Abstract
According to an embodiment, a burner system provides a flow of premixed fuel and flue gas, and combustion airflow is provided at an intended distal flame front position. The burner system may include a pilot burner. A burner system may include a pre-mix pilot burner. In an embodiment a main fuel may include a high hydrogen content.
Claims55
A method for operating a burner system comprising:
- mixing a gaseous fuel with flue gas as the gaseous fuel and flue gas travel from a proximal position to a distal position in a first mixing tube;
- providing a flow of combustion air through a second mixing tube to a distal position in the second mixing tube;
- igniting the gaseous fuel and combustion air with a distal pilot burner;
- and
- holding a combustion reaction of the gaseous fuel and combustion air with a distal flame holder positioned to receive the flow of fuel and flue gas and the flow of combustion air at the distal position.
2 more elements
An industrial burner, comprising:
- a first mixing tube configured to carry flue gas and fuel to a fuel dump plane;
- a second mixing tube configured to carry combustion air to the fuel dump plane;
- a distal flame holder disposed to receive the flue gas, fuel, and combustion air from the first mixing tube and the conduit, and to hold a combustion reaction thereof;
- and
- a distal pilot burner configured to cause ignition of the combustion reaction.
2 more elements
An industrial burner, comprising:
- a first mixing tube configured to carry flue gas and fuel to a fuel dump plane;
- an air conduit configured to carry combustion air to the fuel dump plane;
- a distal flame holder disposed to receive the flue gas, fuel, and combustion air from the first mixing tube and the conduit, and to hold a combustion reaction thereof;
- and
- a distal pilot burner configured to cause ignition of the combustion reaction,
- wherein the first mixing tube and the air conduit are configured to provide a ratio of fuel to oxygen configured to support combustion at a distal location coincident with the flame holder and to prevent mixing of fuel and oxygen prior to output at the fuel dump plane.

A burner system, comprising:
- a first mixing tube configured to carry flue gas and fuel to a fuel dump plane;
- an air conduit configured to carry combustion air to the fuel dump plane;
- a distal flame holder comprising a V-gutter flame holder disposed to receive the flue gas, fuel, and combustion air from the first mixing tube and the conduit, and to hold a combustion reaction thereof;
- and
- a distal pilot burner configured to cause ignition of the combustion reaction.
