The present invention relates to a method of combusting a fuel gas with a stoichiometric or near stoichiometric amount of molecular oxygen in the presence of a controlled amount of a diluent to enhance the extent of combustion reactions in high heat transfer environment. The energy released is utilized to heat a fluid by direct contact with the flame. The diluent can be different from the fluid to be heated with respect to composition, temperature or pressure. The diluent can be same as or derived from the fluid to be heated.

Method for enhancing combustion reactions in high heat transfer environments

Flame stability of a burner that is operated with a mixture of oxygen and flue gas as the oxidant, is enhanced by including a second burner that combusts fuel with oxidant having a high Ocontent.
