Abstract
The purpose of this study is to evaluate the Performance of Diesel engines, gas engines, and gas turbines when used in a Total Energy System. To begin with, the history of cogeneration was studied, current literature and texts reviewed and companies which deal with these engines or turbines were contacted. Electricity and gas tariffs were obtained from the P.S.E.&G. Co. It was decided to consider an apartment complex of approximately 200,000 ft2 having peak heating and cooling loads of approximately 4.92 million Btu/hr and 2.93 million Btu/hr respectively for this analysis. The average electrical demand was 520 KW. Next the energy distribution of the prime-movers was determined. The cost analysis of the system showed that the gas engine represented the greatest economy netting a profit of $37,OOO per annum on a capital investment of $680,000, over the utility cost of $540,000 per annum to supply the some energy. The gas turbine showed a profit of $23,000 per annum, but the capital investment was higher. More savings are possible in the winter months than in the summer months, The cogeneration system is a very attractive idea. Coupled with other energy management programs, it can help drastically reduce energy bills.
