Abstract: The present invention provides a two phase heat generation system (10) having a primary pressure vessel (108), an, interior vessel (122) spaced from the primary pressure vessel (108) defining a water jacket cavity (124) and a combustion chamber (125), the water cavity (124) being in fluid communication with the combustion chamber (126), the combustion chamber (126) having a combustion burner (144) for controlling combustion, a delivery conduit (136) being in communication with the combustion chamber (126) for delivering gas and compressed air into the combustion chamber (126) and an outlet passage (164) being in communication with the combustion chamber (126) for delivering of a two phase product.

Abstract: The present invention provides a two phase heat generation system having a primary pressure vessel and an interior vessel spaced from the primary pressure vessel defining a water cavity and a combustion chamber, the water cavity delivering fluid into the combustion chamber, the combustion chamber having a combustion burner and flame arrestor for controlling combustion; an inlet port being in communication with the combustion chamber for delivering gas and compressed air into the combustion chamber and an outlet for delivery of a two phase product.

Abstract: A method and apparatus for the improved recovery of oil from porous sub-surface deposits such as tar sands comprising mining and drilling a well with upper and lower horizontal rectangular grids extending outward into the deposit and applying steam heat or super heated crude oil vapor through the lower grid and hot pressurized flue gas through the upper grid. The flue gas and steam or super heated crude oil vapor are produced in a generation facility that provides electricity for the installation from turbine generators, the crude oil for super heating being provided by an initial production from the deposit following flue gas injection. Steam condensate is recycled from the recovered oil to the generation facility thereby reducing the water requirements and environmental pollution, and, where super heated crude oil vapor is used, a portion of the produced crude is used for this purpose.
