Abstract
A steam generator having substantial thermal capacity for producing high quality steam used primarily for downhole steam generation in tertiary oil recovery. Incorporated in the generator is a novel high pressure, high heat release combustor, utilizing high pressure gaseous fuel and compressed gas oxidizer such as air, wherein thermal and mechanical stresses on the combustor structure are controlled. A method for controlling combustion induced mechanical stresses on the combustor through fluid injection is also disclosed. Disclosed designs provide substantially increased combustor life in 'Downhole' Steam Generation service. The burner employs an ignition technique utilizing gaseous injection of a pyrophoric compound such as triethylborane (TEB).
