6 Conclusion The benefits of utilising vast resource of low grade heat cannot be ignored provided that power can be recovered at an economic cost. Nowadays, ORC systems can be characterised as the only proven technology used in kW to 1 MW range, despite the fact that it is linked with low efficiencies. In practice limitation of the overall cycle efficiency can be partly explained by the low temperature of the heat source, low off design expander efficiency, lack of insulation and high condenser pump/fan power consumption. ORC offer a simple cycle design, enables unattended operation, reduce production cost and complexity. It has to be noticed that such a unit performs well only as long as the characteristic of the heat source is similar to the one it was designed for. The main goal of this research was to simulate and calculate the design operation of an ORC system. In the course of the research work conducted, a semi-empirical model based on the conservation of mass and energy for each component was designed and created with which thermodynamic analyses were carried out. On the basis of the design parameters for optimal performance and system sensitivity, numerous simulations were carried out to investigate the complex interrelationships and influence on cycle efficiency and net power. Brazed-plate heat exchanger was found to be the most suitable technology for boiler since it presents compact design, high heat transfer coefficient and acceptable cost. In the power industry, the reduced availability of water as the cooling medium, combined with an increased emphasis on environmental considerations, often makes the selection of a dry air type cooling tower a viable alternative to the traditional surface condenser. Optimization of the working conditions is also needed in order to reduce the expander supply superheating and the condenser exhaust subcooling. Dry fluids in general generate superheated vapour at the exit, and this reduces the area of net work in the T-s diagram. Hence, organic fluids should be operated at saturated conditions to reduce the total irreversibility of the system. The maximum value of total heat recovery efficiency increases with the increase of the inlet temperature of the waste heat and decreases by using working fluids of the lower critical temperature. The condensation pressure of the cycle is preferred to be higher than the atmospheric pressure. With sensitivity analysis it was also shown that the thermal efficiency of ORC increases when the condenser temperature is decreased or when the maximum cycle pressure is increased. 94PDF Image | study of ORC with the expansion process twin screw machines
