In the blast furnace smelting process, blast furnace gas is the emission gas from top stack through dedusting, filtering and purging. As a byproduct material in the blast furnace process, blast furnace gas is flammable and explosive. Therefore, on line monitoring system is required in the production process to ensure the production safety.
