A system for generating power with the top pressure of a plurality of blast furnaces by leading a gas from the top of the furnaces into turbines, corresponding in number to the furnaces, to convert the pressure of the gas into rotational energy and generate power by a generator coupled to the turbines. The turbines connected to the furnaces by main gas channels individually are aligned with their rotor shafts connected together into a single shaft which is connected to the generator. Preferably each pair of the adjacent turbines are arranged with their intake ends positioned in the center of the arrangement so that the gas flows toward the exhaust ends at both sides, or with their intake ends positioned at both sides to cause the gas to flow toward the exhaust ends in the center. The single shaft connecting the pair of turbines together has no intermediate bearing between these turbines.
