Abstract: In the 7-th decade of the previous century it was designed the new power station for Timisoara Romania. It was predicted to work with lignite. As load fuel and sustain of flame fuel it was approved natural gas. The initial profile of the Power Heating Station was: 2×120/150 MW turboalternator groups; for industrial consumers 3×100 t/h steam boilers with 250 ºC and 15 bar; thermal central for start steam boiler comprizing 4×10 t/h steam boiler with 300 °C and 16 bar. The main thermal agent, hot water for district heating of the town had to be prepared in 2×100 Gcal/h (2×116 MW) hot water boiler. During the power station construction, the consumers for 250 ºC and 15 bar steam were no more, or they have changed their production structure. In 1988 began the thermal production of the new Heating Station/Plant, and only for hot water. After 1990 the finances for 2×120/150 MW groups were stopped and their construction also. As the hot water prepared in 2×100 Gcal/h hot wa!
ter boilers was not enough for district heating of the town, the steam pressure was reduced from 15 to 6 bar, its temperature also and using heat exchangers the Heating Plant could deliver more hot water for district heating of the town. So other 225 Gcal/h (261 MW) were produced. The paper presents the solution for Heating Plant in order to produce enough hot water, electric energy for inner consumption being assured in the same time. Also, the effects on environmental protection and on the heat market in system are analized.
