Method of operating turbine in top pressure recovery facility of blast furnace and turbine for top pressure recovery facility of blast furnace

摘要

Problem to be solved: to avoid the wear and damage of turbine caused by dust contained in blast furnace gas, and This paper proposes the operation method of the turbine in the top pressure recovery facility of the blast furnace and the turbine for the top pressure recovery system of the blast furnace.In the method of operating a turbine for converting the energy of the blast furnace gas into rotational motion by installing the blast furnace gas at the top pressure recovery facility, the dust concentration in the blast furnace gas was measured at the gas inlet side and the gas outlet side of the turbine, respectively. When the measured dust concentration exceeds a preset threshold, the turbine is stopped.Diagram
