A fluid-cooled through-port oxy-fuel burner for converting an air-fuel regenerator port from air-fuel combustion to oxy-fuel combustion and an associated furnace and method. The oxy-fuel burner is suitable for installing through a regenerator port neck. The burner has an elbow-like bend to accommodate the geometry of the regenerator port neck. The burner has a cooling fluid jacket, a fuel conduit, a first oxidant conduit, and optionally an oxidant staging conduit.

Through-port oxy-fuel burner

The invention comprises a method and apparatus for burning combustible fluids, such as biofuel byproducts and feedstocks, which are difficult to burn in a stable and clean manner. The method includes preheating the combustion zone prior to initiating flow of the combustible fluid and maintaining a minimum oxygen concentration in the oxidant gas.

Method and apparatus for oxy-fuel combustion

A method useful with oxy-fuel combustion and in a furnace which contains molten material, wherein either substoichiometric or superstoichiometric combustion and low velocity injection of fuel and primary and secondary oxidant in an oxy-fuel burner are carried out in an orientation which forms either a reducing or oxidizing atmosphere proximate the molten surface.

Furnace and process for controlling the oxidative state of molten materials

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.

Multi-mode combustion device and method for using the device

An oxy-fuel burner that co-fires liquid fuel and gaseous fuel to create a more luminous flame. The characteristics of a liquid fuel spray and the gaseous fuel and primary oxidant gas flows, as well as the geometry of the burner is adapted to shroud the liquid fuel from the primary oxidant until it exits a precombustor and to prevent the liquid fuel from contacting the walls of the precombustor.

Highly radiative burner and combustion process

An apparatus for combustion of a liquid fuel, such as an atomizer or burner, and an associated method using the apparatus for combusting an atomized liquid fuel. The apparatus for combustion has an outer conduit, an inner conduit and a spray tip. The spray tip has a mixing chamber for receiving a liquid fuel and an atomizing gas, and an orifice for discharging the liquid fuel and atomizing gas mixture as an atomized liquid fuel. The inner conduit has external fins where at least some of the external fins contact the inner surface of the spray tip.

Liquid fuel combustion process and apparatus

Method for processing an article comprising a mixed conducting metal oxide material, which method comprises (a) contacting the article with an oxygen-containing gas and reducing or increasing the temperature of the oxygen-containing gas; (b) when the temperature of the oxygen-containing gas is reduced, reducing the oxygen activity in the oxygen-containing gas; and (c) when the temperature of the oxygen-containing gas is increased, increasing the oxygen activity in the oxygen-containing gas.
