A method for using untreated produced water to generate steam and simultaneously producing diluents is disclosed. The method includes a combustion process for generating steam for hydrocarbon recovery using untreated water and, an optional process for recovering combustion byproducts to assist in hydrocarbon recovery or solvent injections. Specifically, a novel combustion method and a double-tube heat exchanger are used to generate steam while minimizing or eliminating water treatment steps and boiler fouling. Low value pitch, also known as asphalt, is used for combustion fuel. In addition to the steam generation, byproducts of the combustion process can be utilized in solvent injections or as a diluent.

This invention provides a system and method for efficiently and completely combusting oil in mixture with particulate solids. A furnace (kiln) having a feed nozzle with a lead screw drives the mixture from a feed hopper. This nozzle includes forced-air jets/ports at its tip providing makeup air and allowing atomization of the mixture. The nozzle thereby directs the mixture into a rotating combustion chamber that is tilted downwardly from the front toward a solid waste outlet port at the rear. Uncombusted fuel and air backflow to an upper, secondary chamber near the primary chamber front, and are completely combusted at a high temperature. Gasses exit a flue that can include a heat exchanger. This heat exchanger can be operatively connected to a heating device or other mechanism that converts the heat into usable energy. The nozzle can include a cone with axially tilted air ports about its perimeter.

Methods and apparatus to automatically control oil burning operations are disclosed. An example apparatus includes a first control valve to control a flow of a first fluid into a fluid mixture to be burned; and a second control valve to control a flow of a second fluid into the fluid mixture. The example apparatus further includes a meter to monitor a property of the fluid mixture in substantially realtime, the property indicative of a flammability of the fluid mixture, at least one of the first control valve or the second control valve to be automatically adjusted based on a measured value of the property of the fluid mixture

A high-temperature pyrolysis incineration apparatus that forces external air to a combustion chamber while burning an incineration processing material injected therein at a high temperature within a combustion chamber is provided. The apparatus includes an air-supply tube disposed at the center of the combustion chamber, a fuel supply pipe installed at an upper edge of the inside of the combustion chamber, a punching plate disposed at the bottom of the combustion chamber, a stirring rod rotatably installed at an upper surface of the punching plate using the air-supply tube as a fixing shaft, a heat recovery device disposed outside of the combustion chamber, and a circulation pipe extending from a lid of the combustion chamber to the outside that returns to a location corresponding to an upper portion of the stirring rod at a wall of the combustion chamber via the inside of the heat recovery device.

A well test burner system has a plurality of burner nozzles supported by a support structure. Each burner nozzle has an air inlet, a well product inlet and an air/well product mixture outlet. At least one of the burner nozzles is supported to pivot relative to the support structure while the burner nozzle is operating to expel air/well product mixture.

A toxic waste incinerator is capable of enhanced combustion of hazardous waste (oil contaminated sand, human waste, garbage, etc.) utilizing immersed non-combustible and thermally conductive objects for increasing heat feedback from the flames to the unburned fuel, while air inlets are used to optimize the air entrainment rate to enhance the burning efficiency. The burning rate of a fluidic mass such as a sand-oil mixture is enhanced using immersed conductive objects (copper rods) which enable rapid heat-up of the flame exposed to the upper surface of the rod and transmits heat back into the sand. Consequent conduction of heat to the porous media through the lower portion of the immersed rod significantly increases vaporization and therefore the burning rate. Incineration may be performed on a transient, exigent basis as with hazardous waste and oil spills, or as part of a permanent fixture for receiving an ongoing waste stream.
