Work, working medium turbine is identical with mode during conditioned area 1 with the working method of thermophore, but working medium turbine in such cases
The time of work is limited, because now high-temp waste gas does not flows into thermophore I14 or thermophore II32 heating working medium, finishes
After merit, the working medium of condensation will not be absorbed heat evaporation again, so the energy that working medium turbine can utilize in such cases is only under high-speed working condition
The part energy that thermophore stores, when the working medium in thermophore I14 or thermophore II32 persistently discharges acting to exhausting or pressing
Power is too low can not drive working medium turbine after, working medium turbine will quit work.
