thermodynamic analysis of combined open- cycle- twin- shaft gas turbine (brayton cycle) and exhaust gas operated absorption refrigeration unit carry a significant amount of thermal energy that is usually expelled to the atmosphere without taking any further part in the power generation processes. The low grade thermal energy can however be put to beneficial use. This paper explores the utilisation of the exhaust gases of an open-cycle -twin -shaft gas turbine. An air standard cycle is assumed for the gas turbine, first with the aid of thermodynamics laws the specific net work and the efficiency of the cycle as a function of temperature ratio and pressure ratio of the cycle are calculated, and the realistic bounds placed on the cycle by the thermodynamic analysis is shown. Then the temperature of the exhaust gases and the heat that can be put into beneficial for precooling in terms of temperature ratio and pressure ratio of the cycle are determined. The specific net work and efficiency of a precooled cycle have been calculated and compared to the conventional systems. It has been concluded that the precooling has a marked effect on the specific net work and efficiency at low temperature ratio. Also without increasing the maximum cycle temperature the precooled cycle can work at a higher compressor pressure ratio and at higher temperature ratio. |
