For a pressure high furnace blast furnace gas cleaning plant

摘要

The throat gas is piped to a first purifier, =1 prewasher and then to a washer (I) using differential press. control, followed by a separator for the droplets formed. Two washers of types (I) are used, the novelty being that one is used to maintain a constant press. in the blast furnace throat, the other leading to an expansion turbine driving a generator. The two washers (I) can be connected either in series or in parallel, and the flow of gas to the turbine is pref.four times the flow in the other washer. Max. generation of electricity without affecting the gas press. in the throat is achieved
