Description
Technical field
The present invention relates to solar electrical energy generation, particularly with the system of generating of distributed heat accumulating type and Poly-generation.
Background technique
It is the working medium generating that existing generation technology mainly adopts steam, promptly logical overheated machine principle, generated electricity by the steam heat of the restriction of Carnot's cycle, main working medium is a water, its nozzle is arranged on the stator, do not move, blade is arranged on the rotor, and the steam of nozzle ejection promotes blade and is rotated generating.
Adopt the organic Rankine cycle of low temperature (ORC) generator set, be suitable for low-temperature heat source and small-sized generating, but it still is the hot machine of Carnot's cycle, be with existing large-scale steam generating equipment miniaturization, its nozzle and blade setting and large-scale identical, such structure setting has been limited the using energy source of generating, and working medium also must adopt the working medium of low temperature.
In addition, Stirling-electric hybrid also is a kind of power generating equipment, and the piston that it mainly adopts cylinder body and motion utilizes the heat energy of cylinder body outside to realize the working medium of cylinder interior is vaporized, and drives power generating equipment behind the promotion movement of cylinder block and carries out unit generation.Its essence also is hot machine principle.
