Sleeve type gas combustor with electronic ignition device

Abstract

The invention discloses a sleeve type gas combustor with an electronic ignition device. The sleeve type gas combustor comprises a combustion chamber, a gas input pipe and the electronic ignition device. The combustion chamber comprises an inner barrel and an outer barrel, the bottom of the inner barrel is communicated with the gas input pipe, the outer barrel is coaxially installed on the outer portion of the inner barrel and wraps the inner barrel, a combustion transition cavity is formed between the outer barrel and the inner barrel, the inner barrel is made of a high temperature resistant metal material, a barrel body is provided with a plurality of evenly densely distributed gas escape holes, and a barrel body of the outer barrel is of a multilayer structure. The sleeve type gas combustor is compact in structure, good in tempering resistance effect, convenient to use and install, low in fabricating cost and good in popularization and application value.

Description

technical field [0001] The invention relates to the field of coal mine safety, in particular to a gas burner for safely burning low-concentration coal mine gas. Background technique [0002] Coal mine gas, also known as coalbed methane, refers to the self-storage natural combustible gas in the source rock of occurrence and gas generation. Its main component is methane, which is a high-quality energy source and can be used as fuel and chemical raw materials. Coal mine gas is also a strong greenhouse gas. The GWP value (global warming potential) is equivalent to 21 times that of carbon dioxide. The total gas emission in my country is about 7.7 billion cubic meters per year, most of which are directly discharged into the atmosphere. , causing serious harm to the environment. In addition, coal mine gas is a flammable and explosive gas. When it is mixed with air or oxygen to reach a certain concentration, it can burn or explode under the action of a certain induced energy, which ...

AI Technical Summary

Problems solved by technology

In addition, coal mine gas is a flammable and explosive gas. When it is mixed with air or oxygen to reach a certain concentration, it can burn or explode under the action of a certain induced energy, which brings safety hazards to coal mining. At present, many The gas extracted from most mines is transported by pipeline, and the output end of the pipeline is connected to the user. Since most of the extracted gas concentration is lower than 30%, the gas in the pipeline is easy to burn and explode in case of fire, that is, there is a certain potential safety hazard.
