Abstract

In the current study a combined heat and power (CHP) system based on DIESEL ENGINEs is studied. After modeling the different components of a CHP system, the system is investigated parametrically according to first and second laws of thermodynamics. In this investigation instead of modeling the air standard cycle, the fuel air standard cycle and fuel combustion are simulated, which leads to more accurate results. However, a standard cycle has many differences with an actual cycle, and therefore the results of its analysis will be, to some extent, different from the results of analyzing the corresponding actual cycle. Therefore, the exhaust gas from combustion chamber of a DIESEL ENGINE is also used to simulate the CHP system, and the heat exchanger of the CHP is investigated from exergetic and economic viewpoints. It was seen that, applying the pre-described system, it is possible to warm up 0.17kg/s water from 25°C to 68.64oC. This enhances the overall efficiency of the system about 20%, raising it up to 80%. EXERGY destruction in heat exchanger is slightly high which is due to heat transfer process and high temperature difference in the heat exchanger.
