Abstract: An efficient high-temperature water vapor generator includes a combustion chamber and a surrounding structure, wherein a cavity is located therebetween. Water is pumped into the cavity at a location near a first end of the combustion chamber. Water is removed from the cavity at a location near a second end of the combustion chamber, opposite the first end. The water removed from the cavity is injected into the combustion chamber at a location near the first end. Fuel and air are also introduced into the combustion chamber at the first end. The fuel and air are ignited near the first end of the combustion chamber, thereby creating high-temperature water vapor, and pre-heating the water in the cavity surrounding the combustion chamber.

Abstract: An efficient high-temperature water vapor generator is used to heat heavy oil located in an underground cavity, thereby reducing the viscosity of the oil and enabling the oil to be pumped to the surface. The vapor generator includes a combustion chamber and a surrounding structure, wherein a cavity is located therebetween. Water is routed through the cavity and into the combustion chamber, where water vapor and heat are generated in the presence of fuel, ignition and air. The generated heat pre-heats the water in the cavity, thereby creating an efficient system. The water vapor is forced into the underground cavity, thereby heating the oil located in the cavity.

Abstract: A low-pressure energy system is provided that includes a combustion chamber immersed in water within an insulated container. Low-pressure air flow is introduced into one end of the combustion chamber. Fuel, sparks and water are also introduced to the combustion chamber, thereby generating steam and heat. The steam is blown through the combustion chamber to a first radiator, which emits heat and a steam exhaust, which can be used to increase the humidity of the enclosure housing the energy system. The heat generated by the combustion chamber heats the water in the insulated container. The heated water is pumped through a second radiator, thereby extracting additional heat from the system. A fan may be configured to introduce air flow over both the first and second radiators, thereby further improving heat transfer to the ambient air. Water can optionally be omitted from the combustion chamber.
