Co-generator utilizing micro gas turbine engine

A co-generator comprising:

• a co-generator housing having a shell and a inlet plenum and an exhaust diffuser formed in said shell;
• a micro gas turbine engine supported within said shell and including:
• an engine housing having a compressor chamber with an intake in fluid communication with said inlet plenum, a turbine chamber with an exhaust in fluid communication with said exhaust diffuser and a combustion chamber interposed between said compressor chamber and said turbine chamber to provide fluid communication therebetween;
• a compressor rotatably supported in said compressor chamber;
• a fuel system for injecting a fuel into said combustor;
• and
• a turbine rotatably supported in said turbine housing;
• and
• a heat exchanger assembly supported within said shell and including:
• a first fluid circuit in fluid communication with said exhaust diffuser;
• and
• a second fluid loop in heat transfer relationship with said first fluid circuit such that an exhaust gas flowing in said first fluid circuit heats an ambient fluid flowing in said second fluid circuit to generate a heated ambient fluid.
