Abstract: The invention relates to a burner with surface burning, which comprises a burner head (12) having a housing (14), which has a supply (18) for a fuel-air mixture upstream and has a fabric membrane (16) downstream on an outlet side and comprises a flame flash-back barrier (17), which is arranged upstream of the fabric membrane (16) at a distance to this, wherein at least the fabric membrane (16) and the flame flash-back barrier (17) are arranged by at least one releasable connection element (54) which engages with a receiving region (47) in the housing (14).

Abstract: A combustion method of a mixture composed of air and fuel uses a precious metal fiber membrane (1), wherein additional openings (3) for generation of a flame field with higher flames (8) are provided, the roots (7) of which are kept cool for NOx reduction, among other things.

Abstract: The invention relates to a production method for a burner fabric membrane (1) consisting of special steel fabric layers for burning fuel/air mixtures. Additional passages (4) in the fabric (8) are produced by the displacement of the fabric and the mouths of the passages protrude from the membrane surface (3).

Abstract: A burner head for a forced-air gas burner having a combustible gas distributor and a combustion air distributor, having radially disposed combustible gas nozzles and axially extending combustion air flow openings, in which the flame root is formed in the vicinity of the nozzles and flow openings, with ribs protruding radially into the flame region downstream of the flame root. A flame tube is provided coaxially with the burner tube, and an annular gap is provided for exhaust gas recirculation between the burner tube and the flame tube.

Abstract: A furnace system is provided with exhaust gas recirculation via a recirculation tube having an inlet mounted downstream of the furnace firing area and an inlet disposed in juxtaposition to the blower fan wheel of the furnace blower. The recirculated gases can enter the tube from either the stack or the firebox. The inlet penetrates the air intake plenum either axially thereof or at an angle thereto through a sidewall. The furnace includes both an air intake throttle and an air intake butterfly control valve. An exhaust gas recirculation control valve can be linked to the air intake control butterfly valve for their operation in concert. The air intake throttle is either a rigid baffle or a pivotable flap.
