A low emission and environmentally friendly apparatus and method is used to generate a high pressure stream of thermal vapor. The thermal vapor stream may be injected into a subterranean formation for recovery of highly viscous petroleum or used to turn a steam turbine for driving an electrical generator. In one implementation, the high pressure stream of thermal vapor is generated by burning a high temperature fuel, including any short or long chain hydrocarbon products from methane to coal, in an enclosed vessel to produce combustion gases. Various techniques may be used to improve heat distribution and lower the temperature of the combustion gases. Water may be used to quench the combustion gases and produce the superheated steam or vapor. The water may be introduced onto the combustion gases by spraying, weeping, dripping, and the like.

Methods and systems generate steam and carbon dioxide mixtures suitable for injection to assist in recovering hydrocarbons from oil sands based on concentration of the carbon dioxide in the mixtures as influenced by temperature of water introduced into a direct steam generator. Increasing temperature of the water to above 200° C. before introduction into the direct steam generator may utilize heat from an electrical power generation unit. Enthalpy of this preheated water impacts amount of fuel needed to burn in the direct steam generator and hence the concentration of the carbon dioxide, which may be below 11% by mass percent of the steam.

An efficient high-temperature water vapor generator is used to de-contaminate soil. 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 a vapor tube (which has openings for emitting the vapor), thereby heating the vapor tube to temperatures of 800° F. or greater. A soil tube having lifting paddles located therein surrounds the vapor tube. Contaminated soil enters one end of the soil tube. The soil tube is rotated, thereby moving the contaminated soil into contact with the vapor tube (decontaminating the soil). The lifting paddles move the soil toward the second end of the rotating soil tube.
