Abstract

The combination oil and gas burner is designed for suppressing the noise accompanying the entrance of the air for combustion and the combustion noise. Noise of low frequency inside the furnace produced by combustion upon attempting to exit through the muffle block (14) has no direct path for outward transmission but impinges on the exposed surface of the lining (60) in the housing (20) which has an absorbing effect. Any noise striking the burner block (36) is reflected to the lining. The outward path of noise, due to the arrangement of the passageways (78, 77 and 76) with their lining (60) is such that multiple reflection by the impact of the sound waves on the walls (60, 71, 72, 73) and the exposed surfaces of the burner block (36) the tubular frame (32) and outer frame plate (22) and the closure plate (23) occurs with attenuation in the linings.
