THERMODYNAMIC ANALYSIS OF AIR CONDITIONING SYSTEM USING WASTE HEAT OF STEEL PLANT

Abstract

iv Abstract This report is concerned with an idea of Air conditioning in an integrated steel plant using waste heat recovery unit and vapour absorption refrigeration system. As we know that in an integrated steel plant hot metal is produced in blast furnace and this hot metal is converted in to steel in LD converter. This molten steel is casted in to slabs and ingots for the production of HR coils, CR coils and Rails etc. In all these processes lot of heat input is required and out of which lot of heat is rejected to the atmosphere in the form of waste heat. During casting of slabs in continuous casting shop of the steel plant cooling of molten steel takes place and the heat stored in the steel is rejected to the atmosphere, we can use this waste heat using a waste heat recovery system. This waste energy or heat can be used to carry out different processes and one of them is Air conditioning.
