The Gas Stove Design And Implementation Of A New Type Of Combustion System

At present, the gas stove’s combustion system using three types of combustion:1)The diffusion combustion: gas nozzle to ignite combustion, if the gas does not containoxidants, oxygen needed for combustion will rely on diffusion fromthe surroundingatmosphere, the combustion that diffusion combustion, but its combustion is easy toproduce soot, the combustion temperature is quite low.2) Atmospheric burners:Pre-mixed part of the combustion air needed for enhanced combustion, increase theflame temperature, ie, partially premixed combustion. Combustion reliable and stable.3) Complete pre-mixed combustion: developed on the basis of atmospheric burners,gas and air before ignition pre-mixed chemical equivalent, set up a dedicated flue, thecombustion zone to maintain a stable high temperature to form a completely pre-mixedcombustion, but the flame is less stable.In view of the principle and characteristics of the above combustion, thecombustion system using atmospheric burners, combined with atmospheric burnersdesigned segmented and individually adjustable air combustion system, the entiredesign of the combustion system is divided into three parts:ejector design, body designand combustion head design.1)Ejector design: three-channel design to meet the gasmixture and pressure of the combustion head;2)Body design: combined ejector threeexport body, one normally open outlet lit a small fire head, the other two outletcorresponds to the dual channel segmentation of the outer ring of the head, and twooutlet can be individually controlled air intake in order to achieve low load combustionair supply to ensure that the combustion flame height constant.3)Combustion headdesign: the outer ring the head split to two separate supply channels, gas supply, thecenter the head of a separate channel from the center and outer supply, in order toachieve staged combustion.
