PURPOSE:To make it possible to suppress the rise-up of flame and to safely use the titled burner by providing a flame adjusting cylinder which completely blocks the upper end of the combustion cylinder and is provided on the peripheral side surface with a plurality of through holes, at the upper part of the outer cylinder. CONSTITUTION:The upper end surface 12 of the flame adjusting cylinder 11 is completely blocked, and a plurality of through holes 14 are formed on the peripheral side surface 13. Hence, a fuel evaporated from a wick evaporating part 10a, is burnt in the combustion chamber 5 and converted into exhaust gas. The fuel rises up by a drafting but comes into collision with the upper end surface 12, and then is extended in the lateral direction. Accordingly, in a case where, for example, the quantity of combustion is abruptly changed from the lower position to the higher position, the quantity of evaporating the fuel from a wick evaporating part 10a, abruptly increases. However, since the draft dispersed in the lateral direction as indicated by arrows by the flame adjusting cylinder 11. Hence, rising flame is merely observed slightly in the lateral direction. Any large rising flame is never observed in the directly above direction of the combustion cylinder 1, and therefore, the operator harbors almost no feeling for danger. |
