“双前拱”燃烧技术在层燃链条锅炉上的应用

Application of the″Doulile-front arch″BurningTechnology in the Chain-stoner Furnace of deek-burn-ing

“双动拱”是一种新型的锅炉炉拱，它使煤得到更充分的燃烧、火焰温度提高约２００℃，锅炉效率提高１０％以上，节煤效果显著。采用该炉拱后，锅炉还可以正常燃用劣质烟煤，甚至无烟煤，有利于开发利用煤炭资源。

ouble-front Arch″is a new boiler’s arch,with which coal burns more completely,the temperature offire goes up about 200℃‘and the boiler efficiency rises by10% and above,It is very effective to economice on coal. with the new boiler’s arch,bituminous coal of poor quali-ty,even anthracite,can also burn normally,It helos tomake full use of the coal resources.
