Be provided with to the pit that sinks at the center of described pallet, the pit support is on the air guide cell wall.
The angle of described infrared heating pipe and pallet is the 45-90 degree.
Described infrared heating pipe is that heat-resisting thousand laminates of siderochrome aluminium are made.
Described thermal insulation board is three layers, and the intermediate layer is a thermal insulation layer, and two outside layers is a stainless steel.
The utility model advantage compared with prior art is, air and combustion gas can well be mixed, the air pressure that mixes each position in the air cavity is even, mixed gas sprays uniformly by the wall of the equal tracheae of annular again, and the ignition temperature at each position on the infrared heating pipe is even, the raising 60% that thermal efficiency ratio is traditional, combustion flame is stable, the temperature of burning furnace chamber can reach the 950-1050 degree, and gas consumption is little, energy-conservationly reaches 30%; Because thermal insulation board is arranged, tempering phenomenon can not appear, and safe in utilization, reliable, further improved efficiency of combustion.Because the infrared heating pipe vertically is provided with, and can reduce the pollution of oil smoke to it, has improved service life.
