TECHNIQUE OF THE CHOICE OF THE VARIANT OF RECONSTRUCTION STEAM OF TURBINE THERMAL POWER STATIONS WITH PHYSICALLY WORN
OUT EQUIPMENT
One of problems of increase of efficiency of the central heating, caused in high percent of deterioration of the core and thermal power station auxiliaries is considered. The technique of a choice of a variant of reconstruction of stations with use gas of the turbine installations, considering local conditions and features of power supply of a city is offered.
Central heating, core and thermal power station, use gas of the turbine installations
