FLUEGAS SLIT CAVITY MUFFLER

摘要

A muffler for a heat engine such as burner and a heating system are described. The muffler comprises an inlet (100), an outlet (105) and a tube assembly (110) arranged between the inlet and the outlet. The tube assembly comprises an inner tube (112) having an inlet opening (112.1) in fluid communication with the inlet (100) and an outlet opening (112.2) in fluid communication with the outlet (105). The tube assembly (110) further comprises an outer tube (114), at least partly surrounding the inner tube (112), thereby defining a cavity (120) between the inner tube (112) and the outer tube (114), whereby a side of the cavity (120) arranged at an outlet side of the muffler is closed and whereby a side of the cavity (120) arranged at an inlet side of the muffler is provided with an opening, wherein said opening is slit-shaped (130). The muffler may advantageously be in a heating system including a heat engine, preferably in an upright position such that the inlet opening is arranged lower than the outlet opening.
