THERMODYNAMIC ANALYSIS OF BLAST-FURNACE TOP GAS PRESSURE RECOVERY TURBINES

摘要

The pressure existing at the top of modern large-size blast furnaces constitutes an exergy potential that can be used for the generation of electrical energy, provided the top gas is decompressed in a suitable recovery turbine.The aim of this paper is to examine such problem in general, considering literature and operation data, and specifically to compare the effect of dry or wet gas cleaning on the performance of blast-furnace top-gas turbines.
