ENHANCEMENT OF REFRIGERATION EFFECT USING FLUE GASES FROM CHIMNEY

Present work is focused on finding out the way to control the release of greenhouse effect gases. Global annual mean survey says, the CO2 concentration has substantial increment of 45%. Frequently from the start of the industrial revolution, effect of greenhouse gases on environment is more so it requires necessary action to control the percentage of gases. Keeping in view of this point, flue gases which are released from a Power-plant is considered as the input to run the Vapour Absorption Refrigeration System. Aqueous Ammonia Refrigeration System is used where ammonia is used as refrigerant and water as absorbent and the heat produced by the flue gases, NH3 changes its phase from liquid to vapour and this vapour circulates throughout the cycle and at the end, in the evaporator we get the cooling effect. In this system instead of utilizing electricity to run the system we focused to run the system by waste heat which is release from the turbine exit in the form of flue gas. By making it done its possible to release less harmful gases to the environment. Numerical calculations were conducted by varying the inlet pressure of the flue gases at the exit of the turbine. From the results it has been clearly observed that there is significant amount of increment in COP of the system.
