Abstract
A hot gas engine including an injector for introducing a mixture of air and fuel into the combustion chamber to heat the working medium which is circulated in a system of ducts. Fresh air for the combustion of the fuel is preheated in a heat exchanger by exhaust gases from the combustion chamber and conducted to the fuel injector. A heating system for passing a heat exchange fluid to a space to be heated surrounds the combustion chamber, and the heat exchange fluid is thus heated by heat exchange with the exhaust gases.
Claims3
A hot gas engine in combination with a combustion chamber for generating a heating medium to heat a selected space, comprising:
- a. injector means for injecting fuel into said combustion chamber;
- b. intake means for passing combustion air from the atmosphere to said injector means;
- c. means for passing exhaust gas from said combustion chamber in heat exchange relationship with said intake means;
- and
- d. passage means for passing a heat exchange fluid from an intake to an outlet to heat a selected space, said air passage means being disposed in heat exchange relationship with said air intake means and said combustion chamber.
