Abstract
A combustion system, such as a recuperator in a furnace, has a combustion chamber, a burner which communicates with the combustion chamber and tends in operation to produce acoustic waves leading to the development of vibrations, and a conduit communicating with the burner and supplying thereto a stream of fuel fluid. The development of the waves and vibrations is precluded by providing in the conduit upstream of the burner a compartment having a volume equal to forty times the product of the cross-sectional area and the diameter of the conduit so that the acoustical waves originating in the burner are reflected, and the conduit is further intermediate the burner and the compartment so constructed as to be of unobstructed cross-section and has a length equal to substantially one-quarter of the wave length of sound waves which would develop if the vibrations were allowed to occur.
