Blast Furnace Gas Cleaning System Ppt

The primary function of the blast furnace gas cleaning system is to remove particulate matter from this gas.

Blast furnace gas cleaning system ppt. 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. 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. 2 3 blast furnace gas has a modest heating value from the carbon monoxide and hydrogen that it contains. In addition the system also cools the gas to reduce its moisture content thus increasing its calorific value.

It is narrow at the top and has an arrangement for the introduction of ore and outlet for gases. Blast furnace gas it is the by product of blast furnaces that is generated when the iron ore is reduced with coke to produce molten iron. Heated with help of hot gases. 5 4 4 gas cleaning system gases generated during the reduction process in the blast furnace pass through the gas cleaning system.

The recovered sludge dust contains relatively high quantities of iron and carbon and can thus be recycled through the sinter. Day 5 cast house introduction blast furnace structure principle components of the charge 6. Improvement in blast furnace performance top pressures above 15 psig are becoming more common and some furnaces are operating at top pressures as high as 30 psig. Day 4 stock house sending charge to the furnace screening 5.

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. Day 8 gas cleaning plant main components of.
