Abstract
This paper describes the performance of thermal storage integrated micro-cogeneration system based on single cylinder diesel engine. In addition to electricity generated from genset, waste heat from hot exhaust of diesel engine was used to heat water in a double pipe heat exchanger of 67.70Â cm length with inside tube diameter of 3.81Â cm and outside tube diameter of 5.08Â cm. Additionally, a latent heat thermal energy storage system was also integrated with this cogeneration system. A shell and tube type heat exchanger of 346Â mm diameter and 420Â mm height with 45 tubes of 18Â mm diameter each was designed and fabricated, to store thermal energy, in which Erythritol (C4H10O4) was used as phase changing material. The test results show that micro capacity (4.4Â kW), stationary, single cylinder, diesel engine can be successfully utilized to simultaneously produce power as well as heating, and to also store thermal energy. Slight decrease in engine performance was observed when double pipe heat exchanger and latent heat thermal energy storage system was integrated with engine but the amount of energy which could be recovered was significant. Maximum percentage of energy saved was obtained at a load of 3.6Â kW and was 15.2%.
