Gap passes through；Heat exchange occurs with cobblestone, cobblestone is made to heat up.And the heat-preservation cotton coated by tank wall is kept the temperature, and reduces heat
Amount loss.At night or rainy days, with conduction oil heat exchange occurs for cobblestone, and conduction oil is made to heat up, makes steam generator
Continue to generate electricity.
Go out the setting of cold oil above tank body into deep fat lower section, be conducive to efficiently using for solar energy, ensure conduction oil outlet
The conduction oil that pipe extracts is that tank body temperature is highest, i.e. the conduction oil after solar energy heat collector heats, directly on the top
It is taken away by steam generator, reduces the loss of energy, and the effect of daily solar power generation because of the setting of energy storage canister, will not be affected
Rate.And at night or rainy days, after with conduction oil heat exchange occurs for prefabricated mixed mud storage body, by heat conduction after deep fat rising
Oil export pipe is taken away, generates electricity into steam generator, reduces the unnecessary heat-energy losses during storage.
