Abstract: Installation includes a throttle assembly built in the blast-furnace outlet pipe and at least two gas turbines with blast furnace gas heaters also built in the outlet pipe and being parallel with the throttle assembly. Each of the gas turbines having a control diaphragm and a stop diaphragm is provided with a separate drive for turning thereof. The installation is also furnished with an isodromic regulator, for the gas pressure under the shaft top of the blast furnace, electrically connected to the separate drives of the throttles, being a part of a throttle unit and by means of a logic control unit being connected to separate drives of the control diaphragms of the gas turbines. The regulator preselects a sequence of operation of the above drives, when in the process of gas pressure control under the shaft top in the super-capacity blast furnace, to open in the first-turn the control diaphragms of the gas turbines and then to open the throttles which are a part of the throttle assembly.
