A gas mixture combustion system

Abstract

The invention relates to a mixed gas combustion system, and relates to the technical field of combustion equipment. The mixed gas combustion system comprises a combustor, wherein a gas inlet and a gasoutlet are respectively formed in both ends of the combustor, the combustor further comprises an igniter which is arranged between a flame holder and the gas outlet, the igniter comprises a heating wire, an ignition switch and a sealing pipe, the heating wire is arranged in the sealing pipe, the ignition switch is located outside the sealing pipe and is connected with the heating wire, the lengthdirection of the heating wire is perpendicular to the axial direction of the sealing pipe, a high-temperature resistant pipe sleeves the heating wire, and a plurality of air holes which are used forairflow to pass through are formed in the surface of the high-temperature resistant pipe. The mixed gas combustion system has the beneficial effects that the manufacturing cost of the whole combustionsystem is low, the daily use and late maintenance cost is reduced, the igniter adopts the mode that the multihole high-temperature resistant pipe sleeves the heating wire, so that the heating wire isprevented from being quickly cooled in a mixed gas flow field, and the ignition energy can be adjusted in multiple positions, so that mixed gas is efficiently ignited by the igniter, and the efficiency of the combustion system is improved.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a mixed gas combustion system. Background technique [0002] When studying the combustion characteristics of fuel, a visual combustion system is needed to study the ignition characteristics of fuel and the stable combustion process of the flame. The combustion system requires that the combustible mixture can be ignited reliably at different flow rates. How to achieve reliable ignition and stable flame combustion of the combustible mixture at high flow rates in the combustion system is a key technical problem that needs to be solved. At present, the combustion system has the defect that the ignition element dissipates heat too quickly when the mixture flow rate is high. When the high flow rate mixture flows through the ignition element, the ignition element dissipates heat too quickly, resulting in insufficient ignition energy; When it is high, it is difficult for el...

AI Technical Summary

Problems solved by technology

At present, the combustion system has the defect that the ignition element dissipates heat too quickly when the mixture flow rate is high. When the high flow rate mixture flows through the ignition element, the ignition element dissipates heat too quickly, resulting in insufficient ignition energy; When it is high, it is difficult for electric spark ignition to form a fire nucleus or the fire nucleus is easy to quench, and there are often problems such as insufficient ignition energy and unreliable ignition.
