Sažetak
Today, the district heating (DH) is often based on cogeneration power plants with steam turbines for combined heat and power production (CHP turbines and plants). As the heat is supplied as steam with the given parameters, so CHP steam turbines are realized with controlled steam extractions. In case of stage-wise heating of the district heating system water the entire heating is realized in a number of successively connected water heaters by steam extracted from the turbine. The aim of stage-wise heating is additional production of electricity, because the heating steam extracted for the first stage in the direction of system water flow has lower pressure than for the second stage. In this paper the results of determination of heat-supply operating regime with twostage heating of the system water for CHP turbine of 120 MW power (T-100-110/130-3) installed in Cogeneration Power Plants Zagreb (TE-TO Zagreb), obtained by means of original developed computer program, will be presented both in analytic form (by equations) and by means of diagrams.
