AUTONOMOUS MULTIFUNCTIONAL POWER PLANT Russian patent published in 2012 - IPC F02G5/04 F02G1/43 

FIELD: power engineering.

SUBSTANCE: power plant for generation of thermal and electric energy comprises a Stirling engine 1 with a power generator 5 on one shaft, a heat exchanger - utiliser of spent gases of the engine, a cooling system 3 and a line 11 of main water with a valve. The cooling system 3 is connected via a heat exchanger 9 with a system of external heat supply. The heat exchanger - utiliser of spent gases of the Stirling engine is made in the form of a vortex heat generator 6. Inside the heat generator 6 there is a manifold of engine spent gases 4 arranged coaxially. The heat exchanger 9 of the cooling system manifold 7 is connected to the system of the external heat supply with the first line directly, and with the second line - via the vortex heat generator 6. The heat generator 6 comprises a speeding device, a swirler (a cyclone), a vortex pipe and a brake - heat exchanger. The brake - heat exchanger is made in the form of perforated parallel plates rigidly installed in the space between the spent gas manifold 4 and the inner diameter of the vortex pipe. At the outlet of the vortex heat generator 6 there is a condensing chamber 17. In the cooling system manifold 7 there is a control valve 18.

EFFECT: higher heat efficiency, reduction of heat losses and simplified design.
