Specific embodiment
As shown in Figure 1, boiler of organic heat carrier, including solid heat storage device, the high temperature oil pump circulatory system and hot water circuit
System, the high temperature oil pump circulatory system include filling pump 1, oil circulating pump 2, boiler tube 3 and safety valve 6, and boiler tube 3 is vertical using snakelike S shape
It is fitted closely to setting with magnesium iron gitter brick, conduction oil is directed by filling pump 1 in magnesium grey iron block accumulation of heat heap 4 between left and right away from interior
The high temperature oil pump circulatory system is directed at boiler tube 3 by oil circulating pump 2 and is inscribed received heat, conduction oil from bottom to top most end form in boiler tube 3
At access, it is introduced into lower layer's thermal storage unit, due to the different difference of accumulation of heat heap upper and lower level Temperature Distribution height, conduction oil can be with
It is first preheated in lower layer's thermal storage unit, upper layer thermal storage unit is entered after heating, can so prevent conduction oil from heating up
Lead to the consequence of bad expansion and gasification fastly, the high temperature heat conductive oil for having absorbed heat, which enters in heat exchanger 8, to exchange heat, and changes
Conduction oil after heat is again introduced into the circulatory system and is heated, and solid heat storage device includes magnesium iron accumulation of heat heap 4, baffle heater 5
