Liquid extraction type torch combustion system and method

Abstract

The liquid extraction type torch combustion system comprises a combustor and a fuel supply system, the fuel supply system comprises a fuel bottle and a liquid extraction device, and the combustor comprises a main combustion chamber, a premixing chamber, a recombustion structure, a heating pipeline, a main fuel pipeline, a premixing chamber inlet fuel nozzle, a premixing chamber outlet gas mixing nozzle 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 carries out flameless combustion on the passing mixed gas to further 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 and reduce the emission of pollutants such as soot, so that the energy-saving and environment-friendly effects are achieved. And the problem of carbon deposition is partially eliminated.

Description

technical field [0001] The invention relates to a liquid-lifting torch combustion system and method, and belongs 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. Especially at low temperature, the gaseous fuel m...

AI Technical Summary

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
