The present invention further relates to a mechanism for removing debris from the produced water disposal apparatus. In one embodiment, heat is supplied from an externally operated combustion system, rather than the submerged combustion. In one embodiment, the apparatus provides a concentrator, in which a solute can be removed and recovered from an aqueous medium containing the solute.

The present invention is directed to an apparatus for directing steam, hot water or hot water vapor and hot air onto a target area, the apparatus comprising a water container and a fuel container connected and supplying water and fuel to an applicator wand with an applicator head which generates steam and heat for application adjacent to the target area of application to the unwanted vegetation. Steam is generated immediately adjacent to the target area within the applicator head and combined with surplus heat from the steam generation process to produce heated steam and water vapor for application to the target area. In a preferred embodiment of the invention, the applicator wand is hand held, the applicator head having an inlet, an outlet and a body therebetween, the water and fuel being supplied to a steam generator and burner within the body of the applicator head which generates steam and hot air adjacent to the target area for application through the outlet to the target area.

A downhole steam generation system may include a burner head assembly, a liner assembly, a vaporization sleeve, and a support sleeve. The burner head assembly may include a sudden expansion region with one or more injectors. The liner assembly may include a water-cooled body having one or more water injection arrangements. The system may be optimized to assist in the recovery of hydrocarbons from different types of reservoirs. A method of recovering hydrocarbons may include supplying one or more fluids to the system, combusting a fuel and an oxidant to generate a combustion product, injecting a fluid into the combustion product to generate an exhaust gas, injecting the exhaust gas into a reservoir, and recovering hydrocarbons from the reservoir.

The surface area of the gas-side first portion may be greater than the surface area of the water-side first portion and the surface area of the gas-side second portion may be less than or approximately equal to the surface area of the water-side second portion.

A startup burner assembly for use in snow melting applications, and which permits initiation of snow melting without first supplying water as a coolant. The startup burner assembly comprises a fuel burner having adjustable combustion output and a nozzle to facilitate the emergence of products of combustion, and a combustion chamber having a first portion in substantially air-tight communication with the fuel burner and enclosing the nozzle and a second portion shaped and dimensioned for disposition into a snow melting receptacle or pit. The combustion chamber has a plurality of discharge holes formed at least on the second portion thereof to permit the egress of products of combustion from the fuel burner into the tank or pit, and thereby permit agitation and melting of snow loaded therein, The startup burner assembly also includes an air cooling assembly for supplying air to cool at least the first portion of the combustion chamber.

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.

The invention is about a submerged combustion method and the device; specifically, it is a submerged combustion method and the device utilizing turbine heat engine principle. In the invention, turbine power combustion means is used and substitutes the conventional submerged combustion system that must equip air blowing means. The high temperature gases generated from the combustion within the turbine power combustion means will do work on the turbine, which will drive the air compressor means of the turbine power combustion means to induce air for combustion, and will drive the second-time complete combustion of high temperature gases and the complement fuel, and then the gases will come out from water bottom against tank water pressure and carry out heat interchange with tank water. The turbine submerged combustion boiler device of the invention need not equip air blowing means which would consume additional energy. Thus, it has high energy efficiency and a simple system structure. Additionally, it has features of high heat interchange rate, stable long term heat efficiency, environmental protection, etc.

Embodiments of the present disclosure can include a system for generating steam. The system can include a direct steam generator configured to generate saturated steam and combustion exhaust constituents. A close coupled heat exchanger can be fluidly coupled to the direct steam generator, the close coupled heat exchanger can be configured to route the saturated or superheated steam and combustion exhaust constituents through an exhaust constituent removal system. The system can include an energy recovery system that reclaims the energy from the exhaust constituents.

The present invention relates to a heat exchanging type boiler that includes: a water retaining reservoir (10) in which a predetermined amount of water is charged; and a combustion chamber (33) for emitting heating gas at a high temperature to the water in the water retaining reservoir (10) through a heating gas supply pipe (20) such that the water in the water retaining reservoir (10) is raised to produce steam at a high pressure, the boiler characterized in that water discharging film (32) disposed between the heating gas supply pipe (20) and the water and having a plurality of fine through holes such taht the water in the water retaining reservoir (10) is not leaked to the combustion chamber (33) and at the same time the heating gas emitted to the water by means of the heating gas supply pipe (20) is distributed in substantially small bubble form. Thus, water heating speed can be considerably increased, heat efficiency of the boiler can be more improved, a volume of the boiler can be decreased, the life of the boiler can be semi-permanently extended since the water retaining reservoir is not directly heated, and the cleaning of the interior of the boiler can be carried out in an easy manner.
