Abstract
The invention comprises a method and apparatus for burning combustible fluids, such as biofuel byproducts and feedstocks, which are difficult to burn in a stable and clean manner. The method includes preheating the combustion zone prior to initiating flow of the combustible fluid and maintaining a minimum oxygen concentration in the oxidant gas.
