Blast Furnace Gas Cleaning System

Wet dedusting system for blast furnaces meeting environmental standards with highly efficient gas cleaning.

Blast furnace gas cleaning system.

Blast furnace gas has a modest heating value from the carbon monoxide and hydrogen that it contains. 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. Our solutions extend from minor plant upgrades through products and automations systems to complete turnkey installations all executed by our expert. 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.

Gas cleaning systems in ironmaking blast furnaces in a blast furnace iron ore and coke are charged into the top of the furnace. 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. 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. Blast furnace gas cleaning systems high efficiency gas cleaning systems are vital for the reliable operation and long campaign life of high temperature hot blast systems and steam generation facilities and allow the operators to meet the relevant pollution control standards. 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. The gas is burned to recover.

The molten iron is removed near the bottom of the. The recovered sludge dust contains relatively high quantities of iron and carbon and can thus be recycled through the sinter. It is a page of the detail of blast furnace gas cleaning system ring slit washer rsw of steel plantech design manufacturing installation sales and after sales servicing of steelmaking machinery non ferrous metal producing machinery and coke making machinery as well as related equipment for use in japan and overseas. In addition the system also cools the gas to reduce its moisture content thus increasing its calorific value.
