Abstract
A process and apparatus for oxygen-rich combustion wherein a first portion of about 5 to about 40 percent of the total fuel to be cracked and combusted is introduced to a cracking chamber where it is combusted and cracked at a temperature below about 2200.degree. F. to produce a cracked products mixture. Oxygen-rich gas of greater than about 30 volume percent oxygen is introduced to the cracking chamber in about 5 to about 50 percent of the stoichiometric requirement for complete combustion of the first portion of fuel introduced to that chamber. Cracked products mixture, a second remaining portion of fresh fuel and oxidizer having sufficient oxygen for substantially complete combustion of the combustible portion of the cracked porducts mixture and the fresh fuel are introduced to a combustion chamber wherein the combustible portion of the cracked products mixture and the fresh fuel are combusted. The process and apparatus provide continuous operation of a fuel cracking chamber when used with regenerative furnaces, such as in the glass making industry.
