ABSTRACT:
Stack gas is first passed through a coarse-particle separator and then a prescrubbing tower. Then this gas, which is under pressure, is passed through a pair of Venturi washers. The output side of one of the washers is connected directly to a droplet separator at the output of the system. The outlet of the other Venturi washer is connected through a turbine driving an electric generator and having its output side in turn connected to the droplet separator. The control body of at least the washer which is connected directly to the droplet separator is adjustable so as to maintain a constant back pressure in the system at the blast furnace from which the stack gas comes. The Venturi washer connected to the turbine is set up to pass at least four times as much of the gas as the other Venturi washers so that most of the gas passes through the turbine, undergoing a pressure drop that is transformed into the work of driving the turbine and generates electricity.
