The combustion through-flow section in room that expands is square, and wall is the heat storage of refractory material laying, and heat storage can be linear pattern or corrugated plating
Shape；Secondary air chamber is set around combustion room is expanded；The secondary air chamber entrance side is connected with secondary air channel, and secondary air channel is positioned at mixing
Device and expansion combustion room linkage section outside, secondary air chamber outlet is positioned at expansion combustion room end；The igniter is arranged on blender and fired with expanding
Room expanded type linkage section.
The training wall for expanding combustion interior and being provided with refractory material laying, the linear type of training wall or corrugated plate shape, water conservancy diversion
Wall central axial direction is level.The training wall be arranged in parallel more than two from top to bottom in expansion combustion interior.
In the technical scheme, non-return body is taper.
Compared with prior art, the beneficial effects of the utility model are：1st, low boiling fuel and First air are by premixer
With the dual mixing of blender, mixed effect is enhanced；2nd, lighted a fire after blender, the fuel mixed is in laying refractory material
Indoor heat-accumulation combustion is fired in the expansion of flaring, has not only ensured that flameholding, abundant but also reduction oxygen demand realized low nitrogen burning；3rd, linear pattern or
Chevron-shaped expands combustion chamber wall face and training wall, prevents from being tempered, and is adapted to large space application environment, suitable for middle low-temperature burning.

Embodiment
Concrete structure of the present utility model, operation method and implementation are carried out with embodiment below in conjunction with the accompanying drawings detailed
Discuss.
The orientation such as upper, lower, left, right, front and rear in present specification term be based on position relationship shown in the drawings and
Establish.Accompanying drawing is different, then corresponding position relationship is also possible to change therewith, therefore can not be interpreted as with this to protecting model
The restriction enclosed.
As shown in figure 1, a kind of low boiling fuel burner described in the utility model, including fuel spray into 1, air compartment of pipe
2nd, premixer 3, blender 4, expansion combustion room 5, secondary air chamber 6 and igniter 8.
Fuel sprays into pipe 1 and stretches into the postmedian of premixer 3 from the front end of premixer 3, and steam state low boiling fuel sprays into from fuel
Pipe 1 sprays into premixer 3.Fuel sprays into the end of pipe 1 to be open, for anti-backflow, sprays into the end of pipe 1 in fuel and sets non-return body
