Power production in cogeneration units

The aim of this thesis is the technical-economic evaluation of the advantages of combined pruduction of electrical and thermal energy, depending on the current offer price of feed, bonuses and allowances.. There are described co-generational technologies and used for units with performance up to 500 kWe. There are discussed in detail cogeneration units based on reciprocating internal combustion engines. The thesis contents evaluation of various modes of operation of co-generation unit, depanding on the results is chosen the most suitable mode. Daily yield was calculated in relation with prices paid for commodities and service. Co-generational contribution were considered as well as contribution for decentralized production of electricity. From the operational and economical point of view the most effective mode of running the co-generation unit is 12 hours mode. The economical evaluation of input was made. If the operational mode of the unit would follow the suggested mode, the financial return of input would be in two years. With the correct operation the co-generation unit would generate the income about 21,8 mil. CZK
