METHOD FOR USING THE EXHAUST GASES FROM PLANTS FOR RAW IRON MANUFACTURE FOR GENERATING STEAM |
摘要 |
A method and a system for generating steam using the waste gases from plants for pig iron manufacture: waste gas removed as export gas (12) from the plant for pig iron manufacture is thermally utilized by combustion, and the waste gas from the combustion is fed to a heat-recovery steam generator (29). To utilize more energy from the export gas (12) for power generation, the export gas (12) is fed into a combustion chamber (23) located upstream of the heat-recovery steam generator (29), and after the combustion in the heat-recovery steam generator (29), heat is extracted from the export gas (12) without the export gas (12) passing through a gas turbine between combustion and heat-recovery steam generator. The pressure in the combustion chamber (23) and heat-recovery steam generator (29) are set above atmospheric pressure by means of a gas flow regulator (31) that is located downstream of the heat-recovery steam generator (29). |
