Increasing the operational efficiency of a heat engine plant through implementation of trigeneration

This paper discusses how to increase the efficiency of a plant by implementing a trigeneration solution. There have been analyzed two refrigeration technologies: compression and absorption. Since the purpose of the district heating plant is to use the heat engines to produce as much electricity as possible, which will further be sold, and to utilize the available thermal energy, the implementation of an absorption trigeneration solution has been proven to be viable. The analysis of the load duration curves showed a thermal potential of approximately 2.9 MW that could be used in an absorption installation for the production of cold. The resulting amount of cold is about 1.7 MW and will be used in a vegetable and fruit storehouse near the plant to keep the temperature in the range of 4-6 ° C.
