Hydrocarbon fuel reformer suitable for producing synthesis hydrogen gas from reactions with hydrocarbons fuels, oxygen, and steam. A first tube has a first tube inlet and a first tube outlet . The first tube inlet is adapted for receiving a first mixture including an oxygen-containing gas and a first fuel. A partially oxidized first reaction reformate is directed out of the first tube into a mixing zone . A second tube is annularly disposed about the first tube and has a second tube inlet and a second tube outlet . The second tube inlet is adapted for receiving a second mixture including steam and a second fuel. A steam reformed second reaction reformate is directed out of the second tube and into the mixing zone . From the mixing zone , the first and second reaction reformates may be directed into a catalytic reforming zone containing a reforming catalyst

Apparatus for converting hydrocarbon fuel into hydrogen gas and carbon dioxide

A method and apparatus for controlling the operation of a burner apparatus are provided via the flame intensity of combustion reaction mixtures of oxidant and fuel gas.

Burner control

A hydrocarbon fuel reformer (,) is disclosed suitable for producing synthesis hydrogen gas from reactions with hydrocarbons fuels, oxygen, and steam. The reformer (,) comprises first and second tubes (,). The first tube (,) includes a first catalyst (,) and receives a first mixture of steam and a first fuel. The second tube (,) is annularly disposed about the first tube (,) and receives a second mixture of an oxygen-containing gas and a second fuel. In one embodiment, a third tube (,) is annularly disposed about the second tube (,) and receives a first reaction reformate from the first tube (,) and a second reaction reformate from the second tube (,). A catalyst reforming zone (,) annularly disposed about the third tube (,) may be provided to subject reformate constituents to a shift reaction. In another embodiment, a fractionator is provided to distill first and second fuels from a fuel supply source.

A hydrocarbon fuel reforming method is disclosed suitable for producing synthesis hydrogen gas from reactions with hydrocarbons fuels, oxygen, and steam. A first mixture of an oxygen-containing gas and a first fuel is directed into a first tube,to produce a first reaction reformate. A second mixture of steam and a second fuel is directed into a second tube,annularly disposed about the first tube,to produce a second reaction reformate. The first and second reaction reformates are then directed into a reforming zone,and subject to a catalytic reforming reaction. In another aspect of the method, a first fuel is combusted with an oxygen-containing gas in a first zone,to produce a reformate stream, while a second fuel under steam reforming in a second zone,. Heat energy from the first zone,is transferred to the second zone
