Pilot Experiment of Filtration System of Blast Furnace Hot Gas

A pilot experiment of hot coal gas filtration, which using sintered metallic woven mesh as filter, is completed and the whole experiment process is controlled and detected by computer. The test results show that the new developed hot gas filtration system can be used at a temperature range of 550 ℃-600℃ while the filtration efficiency is 99.9%. The dust contentration of the gas after the filtration is below 10 mg/m³. So the hot gas filtration system can be used in the oxygen blast furnace process.
