Patent number: 6955051Abstract: Steam generation apparatus and methods are presented that are dedicated to oxygen-enriched air combustion of a fuel, wherein the oxygen concentration of the oxygen-enriched air may range from just above 21 percent to 100 percent. One apparatus comprises an oxygen-enriched air preheater through which oxygen-enriched air flows and exchanges heat indirectly with flue gas, creating a preheated oxygen-enriched air stream. The apparatus further comprises a boiler having a radiant section and a convection section, and other heat transfer units adapted to handle reduced flue gas flow rate and higher temperature flue gases than comparable air/fuel combustion boilers, thus allowing a smaller heat transfer surface area, a more compact design and a higher efficiency.Type: GrantFiled: September 11, 2003Date of Patent: October 18, 2005Assignee: American Air Liquide, Inc.Inventors: Ovidiu Marin, Olivier Charon, Erwin Penfornis

Patent number: 6398547Abstract: An oxy-combustion firing configuration, process, and apparatus can reduce the consumption of oxygen and fuel in an oxy-fuel combustion processes. Processes in accordance with the present invention include operation of an automated logic control device which controls an oscillating valve and controller. The valve and controller are used to oscillate the fuel and/or oxygen supplied to individual burners in a furnace. The oscillating parameters, such as frequency, amplitude, duty cycle, and phase difference between individual burners and their stoichiometry ratio are set to initiate preferable oxy-combustion in that furnace. Selective burner placement in the furnace enables the formation of deflagration zones which can provide very intense heating and complete combustion.Type: GrantFiled: March 31, 2000Date of Patent: June 4, 2002Assignees: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges Claude, American Air Liquide inc.Inventors: Mahendra L.

Publication number: 20010018962Abstract: A heat exchanger useful for preheating oxidizing gases in a combustion process includes a shell having an inlet and an outlet for the ingress and egress of a first heat exchange fluid, such as a flue gas or preheated air. A first tube manifold couples an inlet end-cap to the first end of the shell. The inlet end-cap has an inlet for receiving a second heat exchange fluid, such as an oxidizing gas. In one embodiment, a second manifold couples an outlet end-cap to the second end of the shell. The second manifold includes an outlet tube therein extending from the second manifold through an outlet opening in the outlet end-cap. A tube bundle is disposed within the shell for transporting the oxidizing gas through the heat exchanger and is coupled to the first and second tube manifolds. The outlet tube collects oxidizing gas flowing through the tube bundle for discharge to a combustion system.Type: ApplicationFiled: January 23, 2001Publication date: September 6, 2001Applicant: American Air Liquide Inc.Inventors: Mahendra L.

Patent number: 6283747Abstract: The invention relates to a method for heating a furnace comprising at least one burner capable of operating on an oxidant the oxygen content of which can vary; in a first period (P1) the burner is supplied with practically pure oxygen so as to provide a large amount of energy for heating, in a second period (P2) the burner is supplied with an oxidant, the oxygen content of which can vary between about 100% and 21%, in a third period (P3), the burner is supplied with an oxidant, the oxygen content of which is minimal, and which corresponds to a pilot period which requires only a small amount of heating energy. This method makes it possible to optimize the use of the furnace according to the desired thermal performance and oxidant operating costs.Type: GrantFiled: September 20, 1999Date of Patent: September 4, 2001Assignee: L'Air Liquide, Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Thierry Legiret, Gérard Le Gouefflec, Thierry Borissoff, Olivier Charon
