Stove 7 and heat regenerative system) in parallel, the water storage in the pressure vessel 11 of steam accumulator 1 accounts between the 50～90% of total measurement (volume), preferably
For 60%, 70%, 80%, the steam inlet pipe 12 of steam accumulator 1 and the outlet of the heat exchanger 4 of disc type solar energy system
Road is connected, and is controlled by high-pressure side internally piloted valve 120；The steam outlet pipe 13 of steam accumulator 1 is connected with main steam line 9
Logical, and controlled by low-pressure side internally piloted valve 130；Disc type solar energy system passes through the sun 21 irradiation absorption solar energy；
When solar energy steam supply sufficient (i.e. rich), its pressure signal pass to rapidly low-pressure side internally piloted valve 130 so as to from
Move and turn down, the flow of its low-pressure side internally piloted valve 130 is just the main steam line necessary flow of solar energy side, by superfluous height
Pressure steam is sprayed in water by steam jet ejector 14, after the latent heat of vaporization is released in condensation, so that the water temperature in pressure vessel 11 is gradually risen
Height, the steam pressure in pressure vessel 11 improves therewith, and water level also rises therewith, completes the charging process of steam accumulator 1；
When the sun 21 radiation energy reduces suddenly, during for QI-insufficiency, then because the effect of pressure signal makes low-pressure side internally piloted valve

The combined cycle of electric system, provides for steam accumulator 1 simultaneously and fills heat.When solar energy supply is rich, its pressure signal is rapid
Pass to low-pressure side internally piloted valve 130 so as to automatically turn down, its valve flow is just the required stream of solar energy side main steam line
Amount, and the high steam of the surplus that heat exchanger 4 produces sprays into water by the steam jet ejector 14 being installed in pressure vessel 11
In, after the latent heat of vaporization is released in condensation, so that the water temperature in pressure vessel 11 is gradually risen, the steam pressure in pressure vessel 11 is therewith
Improve, water level also rises therewith, and complete steam accumulator 1 fills heat；Second endless form is disc type solar energy system, steam
Thermophore and the combined cycle of coal generating system, when solar radiant energy reduces suddenly, during for QI-insufficiency, then due to pressure signal
Effect make low-pressure side internally piloted valve 130 aperture increase, the rapid flash evaporation of superheated water, produce indirect steam, to supplement solar energy
The deficiency of system side air demand, reduced pressure in pressure vessel 11, water level reduces, and completes the heat release of steam accumulator 1.
