Embodiment 1

[0033] figure 1 It shows a schematic view of the internal structure of the burner 100 provided by the embodiment of the present application at a first angle of view, please refer to figure 1 , this embodiment provides a burner 100 .

[0034] The combustor 100 mainly includes an air intake chamber 110 , a combustion assembly 120 and a combustion chamber 130 . The combustion chamber 130 is used to divide the burner 100 into an intake chamber 110 and a combustion chamber 130 , in other words, along the gas intake direction, the two sides of the combustion assembly 120 are the intake chamber 110 and the combustion chamber 130 respectively. The gas enters the burner 100 through the intake chamber 110 , is ignited by the combustion assembly 120 and burns in the combustion chamber 130 .

[0035] figure 2 A schematic diagram of the internal structure of the burner 100 provided by the embodiment of the present application at a second viewing angle is shown.

[0036] see figure 1 ...

Embodiment 2

[0072] image 3 Shows a schematic structural diagram of the combustion equipment 200 provided by Embodiment 2 of the present application, please refer to figure 1 , figure 2 as well as image 3 , the present application also provides a combustion equipment 200, the combustion equipment 200 includes the gas mixing chamber 210 and the above-mentioned burner 100, please refer to the embodiment 1 for the burner 100, and the details will not be described in this embodiment. The air mixing chamber 210 communicates with the intake chamber 110 of the combustor 100 .

[0073] The gas mixing chamber 210 is mainly used for mixing gas and supporting gas. In this embodiment, the supporting gas is air, and the supporting gas is introduced by a fan. It should be noted that, in other embodiments of the present application, the supporting gas may be oxygen.

[0074] Now the mixture in the air-mixing chamber 210 is mixed and then transported to the burner 100 for combustion through the int...

Abstract

The invention relates to the field of equipment, in particular to a combustor and combustion equipment. The combustor comprises an intake chamber, a combustion chamber and a combustion assembly, wherein combustion assembly comprises a porous medium and first cooling tubes which are connected to each other, the combustion assembly is provided with at least one channel for fuel gas to pass through, and at least two side walls of each channel are the first cooling tubes. The resistance of the part entering the combustion chamber through the channel for combustion is small, the combustor can rapidly enter the combustion state, and the problem that flame detection is unstable when the load of porous medium combustion is small is solved; and meanwhile, the combustion resistance is reduced, and rapid combustion drives the porous medium to conduct flameless combustion; the combustion state of the part of flameless combustion conducted through the porous medium is stable, heat provided by the combustion part of the porous medium to the outside plays a role in stabilizing the flame of the combustion part through the channel, and the problem that the flame of the combustion part entering the combustion chamber through the channel is unstable is solved.

Description

technical field [0001] The present application relates to the field of equipment, in particular, to a burner and combustion equipment. Background technique [0002] Porous media combustion is a combustion method in which porous media is added to the burner. The burner with porous media has three heat transfer modes of convection, heat conduction and radiation, so that the temperature in the combustion area tends to be uniform and maintains a relatively stable temperature gradient. Compared with free combustion, porous media combustion has the advantages of high combustion rate, good combustion stability, large load adjustment range, large heat accumulation intensity, small burner volume, good gas adaptability, low pollutant emission in flue gas, It has the advantages of widening the combustion limit and combustible gas with low calorific value. [0003] However, the porous media burner has the problem of excessive combustion resistance at low load. Contents of the invent...
