ABSTRACT:
The present invention relates to a method and apparatus for recovering energy from a blast furnace exhaust gas by utilizing an axial-flow turbine. According to the method of the present invention, a blast furnace exhaust gas is first passed through a wet scrubber to remove dusts and form a saturated gas, and low temperature water is sprayed to the saturated gas to add condensed mists to the gas. According to this method, adhesion of dusts to a turbine can be effectively prevented. When large nozzles and large moving blades are used for the turbine for use in practising this method, adhesion of dusts and erosion of nozzles and moving blades can be effectively prevented. This energy recovery method can be practised very advantageously by using an axial-flow turbine in which the gas flow-out direction at the nozzle outlet is made in agreement with the gas flow-out direction at the moving blade outlet to always impart to the gas a swirling speed around the axial center of the turbine, so that the dusts and mists are shaken off from the gas.
