Patent number: 8727767Abstract: An apparatus for continuation of combustion with a combustion apparatus when the supply of the normal operating oxidant or normal operating fuel is disrupted, or temporally reduced. Air or oxygen enriched air or oxygen and a gaseous fuel or a liquid fuel or both a gaseous and liquid fuel are introduced into the combustion apparatus in place of the normal oxidant-fuel mixture to effect combustion and maintain the heating level in the furnace. A burner capable of firing in any one of the following nine firing modes: Air-Gas; Air-Oxy-Gas; Oxy-Gas; Air-Oil; Air-Oxy-Oil; Oxy-Oil; Air-Oil-Gas; Air-Oxy-Oil-Gas; Oxy-Oil-Gas.Type: GrantFiled: January 15, 2010Date of Patent: May 20, 2014Assignee: Air Products and Chemicals, Inc.Inventors: Matthew James Watson, Douglas Jay Strange, Joseph Keith Juretus, Kevin Alan Lievre

Patent number: 8512033Abstract: A burner includes separate fuel and oxidant conduits. The fuel conduit has inlet, transitional, and outlet sections, and the oxidant conduit has inlet and outlet sections. The burner has a longitudinal axis and including a burner tip having a first elongated edge adjacent a flow of the fuel, and a second elongated edge adjacent a flow of an oxidant and forming a primary tip angle (?) of less than about 15° from a line parallel to the longitudinal axis and intersecting an upstream surface parallel to the longitudinal axis. The first elongated edge and the second elongated edge form a secondary tip angle (?) greater than the primary tip angle (?) and less than about 90° from a line tangent to and extending from the first elongated edge in the direction of the flow of the fuel.Type: GrantFiled: May 4, 2007Date of Patent: August 20, 2013Assignee: Air Products and Chemicals, Inc.Inventors: Mark Daniel D'Agostini, Kevin Alan Lievre

Patent number: 6524097Abstract: Method and apparatus for continuation of combustion with an oxy-fuel combustion system when the supply of oxygen is temporally reduced or stopped. Air or oxygen enriched air and fuel are introduced into the device being heated in place of the oxy-fuel mixture to effect combustion and maintain the heating level in the furnace. Water cooling of the furnace gases is used to reduce the volume of exhaust gases when operating in the air or oxygen enriched air mode.Type: GrantFiled: March 9, 2001Date of Patent: February 25, 2003Assignee: Air Products and Chemicals, Inc.Inventors: Bryan Clair Hoke, Jr., Aleksandar Georgi Slavejkov, Mark Daniel D'Agostini, Kevin Alan Lievre, Joseph Michael Pietrantonio

Patent number: 6519973Abstract: A process and furnace for melting glass is set forth wherein the majority of the combustion energy over the melting zone of the furnace is provided by oxy-fuel combustion while a majority of the combustion energy over the fining zone of the furnace is provided by air-fuel combustion. In many cases, it will be preferable to provide greater than 70% and up to and including 100% of the combustion energy over the melting zone by oxy-fuel combustion and greater than 70% and up to and including 100% of the combustion energy over the fining zone by air-fuel combustion. By proper tailoring of the combustion space atmosphere through oxy-fuel and air-fuel firing, the present invention can result in an improvement in glass productivity and quality. The present invention can be applied in the construction of a new furnace or can be applied to existing air-fuel furnaces.Type: GrantFiled: March 23, 2000Date of Patent: February 18, 2003Assignee: Air Products and Chemicals, Inc.Inventors: Bryan Clair Hoke, Jr., Kevin Alan Lievre, Aleksandar Georgi Slavejkov, Julian Leonard Inskip, Robert Dean Marchiando, Robert Michael Eng
