Abstract
A burner for an industrial furnace has a plurality of lines passing through a furnace wall for fuel gas, burner air, and waste gas. Arranged in the furnace space is a combustion chamber (66) in which a mixture of fuel gas and burner air is combusted, and from which a flame (89) is directed into the furnace space. The combustion chamber (66) is delimited by walls (32, 65). The walls (32, 65) are arranged to be movable with respect to one another (65', 65"), so that the volume of the combustion chamber (66) is adjustable (FIG. 2).

A burner for an industrial furnace, comprising:
- a first burner portion located outside the furnace and having first connector means for feeding a fuel, second connector means for feeding air, and third connector means for electrical energy;
- an ignition electrode within said second electrode portion and electrically connected to said third connector means;
- a first cylindrical tube extending from said first burner portion to a free end located within the furnace, said free end being tapered radially inward toward the furnace, said first cylindrical tube being operatively connected to said second connector means;
- a second cylindrical tube extending within said first cylindrical tube from said first burner portion to a free end, said second cylindrical tube being operatively connected to said first connector means;
- and
- a radial plate mounted adjacent said free end of said second cylindrical tube and within said first cylindrical tube, and having at least one opening to allow the air within said first radial tube to pass thereby, said radial plate and the portion of said first cylindrical tube between its free end and the radial plate defining a combustion chamber, with said electrode mounted upon said plate and within said combustion chamber.
