The possibility of the useful utilization of the heat carried by exhaust gases is restricted due to the acid dew point, which determines the allowed subcooling temperature. The two factors of physical exergy (b\({}_{\text{steam}}\)) and exergy coefficient of energy quality, which were calculated for the main turbine (MT) and the turbo alternator (TA) exhaust steam, indicate the high potential of this energy source. Nevertheless, the utilization of this heat in conventional plate and shell heat exchangers is not possible as a result of the low energy state as a consequence of the low temperature difference and considerable dispersion of that heat. In the conclusion of [2], it was pointed out that the obtained and presented results are technical hints indicating the rational utilization of the identified waste heat from the process of mixing fluxes. In conclusion of previous research, a mathematical model of the regenerative steam jet injector was presented [1,2,4] as a solution for the useful utilization of exhaust steam for turbines. The proposed suggestion assumed the use of steam jet injectors for mixing fluxes of low-pressure exhaust steam with bleed steam from the main turbine used as a drive medium for the injectors.
