Abstract

PURPOSE:To control excessive flame and prevent the production of CO odor and soot in the case where fuel adjusting width is changed suddenly by providing a plurality of projected parts from the upper part of an outer flame cylinder to the direction of an inner flame cylinder in regard to burning equipment of a petroleum stove for household use. CONSTITUTION:In the case where burning quantity is suddenly changed from large one to small one, a gasification quantity of fuel is suddenly increased, unburnt gas reaches the upper part of a furnace 8 and control of excessive flame can be performed in order that gas flow is disturbed and mixing is accelerated by a plurality of projected parts 33 provided to come into contact with unburnt gas layers which rise in the furnace 8 in the upper part of an outer flame cylinder 7 and flame is subdivided by the projected parts 33. Since the position of the projected parts 33 is upward provided from the upper end of an inner flame cylinder 6, nonconformity caused by the increase of ventilation resistance in the upper part of the furnace can be avoided. Since an air hole 13 provided in a top plate 12 of the inner flame cylinder 12 is set in the upstream side from the projected parts 33, air supplied from the air hole 13 is also effected by the projected parts 33 and mixing condition of air and unburnt gas is good.
