Abstract:
1. A liquid vaporizer and a combustion chamber, comprising: a first body having a cross sectional shape and dimensions substantially equal to the cross sectional shape and dimensions of a cavity in a second body, thereby allowing the first body to be non-permanently inserted into the second body, wherein the outer surface of the first body, the inner surface forming the cavity in the second body, or both is modified to create a vaporization pathway between the first and second bodies when the surfaces mate; a vaporization pathway inlet for fluid comprising a liquid fuel; a vaporization pathway outlet for fluid comprising primarily vapor, the vaporization pathway outlet in fluid communication with the combustion chamber: and a heater in thermal communication with the first body, the second body, or both; wherein the heater actively controls the temperature of the vaporization pathway, the liquid fuel is vaporized prior to introduction into the combustion chamber, the temperature of the vaporization pathway is actively controlled as a substantially independent operating parameter, and oxidant gas flowing to the combustion chamber is preheated by flowing over at least a portion of the exterior of the combustion chamber.
