Abstract
A process and apparatus for combustion of a fuel and oxidant in which a first portion of a fuel is mixed with an oxidant to form a fuel-lean fuel/oxidant mixture in a fuel-lean combustion zone. The remaining portion of fuel is mixed with the fuel-lean fuel/oxidant mixture downstream of the fuel-lean combustion zone, forming a substantially stoichiometric fuel/oxidant mixture. The stoichiometric fuel/oxidant mixture is ignited, forming a primary flame having high luminosity and low NO.sub.x emissions.
