This contribution presents the analysis of possible utilizing of a small cogeneration unit for effective production of electricity, heat and process steam. A cogeneration unit (CHP) offers more effective utilizing of primary energy sources in comparison with separate production of electricity and heat. The studied poly-generation system consists from a cogeneration unit based on a stroke engine technology connected with an absorption cycle and a low-pressure steam generator. Low- pressure steam is led to a compressor for achievement of required steam pressure. Natural gas is considered as the most common primary energy source utilized in small-scale cogeneration units. The presented analysis respects technical parameters of a nowadays cogeneration units and synthesizes technical requirements for production of hot water, electricity, cool and process steam. This paper focuses on environmental benefit and technical assessment of presented ply-generation systems applicable in small- and mid-size technological processes.
