Cleaning of blast furnace gas the process of liquid iron production in the blast furnace bf generates gas at the furnace top which is an important by product of the bf process this top gas of the blast furnace is at the temperature and pressure existing at the bf top and usually contaminated with dust and water particles. Blast furnace top gas is scrubbed with water in the annular gap scrubber to obtain the desired residual clean gas particulate concentration the quantity of water required for scrubbing is relatively low and thus the gas cooling requirements normally determine the total water flow rate. The blast furnace for smooth and stable furnace operation the top pressure must be controlled and held as constant as possible the gas cleaning system design must therefore be fully integrated with the operation of the blast furnace during operations such as charging tapping equalisation and change of stoves there are inevitably. Wet dedusting system for blast furnaces meeting environmental standards with highly efficient gas cleaning 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 casthouse and stockhouse dedusting for blast . Baosteel 4 blast furnace effective volume of 2200 cubic meters is a deep hearth furnace chunky blast furnace blast furnace gas the average amount of 380000 cubic meters hour blast furnace top pressure of 018 mpa blast furnace gas purification using wet two stage venturi system
