Abstract

PURPOSE:To improve characteristic of exhaust gas by providing a burning control cylinder for forming an air chamber in the inside of an air hole of an outer flame cylinder and making the air holes of the lower part of a burning control cylinder enlarge opening ratio more than those of the wick neighborhood in regard to combustion equipment such as a petroleum stove for a household. CONSTITUTION:A burning control cylinder 29 for forming an air chamber 31 is provided in the inside of air holes 34 of an outer flame cylinder 7 of the combustion equipment. The air holes 34 of the lower part of the burning control cylinder 29 has larger opening ratio than the wick neighborhood of the air holes 33 with providing a communicating hole 32 on the wall of the burning control cylinder 29. Therefore, unburnt gas is locally burned in an air chamber 31 by the air from the air holes 30 of an outer flame cylinder 7, leakage of the unburnt gas is lessened to the outside of the outer flame cylinder 7, the flow of air is produced along the outer flame cylinder 7, while leaked unburnt gas is drawn by the draft of the furnace 8 in a furnace 8 to burn and deterioration of exhaust gas characteristic is prevented. At this time the unburnt gas in the furnace 8 flowed from an inner flame cylinder 6 and the characteristic of exhaust gas can be made good because the opening ratio of the air holes 34 is large.
