THERMODYNAMIC MODEL OF THE GAS AND STEAM PROCESS WITH COMBINED HEAT AND POWER PROCESS

A whole sequence of the parameters of the combined heat and power syst em (KWK) is described which enables a comparison between the electrici ty and heat demand of a consumer and the energy availability through a combined heat and power system. Proceeding from this, a thermodynamic model of a steam and gas process with combined heat and power is intr oduced which is based on an exergetic balancing of the subsystems of t he process. In this way, the varying thermodynamic quality of the ener gy flows occurring in the process will be taken into consideration so that the results of the model correspond in any case with the second L aw of thermodynamics.
