Abstract

A találmány tárgya eljárás és elrendezés gázok tűztérben valóelégetésére, főként alacsony fűtőértékű gázok elégetésére egyalapvetően másféle fő tüzelőanyaggal üzemeltetett kazánban. Atalálmány lényege az, hogy egy gázfejlesztőben (5) előállítotttermékgázt vagy egyéb éghető gázt a tűztér (2) alsó részében (10)levegőhiányos feltételek közé vezetünk be, majd a gázt feljebb égetjükel a tűztérben (2), az égéslevegő-bevezetés kívánt szintjén vagy többégéslevegő-betáplálási szinten. ÓThe subject of the invention is a method and arrangement for burning gases in a firebox, mainly for burning gases with a low calorific value in a boiler operated with a fundamentally different type of main fuel. The essence of the invention is that product gas produced in a gas generator (5) or other combustible gas is introduced into the air-deficient conditions (10) in the lower part of the fire chamber (2), and then the gas is burned higher up in the fire chamber (2), at the desired level of the combustion air introduction or multi-combustion air -feed level.
