. Use of gas cleaning plants for cleaning blast furnace gases results in substantial savings in delivery costs throughout the extensive distribution system of the steel.

Wet dedusting system for blast furnaces meeting environmental standards with highly efficient gas cleaning. Furnace off gases firstly pass through a dust catcher to remove the large dust particles then through a gas scrubber and finally electrostatic precipitators to remove the fine particulates and other gas impurities. 5 4 4 gas cleaning system gases generated during the reduction process in the blast furnace pass through the gas cleaning system. The primary function of the blast furnace gas cleaning system is to remove particulate matter from this gas.
