Problems solved by technology

This form of reflashing method is not easy to maintain high temperature to ignite the fuel again, and if the torch is turned over, horizontal, inverted, dropped, etc., the reflashing effect is not good
There are also some torches equipped with a re-ignition igniter to achieve the purpose of re-igniting the torch, but the structure of the torch is complicated and the ignition effect is not good

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with specific examples and accompanying drawings.

[0029] The invention as figure 1 As shown, a torch combustion system is provided, including a burner and a fuel supply system.

[0030] fuel supply system such as image 3 , 4 As shown, it includes a fuel bottle 1 and a gas phase pressure stabilizing device 3. The bottle valve 2 is fixed at the mouth of the fuel bottle 1. The gas phase voltage stabilizing device 3 is connected to the bottle valve 2. When the burner is just working, open the gas phase voltage stabilizing device 3 and the bottle. Valve 2, the high-pressure gas-phase fuel vapor (such as propane, etc.) in the bottle is decompressed in the gas-phase pressure stabilizing device 3 through the bottle valve 2 and maintained near a relatively stable pressure value, and then enters the heating and regenerating pipe 10 . For the specific design of the fuel supply system, reference may be mad...

Abstract

The torch combustion system comprises a combustor and a fuel supply system, and the combustor comprises a main combustion chamber, a pre-combustion chamber, a re-combustion structure, a heating and heat regeneration pipeline, a main fuel pipeline, a pre-fuel pipeline and a fuel distributor. According to the invention, a reburning structure with dual functions of catalytic combustion and heat storage and reburning assistance is adopted, on one hand, the reburning structure accumulates heat and performs flameless combustion on the passing mixed gas to improve the reliability of reburning, and on the other hand, the mixed gas is subjected to catalytic combustion to improve the combustion efficiency and cleanliness, reduce the emission of pollutants such as soot and partially eliminate the problem of carbon deposition.

Description

technical field [0001] The invention relates to a torch combustion system and a combustion method thereof, belonging to the technical field of hand-held torches. Background technique [0002] In various large-scale sports games and celebrations, it is often necessary to use a hand-held torch to transfer the fire. Since the process of passing the fire is carried out outdoors, the external environment has a great influence on the combustion of the torch. At present, domestic torches generally use gaseous fuel (such as propane, etc.), the propane liquid is vaporized in the gas cylinder, and the gaseous propane vapor is supplied to the torch burner. During the gas supply process, the pressure in the gas cylinder will change greatly. If the gas is unstable, the torch cannot burn stably. Coupled with the effects of weather such as wind, rain, temperature, etc., it is very easy to cause the torch to extinguish and cannot be re-ignited. [0003] ZL200710087037.2 provides a gas flam...
