An improved vaporized liquid fuel combustion apparatus of the type including a cylindrical combustion chamber, a blower and a heat exchanger is disclosed. An end plate located at the upstream end of the combustion chamber is formed with an air flow guide port through which combustion air is introduced into the combustion chamber. The air flow guide port is located at a position eccentric relative to the axis of the cylindrical combustion chamber. An air guide is disposed in the area located in the proximity of the air flow guide port in such a manner to generate swirl flow in the combustion chamber. The air guide may be disposed on the wall surface of the end plate either on the side located opposite to the blower casing or on the side located opposite to the combustion chamber. The air guide is preferably formed integral with the end plate by press working. To generate swirl flow a swirl flow generating air passage in the form of a circular groove may be formed in the blower casing so that air from the blower is brought to the air flow guide port in the swirled state. The swirl flow generating passage is so designed that its depth as measured from the bottom gradually decreases toward the air flow guide port on the end plate.

Liquid fuel combustion apparatus

An improved vaporized liquid fuel combustion apparatus of the type including a cylindrical combustion chamber, a blower, and end plate located between the combustion chamber and the blower and a heat exchanger for heating air by utilizing thermal energy generated in the combustion chamber is disclosed. The combustion chamber, the blower, the end plate and the heat exchanger are separable components and the blower and the heat exchanger are firmly assembled together by tightening bolts at a single flange connection with the end of the combustion chamber making gastight contact with the peripheral end part of the end plate. The one end part of the combustion chamber, the peripheral end part of the end plate are formed and the one end part of the heat exchanger are formed to mate together. Both the one end part of the combustion chamber and the peripheral end part of the end plate are formed with a plurality of holes through which bolts are inserted and the one end part of the heat exchanger is formed with a plurality of female thread holes into which the bolts are threadably engaged.
