[ I claim:] [1.] A method for combusting low heating value liquid comprising:(A) passing, in a stream having an axial direction, low heating value liquid, having a heating value less than 10,000 BTU/lb., into a combustion zone through a nozzle with at least some of the liquid being passed into the combustion zone at an angle greater than 35 degrees from said axial direction;(B) passing medium velocity oxidant into the combustion zone spaced from the low heating value fluid stream at a velocity within a range of from 100 to 300 feet per second, and creating a toroidal vortex within the combustion zone between the low heating value liquid stream and the medium velocity oxidant;(C) passing low heating value liquid and medium velocity oxidant into the toroidal vortex; and(D) carrying out combustion within the toroidal vortex.
