Analysis of the Actual Technical and Operational Parameters of Gas Cogeneration Sets with Combustion Engines

The present paper is the result o f the author's research project no. 4 T12D 030 28 on the "Analysis o f the actual technical and operational parameters of gas CHP sets" carried out by him in the years 2005-08, and financed by the Ministry o f Science and Informatizati on in Warsaw. The primary scientific o bjective of th e Project was to establish, compare and analyze the actual values of basic technical, operational and economi c parameters for different CHP (Combined Heat and Power) sets driven by gas piston engin es, operated in Poland. An analysis of the techniques of fuel gas uti lization in pi ston engine-driven cogeneration sets, bein g currently used ( and also likely to be used in the future) , finding their application in combined energy management, has been made within the Project, and a review of the operational conditions of a dozen or so CHP sets operated in Poland, fed by biogas, mine gas from hard coal mine demethanization has been c arried out. The results of this analysis have been included in the present monograph which, in a ddition to the review o f the conditions of CHP set operation, provides conclusions that have also utility importance, and therefore can well be useful in making the optimal design of a combined energy system consisting of combustion heatand powergenerating sets.
