The coefficient of efficiency of the conversion of heat into mechanical work is a very important parameter for heat engines. We must therefore ensure that the primary conversion of the fuel's internal energy into heat is performed at the highest possible efficiency. In steam boilers, part of the low-temperature output heat of flue gases is returned into the combustion process when used for preheating the combustion air in air heaters, thereby increasing the boiler's efficiency. The air heaters used for large plants are usually Ljungström rotary regenerators, which are characterised by a certain degree of leakage and mixing of air flows and flue gases. This paper deals with the influence of leakage in an air heater and the influence of the amont of combustion air heated in an air heater and in a boiler itself are studied. The theoretical explanation is supported with the results of measurements on air heaters in a thermal power plant.
