Integrated whole-air-inlet combustor

Abstract

The invention discloses an integrated whole-air-inlet combustor which comprises a furnace head, a support and a base integrally formed with the support. The base is arranged in the support. The furnace head is arranged below the support. A first air inlet nozzle and a second air inlet nozzle are arranged on the furnace head. The base is provided with a first ejection pipe and a second ejection pipe. The base is provided with an outer ring groove, a middle ring groove, an inner ring groove and a through hole. The first ejection pipe communicates with the inner ring groove, and the second ejection pipe communicates with the outer ring groove. An energy accumulation plate is arranged on the support. A third air inlet is formed between the energy accumulation plate and the outer ring groove. A fourth air inlet is formed in the middle ring groove. According to the integrated whole-air-inlet combustor, due to the fact that the energy accumulation plate is arranged, carbon monoxide generated during combustion is separated from air needed in combustion, and the combustion efficiency is improved; and in addition, the multiple air inlets are formed so that it can be ensured that fuel gas is evenly mixed with air, and combustion is sufficient. The support and the base are integrally formed, and manufacturing and assembling are convenient. In addition, the multiple air inlets are formed so that it can be ensured that fuel is evenly mixed with air, and combustion is sufficient.

Description

technical field [0001] The invention relates to the field of cookers, in particular to an integrated full-air intake burner. Background technique [0002] At present, most of the existing household gas burners are atmospheric burners, also known as partial premixed burners. Its working principle is: under a certain pressure, the gas flows out from the nozzle at a certain flow rate and enters the ejector pipe, relying on the ejection effect of the energy of the gas itself, to attract a certain amount of surrounding air, which is called "primary air". The primary air and gas are mixed in the injector tube and the mixing chamber of the burner, and then flow out through the fire hole for combustion. During the combustion process, air is drawn from around the flame to support the combustion. This part of the air is called "secondary air". [0003] However, the carbon monoxide generated during the combustion of the existing burner is not easy to discharge, and will be mixed with...

AI Technical Summary

Problems solved by technology

[0003] However, the carbon monoxide generated during the combustion of the existing burner is not easy to discharge, and will be mixed with air and gas for combustion in the injector tube and the mixing chamber of the burner, resulting in a decrease in the oxygen content in the air, uneven mixing of the gas and oxygen, and low combustion efficiency.

In addition, fewer air inlets of the burner will lead to insufficient secondary air, resulting in an unsatisfactory mixing ratio of air and gas, resulting in combustion defects such as yellow flames, which greatly reduces combustion efficiency
