Abstract
The set of a humid air turbine (HAT) operating without any aftercooler for the compressed air provides good conditions for the cogeneration of network heat because the temperature of the outlet gases is sufficiently high. The production of network heat does not decrease the amount of the produced electricity. The ratio of the annual production of electricity to the annual cogeneration of heat has been determined for optimal parameters of the HAT system, for given temperature characteristics of the network water and for various limiting values of the ambient temperature, which determine the beginning of the operation of the peak boiler. The attained cumulative economy of chemical energy and the reduction of the emission of CO 2 and NO x have been calculated. The specific cost of the produced heat has been evaluated and its dependence on the price of the sold electricity and on the value of the limiting ambient temperature have been determined.
