Throttle group is a set of throttle valves (arranged in parallel), used for gas purification: installed in gas purification complexes of blast furnaces.
Blast furnace gas is contaminated with bell furnace dust (particles of ore, coke, sinter, limestone, etc.). At the same time coke ovens and blast furnaces of blast furnace air heaters require gas purification up to dust concentration not higher than 10 mg/m3. To this end, metallurgical plants use purification of blast furnace gas in several stages. The highest quality - "fine purification" (dust concentration up to 10 mg/m3) of blast furnace gas is carried out in the throttle group.
Gas cleaning systems in metallurgical production work with increased gas pressure on the grate - throttle groups regulate gas pressure and purify it from dust.
Throttle groups provide high quality of gas purification in conditions of increased gas pressure on the grate (at a pressure drop of more than 20-30 kPa the dust content in the gas is reduced to 5-10 mg/m3), which makes their application in iron and steel industry indispensable - in the blast furnace - it will simplify and cheapen the gas purification system.
