Burner for Stirling engines

摘要

A burner for a Stirling engine includes a baffle for partitioning the interior of a housing into an air chamber and a combustion chamber, the baffle having a centrally located cylindrical portion of tapered configuration, and a generally cylindrical ceramic burner cone for primary combustion of an air-fuel mixture, the burner cone being inserted into and retained by the cylindrical portion of the baffle and having a tapered outer circumferential surface and an annular end face on an upstream side thereof. The baffle is equipped with an engagement portion having an annular outer circumferential surface for engaging the annular end face of the burner cone. The burner cone is retained by the tapered cylindrical portion of the baffle and the engagement portion. If the burner is used in the horizontal attitude, the weight of the burner cone is supported by the engagement portion and tapered cylindrical portion of the baffle, so that the burner cone can be reliably retained without tilting even if the baffle expands owing to the heat of combustion.
