Top Pressure Recovery Turbines

Top Pressure Recovery Turbines

TRT is the Energy-saving equipment used for a blast furnace of steel plants, which has following two functions.One is to control the top pressure of a blast furnace, and the other is to generate electric power by driving a turbine using blast furnace gas generated in a blast furnace.
Kawasaki has acted as the pioneer and the leading supplier of this TRT, and played a role of energy saving and environmental improvement of world wide steel mills by the supply of this TRT.
