Novel high-efficiency energy-saving environmentally-friendly combustor

Abstract

The invention belongs to the technical field of combustors and relates to a novel high-efficiency energy-saving environmentally-friendly combustor. The novel high-efficiency energy-saving environmentally-friendly combustor comprises a main body. The main body comprises an outer ring flame generator with an outer ring mixing chamber. An outer ring combustor cover is arranged above the outer ring mixing chamber. The outer ring combustor cover is provided with an outer ring fire hole. The outer ring mixing chamber is connected to an outer ring injection tube. The novel high-efficiency energy-saving environmentally-friendly combustor is characterized in that an infrared combustor is arranged in the main body; the infrared combustor comprises an inner mixing chamber connected to an inner injection tube and a combustor plate arranged above the inner mixing chamber; the combustor plate is arranged above the main body formed from the outer ring combustor cover; and the combustor plate is provided with a fire hole. The novel high-efficiency energy-saving environmentally-friendly combustor realizes combination of an atmospheric combustor adopting an open fire combustion technology and an infrared combustor adopting an infrared low fire combustion technology and improves combustor combustion efficiency and exchange efficiency.

Description

technical field [0001] The invention belongs to the technical field of burners, and in particular relates to a high-efficiency, energy-saving and environment-friendly burner. Background technique [0002] Burners have been popularized in the kitchen now. The main way of traditional burners is the outer ring fire plus the middle ring fire with a small power ratio. During the combustion process, in order to increase the effective contact with the air and fully burn, the middle ring burner The supplement of secondary air is needed for normal combustion. Any time the air is insufficient, there will be yellow flames during combustion, insufficient combustion and other phenomena, resulting in excessive carbon monoxide in the flue gas. Moreover, there is a blind zone in the heating between the two rings of fire, which greatly reduces the thermal efficiency of the burner, thereby wasting energy and time. In addition, the thermal efficiency of traditional burners is generally betwee...

Problems solved by technology

[0002] Burners have been popularized in the kitchen now. The main way of traditional burners is the outer ring fire plus the middle ring fire with a small power ratio. During the combustion process, in order to increase the effective contact with the air and fully burn, the middle ring burner The supplement of secondary air is needed for normal combustion. If there is insufficient air at any time, yellow flames will appear during combustion, and insufficient combustion will cause the carbon monoxide in the flue gas to exceed the standard.

Moreover, there is a blind area in the heating between the two rings of fire, which greatly reduces the thermal efficiency of the burner, thus wasting energy and time

In addition, the thermal efficiency of traditional burners is generally between 50 and 55%, and has not yet reached 65%.

[0003] In order to solve the shortcoming that traditional burners need secondary air, infrared burners have appeared on the market. Although the combustion does not require secondary air, the primary air is all provided by natural injection, but in order to make the gas and air mix fully and evenly, it is necessary to compare Long mixing tubes or large mixing chambers will result in a larger diameter of the combustion disk than the atmospheric burner, about Φ150mm. The actual thermal efficiency of using a small pointed bottom pan will be greatly reduced, and the heat flow of the burner will be greatly reduced. Only about 3.5kW, this kind of heat flow is not suitable for Chinese people's cooking habits of stir-frying and stir-frying, so the market share is very small
