Problems solved by technology

[0003] But the metal infrared combustion plate in the above-mentioned patent still has the following defects: 1, because the apertures of the fire holes on the boss in the patent and the fire holes on the combustion panel are the same, the holes of each fire hole The resistance is the same, and the heat and thermal lift generated by the combustion in the hole are also the same. During use, only ordinary flames are generated on the combustion panel, and after heating, infrared combustion without flames occurs on the combustion panel. The combustion is mainly carried out by heat radiation. Heating, the addition of bosses only increases the surface area of ​​the combustion plate, so the thermal efficiency still needs to be further improved; 2. In this patent, it is a whole metal plate. Because the heat conductivity of the metal plate is good, the temperature and temperature at the top of the boss are The temperature of the air-receiving surface at the bottom of the metal plate is very close, so the temperature of the combustion plate cannot be high, otherwise tempering phenomenon (that is, burning under the combustion plate) will occur, so the combustion plate of this patent can only rely on the boss structure to increase Large area, increase thermal radiation to improve thermal efficiency, and because it is a whole piece of metal, the preheating process is very slow, otherwise the preheating is too fast, the thermal balance will be broken, tempering will occur, and there will be separation during the preheating process. Structural issues such as flames
After use, the combustion plate will maintain a high temperature for a long time and cool down slowly

Embodiment 1

[0035] In this embodiment, the main improvement lies in the furnace plate, which can be applied to various existing burners. In order to better understand the furnace plate structure, it is now applied to the burner described below in detail.

[0036] like figure 1 As shown, the burner in this preferred embodiment includes a burner 2, a gas nozzle 3, a blower 6, and a stove plate A. The burner 2 is installed on the lower end surface of a kitchen stove 20, and the stove 20 is provided with a 23 for supporting a pot. The bracket 22.

[0037] A premix chamber 21 is formed inside the burner 2, the gas outlet end of the gas nozzle 3 is connected to the premix chamber 21, the blower 6 can blow air into the premix chamber 21, and the furnace plate A is arranged in the burner 2 and covered with a Above the premix chamber 21. The wind blown by blower 6 is not only used to ensure that the combustion gas is fully combusted, but also reduces the temperature of the lower surface of the fu...

Embodiment 2

[0055] like Figure 11 As shown, in this embodiment, the structure of the fourth slat 162 is different from that of Embodiment 1, and others can refer to Embodiment 1.

[0056] The fourth slat 162 includes a plurality of plates 1622 arranged in sequence along the left and right directions, and each plate 1622 is inclined toward the wall 16221 of the adjacent plate 1622 from top to bottom toward the direction close to each other, thereby forming a gap between two adjacent plates 1622. The vertical section is tapered gap 1623, that is, the second through hole 12 formed in this embodiment is a through hole with a large top and a small bottom, which can reduce the flow rate of combustion gas (mixed gas and air) and improve the stability of combustion . The longitudinal section of the above-mentioned gap 1623 is not limited to a tapered shape, for example, it can also be a stepped hole whose diameter gradually decreases from top to bottom. .

Embodiment 3

[0058] like Figure 12 , 13 Shown, in the present embodiment, the structure of stove plate A is different from embodiment 1, other can refer to embodiment 1.

[0059] In this embodiment, the panel 1 is a whole board, and the material of the panel 1 can be metal, ceramic or powder alloy, etc., because the thermal conductivity of the ceramic material and the powder alloy material is poor, so it can be made into a whole board, but the ceramic material The mechanical strength is poor, and it is easy to break, weather, peel off, etc.; as for the powder alloy material, it depends on its metal content. If the metal content is high, its properties are close to metal plates. If the metal content is low, it will exist like ceramic plates. flaws, but cheap.

[0060] The panel 1 is provided with a plurality of first sockets 14 and a plurality of second sockets 13, each of the first sockets 14 is inserted with a hollow columnar body 141, and the hollow part of the columnar body 141 forms...

Abstract

The invention relates to a furnace plate for a combustor. The furnace plate comprises a panel, a boss is arranged on the panel, the upper end surface of the boss is higher than the upper end surface of the panel, a plurality of vertically-through first through holes are formed in the panel, second through holes penetrating through the wall thickness of the panel and the boss are formed in the panel, the periphery of each second through hole is provided with the first through holes, and the furnace plate is characterized in that the area of each second through hole is larger than that of each first through hole. Through cooperation of the first through holes and the second through holes, heating is conducted through heat radiation and flame combustion, and due to formed tandem continuous combustion, the whole furnace plate is heated evenly, and the combustion efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a furnace plate used on the burner. Background technique [0002] The burner is a device that makes gas and air spray out and burn in a certain way. The furnace plate is an important part of the burner, and its performance will directly affect the thermal efficiency of the burner. For example, "A Metal Infrared Combustion Panel and a Burner with the Combustion Panel" disclosed in the Chinese utility model patent No. CN201320445519.1 (announcement No. CN 203413637U), the metal infrared combustion panel disclosed in this document is the furnace plate, the metal infrared combustion plate comprises a combustion panel, on the upper surface of the combustion panel there are several bosses, and one or more through of the fire hole. The upper surface of the metal infrared burning plate is provided with several boss structures, which increases the surface area of ​​the burning plate, th...
