POWER PLANT Russian patent published in 2006 - IPC F02G5/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to plants designed for self-contained supply of consumers with electric energy and heat in cases when they cannot be supplied with power and heat from external power system. Proposed power plant designed for combined generation of electric energy and heat has electric generator driven by internal combustion engine with systems of cooling of engine oil, cylinder block, supercharging, and exhaust system. Each system contains heat exchanger-heat recoverer. Engine oil cooling system is placed between first output of engine and its first input, cylinder block cooling system is connected between second output and second input of engine, supercharging system is connected to third input of engine, and exhaust system is connected to third output of engine. Heat exchangers-recoverers of supercharging and engine oil cooling systems are connected in tandem to engine cylinder block cooling system. Temperature control valve provided with one input and two outputs is placed in engine cylinder block cooling system between second output of engine and heat exchanger-recover. Input of temperature control valve is connected to second output of engine, and its first output is connected with heat exchanger-recoverer of cylinder block cooling system. Plant is furnished with additional heat exchanger connected between heat exchangers-recoverers of supercharging system and cylinder block cooling system. Circulating pump is placed between additional heat exchanger and heat exchanger-recoverer of supercharging system. Output of circulating pump is connected with heat exchanger-recoverer of supercharging system and input of circulating pump is connected with additional heat exchanger to which second output of temperature control valve is connected. Additional heat exchanger is provided with positive cooling system with drive furnished with control unit connected with temperature transmitter of cylinder block cooling system.

EFFECT: provision of required cooling of internal combustion engine under any operating conditions, improved efficiency and reliability of plant.
