Abstract

A silencer device for an industrial burner is adapted to be positioned over the air intake orifice of the burner tube of the industrial burner and provides two separate air intake paths. 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.
