Abstract
A flame holder system includes a support structure configured to support a plurality of burner tiles within a furnace volume. The support structure includes a frame supporting a support lattice. A number of burner tiles are arranged in an array on the support lattice. The support structure is configured to be assemblable without tools inside the furnace volume, using components that are sized to fit through an access port in a wall of the furnace.
Claims48
A system, comprising:
- a support structure configured to support a plurality of burner tiles within a furnace volume, the support structure including:
- a frame including frame members configured to be assembled on location;
- and
- a support lattice having a plurality of support members sized to span the frame and configured to be assembled on location with the frame;
- a flame holder, including the plurality of burner tiles configured to be assembled into an array on location, supported within the furnace volume by the support lattice;
- a furnace having a furnace wall extending around and defining the furnace volume;
- and
- a plurality of support brackets coupled to the furnace wall and extending into the furnace volume, the frame being supported within the furnace volume by the plurality of brackets.

A method, comprising:
- assembling a support structure inside of a furnace volume, including:
- assembling a frame inside the furnace volume,
- supporting the frame within the furnace volume, and
- assembling a support lattice on the supported frame;
- positioning each of a plurality of burner tiles on the support lattice;
- and
- separably arranging the plurality of burner tiles into an array on the support lattice;
- wherein the step of separably arranging the plurality of burner tiles into an array on the support lattice comprises reaching between the support members from below the support lattice and moving each of the plurality of burner tiles into a respective position in the array.
5 more elements
A system, comprising:
- a support structure configured to support a plurality of burner tiles within a furnace volume, the support structure including:
- a frame including frame members configured to be assembled by hand and fastened together without the use of hand tools;
- a support lattice having a plurality of support members sized to span the frame and configured to be assembled with the frame by hand and fastened together without the use of hand tools;
- and
- a flame holder including a plurality of bluff body burner tiles supported by the support lattice.
2 more elements
A system, comprising:
- a support structure configured to support a plurality of burner tiles within a furnace volume, the support structure including:
- a frame including frame members made entirely of refractory ceramic;
- a support lattice having a plurality of support members sized to span the frame, made entirely of refractory ceramic;
- and
- a plurality of connecting members configured to couple the frame members and the support members together, the connecting members being made entirely of refractory ceramic;
- wherein each of the plurality of connecting members includes a plurality of keyhole apertures, and ones of the frame members and the support members include features configured to lockingly engage corresponding keyhole apertures of the connecting members.
