Abstract
The aim was to find methods for the determination of efficiency grades in relation to smaller decentral gas-motor driven cogeneration plants. In the long run the aim was also to be able to continuously determine the combustion values of gaseous fuels derived from straw, sanitary landfills and air cleaning systems. Determination of efficiency grades for cogeneration plants is based on a knowledge of the input effect which is generally gained by measurement of fuel consumption and the fuels` combustion values. This process is expensive, especially as the quality of the fuel varies, as is the case with methane. The project involved the development of an indirect method of determination which does not involve the measurement of combustion values. An indirect method based on the use of the Rankine process used in relation to larger power stations was adapted to smaller cogeneration plants based on gas motors. The method was used on 5 natural-gas fired cogeneration plants and calculations showed that the indirect method gives an idea of the input effect which is more reliable than the direct method. It was also shown that the efficiency can be determined with a smaller degree of uncertainty. (AB).
