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 in 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 also connected to separate drives of the control diaphragms of the gas turbines it preselects such a sequence of operation of the above drives when in the process of the gas pressure control under shaft top in supercapacity blast furnace to open in the first-turn the control diaphragms of the gas turbines and then to open the throttles which being a part of the throttle assembly. But when closing the throttles are operated in the first turn and after that the control diaphragms are closed. Connected according to an electric circuit contacts of switches are switched on by the logic control unit. The control diaphragms of the gas turbines are furnished with switches operating when the control diaphragm turning at a position of closing up to the position corresponding to a given gas flow rate.
