A COMBINED HEAT AND POWER SYSTEM

摘要

A combined heat and power system comprising a Stirling engine ( 1 ) the head ( 2 ) of which is heated by a burner. A heat exchanger ( 10 ) absorbs heat from exhaust gases from the burner which have heated the engine head. A supplementary burner ( 22, 23 ) generates additional heat which is directly absorbed by the heat exchanger. The supplementary burner is a multi-stage burner with separate stages ( 22, 23 ) which are independently controlled.
