Example Embodiment

[0016] The regenerative flat flame burner of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 , figure 2 , image 3 As shown, a regenerative flat flame burner includes an L-shaped burner body 1 with a flue gas / air passage 2 in the burner body 1, and the channel 2 coincides with the axis of the burner body 1. The channel 2 is provided with a heat storage body 3, the burner body 1 is provided with a fuel pipe 4 and a flared burner brick 6 connected to the outlet end of the fuel pipe 4, and a cyclone 7 is provided in the channel 2 , The cyclone 7 is located in the outlet end of the channel 2, specifically the cyclone 7 is located at the end of the flue gas or air pipe 2 during fire spraying, the cyclone 7 and the channel 2 are detachably connected, so The inlet direction of the swirler 7 is perpendicular to the axial direction of the swirler 7 and is tangent to the inner wall of the swirler 7. The swirler 7 is ...

Abstract

The invention provides a heat storage type flat flame burner. The heat storage type flat flame burner comprises an L-shaped burner body, wherein a smoke or air passage is arranged in the burner body. A heat storage body is arranged in the passage, and a fuel channel and a burner brick which is of a horn mouth shape are arranged on the burner body, wherein the burner brick is connected with the outlet end of the fuel channel. A swirler is arranged in the smoke or air passage, located in the outlet end of the passage, and is detachably connected with the smoke or air passage. The heat storage type flat flame burner has the advantages that a heat storage type burning technology and a flat flame burning technology are combined, uniformity of the furnace temperature is good, energy is saved, consumption is reduced, the discharge amount of NOX can be greatly reduced, and environmental protection is benefited; components inside the burner are made of fireproof materials, so that the burner is not prone to being burnt, and the service life of the burner is prolonged; rotational flow is formed by the swirler, flames can be spread out along a plane of a furnace wall, flat flame burning is achieved, so that the flames can not be sprayed at workpieces in a hearth, and the defects that the flames are directly sprayed to the workpieces to cause local high temperature and overburning, and performance indexes of workpieces are reduced are overcome.

Description

technical field [0001] The invention relates to an industrial furnace accessory, in particular to a regenerative flat flame burner. Background technique [0002] Regenerative combustion technology is widely used in thermal processing places due to its remarkable energy-saving effect. The principle is: burners with heat storage devices are used in pairs, and when one burner burns, the other burner stores heat and exhausts smoke , The two burners burn alternately and exhaust smoke. The heat accumulator located in the burner stores heat energy when exhausting smoke. [0003] The regenerative flat-flame burner in the prior art uses the air or flue gas pipes with gradually reduced cross-sections located in the tangential direction of the inner cavity of the burner body to realize tangential air intake. This type of burner has a simple structure and uses air or flue gas The position of the flue gas pipe completes the tangential air intake, and there are disadvantages that the thi...
