Abstract
A gas burner has a perforated, hollow body around and defining a combustion chamber. Gaseous fuel is fed to one side of the body, combustion occurs on the other side and the perforations provide a spatial connection between the fuel feed side and the combustion side. The new burner reduces exhaust gas emissions and offers a wide range of performance in the amount of heat energy provided, in the permissible range of gas pressure and in the range of fuels and fuel/air mixtures that can be used with it.
Claims3
A gas burner comprising:
- an imperforate prechamber having a top exhaust opening;
- a gas supply line coupled to the prechamber;
- a separate body inserted into and supported by the prechamber in such a manner so as to allow the body to be removed and replaced from the prechamber, the body and the prechamber defining a gas feed region therebetween;
- and wherein:
- the body is hollow with a burner region therewithin and includes a top portion that is substantially completely open and a top vent opening with a vent flange therearound;
- the prechamber exhaust opening has a fastening flange coupled to the vent flange for supporting the body in the prechamber;
- and
- the body includes perforations connecting the gas feed region and the burner region, therereby allowing combustion to take place within the burner region.
A gas flame burner including a burn-off device to which gas is supplied, the burn-off device including a shaped body formed using reticulated, high temperature resistant fibers and having a combustion gas side and a burner side, substantially the entirety of the body having perforations between the fibers providing a spatial connection between the combustion gas side and the burner side, and wherein the body is hollow and extends around the combustion chamber.
