Low emission High efficiency domestic rich-lean combustion gas burner using knitted metal fiber mat

摘要

The present invention is a porous metal fiber to be woven on the domestic low pollution, high efficiency rich-lean combustion gas burner with a porous plate of the organization, and its object is obtained from the bunsen type combustion (bunsen Combustion) and premixed lean burn (Premixed Lean Combustion) each of the advantages in all, i.e. the gas burner of the traditional Bunsen method is pollution resistance and thermal efficiency that is excellent in flame stability of the burner, while dripping addition, before the primary air supply system of the premixed lean-burn gas burner (Premixed lean that combustion Gas burner) is pollutants sikimeuroseo employed by mixing method rich-lean combustion (Rich-lean combustion) for each selected to burn and is excellent in high seas the stability of the flame when the air range for combustion less tteoleojina resistance and heat efficiency point ( NOx and CO, etc.), domestic low pollution with a porous plate reduction and a porous metal fiber woven tissue that can talk to the flame stability of the gas burner Rich, high efficiency, to provide a lean combustion gas burner.; The present invention relates to a household gas burner appointed combustor of the gas boiler; The burner has a plurality of Bunsen type rich combustion seurit and stainless steel metal fiber woven tissues which are respectively installed gyeokbeon the burner support such that the gas flows injected by the gas nozzle and the gas nozzle for injecting the fuel introduced through the fuel supply port of the premixed lean burn to use a porous plate to the combustion surface material seurit and the rich combustion seurit the premix lean burn one side to the gas fuel inlet of seurit is provided such that on one side of the burner support contact area to the gas fuel inlet position to be installed at the lower end a burner support from each gas nozzle gas fuel and the primary air is to be positioned such that in the shielding plate and the Bunsen type rich combustion seurit and premixed lean burn seurit bottom formed hole inlet, formed with a plurality of gonggigu gas fuel inlet of the air comprising: a board-level, the premixed lean burn and its seurit To form a hole in the shielding plate which contacts the circle having the same diameter By such that air is easily introduced into the seurit when gas flows, low-emission properties and thermal efficiency is increased the stability of the fine premix lean burn the flame greatly reducing the pollutant emissions, and at the same time the domestic low pollution, high efficiency, lean-rich combustion gas by using a burner a combustible excellent porous plate to provide.
