摘要： An oil recovery process entails recovering an oil-water mixture from an oil bearing formation and separating the oil-water mixture to produce an oil product and produced water. The produced water includes suspended and dissolved solids and is subjected to treatment which removes suspended and dissolved solids therefrom. The treated water is then directed to a forced circulation steam generator that includes a furnace having a burner, water cooled walls and an evaporator unit. The treated water is pumped through the water cooled walls and the evaporator unit. The water passing through the water cooled walls and evaporator unit are heated to produce approximately 10% to approximately 30% quality steam in both the water cooled walls and the evaporator unit. The steam is collected and separated from a water-steam mixture to produce high quality steam, on the order of 95% or greater quality steam. This steam constitutes injection steam which is injected into an injection well to facilitate the recovery of the oil-water mixture.

The burner includes a burner case partitioned into a combustion chamber and a gas introduction chamber by a partition plate and a plurality of combustion tubes arranged in the combustion chamber. An air supply opening for supplying air into the gas introduction chamber is provided in the burner case. The partition plate has a plurality of opening portions communicating with the inside of the combustion tubes and a plurality of through holes communicating with the outside of the combustion tubes within the combustion chamber. The air supply opening is constructed to have an opening area smaller than the total sum of the total of opening areas of the plurality of opening portions and the total of opening areas of the plurality of through holes.

摘要： Modern steam generators typically include a radiant section and a convection section. Due to differing performance requirements of the radiant and convection sections, the radiant section often has a round cross-section, while the convection section often has a rectangular cross-section. Previous designs utilized a target wall to effect the transition. An angled transition section is disclosed herein that substantially eliminates the target wall and/or the reverse target and provides a corresponding improvement in steam generator efficiency.

摘要： A fluid heater constructed of rectangular tubing through which fluid to be heated is circulated in a circuitous path. The floor and walls of a combustion chamber of the heater are constructed of the rectangular tubing. A tubular coil stack is positioned over the combustion chamber and surrounded by coil stack chamber walls constructed of the rectangular tubing. Consequently, all surfaces of the fluid heater exposed directly to flame are constantly cooled by the fluid to be heated. A combustion unit of the fluid heater is removable to facilitate maintenance.
