ABSTRACT:
A device for protecting a turbine driven by an exhaust gas of a blast furnace from a high temperature gas generated and discharged when the blow-out phenomenon takes place in the blast furnace is disclosed. In this protective device, occurrence of the blow-out phenomenon is detected, and cooling water is sprayed in an exhaust gas or in the turbine to lower the temperature of the gas, or cooling water is directly sprayed to a part of a material which readily undergoes thermal degradation to cool the material.
