Peterson, R J

American Can Co. has developed a new industrial-burner silencer device that avoids the loud noises commonly occurring in industrial burners when the wind direction is more or less across the wind screen of the burner's air-intake orifice. The silencer, adapted to be positioned over the air-intake orifice of the burner tube, provides two separate air intake paths so arranged that any wind that raises the air pressure at one of the entries into the air paths will lower the air pressure at the entry into the opposite air path. Wind blowing across the silencer creates a high-pressure zone at one of its ends and a balancing low-pressure zone at its other end. One of the air paths is through a central outer port and then between a cylindrical noise-suppressing core member (having a perforated conical face on one end backed by a noise-absorbent material) and the inner perforated wall of a toroid-shaped member. The other air path is through circumferential openings at the rear end of the silencer device. The silencer may be added to existing industrial burners (such as burners used to vaporize propane for fuel in drying ovens) without extensive rebuilding.
