APPARATUS OF LIQUID-FUEL COMBUSTION

摘要

PURPOSE:To prevent a high frequency noise at a combustion cylinder from being generated by a method wherein a partition plate forming a spacing of closed structure is arranged within the combustion cylinder while being opposed against a burner head and then the closed spacing is communicated with an inside part of a combustion chamber through a plurality of small holes. CONSTITUTION:A partition plate 28 is fixed to an inner surface of a rear part 20b of a cylinder and its height is located at a height opposing against a burner head. The partition plate 28 is provided with a plurality of small holes 28a and further it has ear pieces 28b bent substantially in a horizontal direction at its upper and lower portions. A longitudinal recessed hole 20e arranged at a rear part 20b of the cylinder near a connecting part 20d is located at a position displaced by about 90 deg. in respect to a center of the combustion cylinder 20 against the partition plate 28. During combustion, a primary flame formed within the combustion cylinder 20 is vibrated and a pressure variation may occur within the combustion cylinder 20 due to this vibration, although the pressure variation is accommodated under a presence of the closed spacing formed by the partition plate 28 and the recessed hole 20e. Thus, occurrence of noise of high frequency caused by the pressure variation is prevented.
