Study of Vapour Absorption System Using Waste Heat in Sugar Industry

Most of the energies are utilized by the industries due to depletion of fossile fuels and increasing the fuel price to exploit the maximum presented energy from the waste heat source. The sugar industry steam turbine exhausts carry a considerable amount of thermal energy. This energy can be set in to positive use as a heat source for vapour absorption system to serves as cooling system. This paper illustrates the thermal and fiscal advantages of using single effect lithium bromide water absorption by means of waste heat. The objective of this work is to hypothetical design of lithium bromide water absorption Refrigeration system using waste heat from sugar industry steam turbine exhaust. The various parts of the vapour absorption system are absorber, solution heat exchanger, evaporator, condenser and generator. The hypothetical design based on the cooling effect required for DC thyrist motor in a sugar industry. Energy consumption and energy savings in terms of energy and fuels are calculated. The Overall heat transfer coefficient, effectiveness and COP of the heat exchanger are measured.
