Description

[Detailed explanation of the invention] The second invention relates to a liquid fuel combustion device in which combustion air and fuel are mixed and injected into the vaporization cylinder. The heat shield plate and the heat insulating material are polymerized and fixed to prevent the temperature of the burner head from rising during combustion.

This invention will be explained below based on an illustrated example. Reference numeral 1 denotes a blower, and air is supplied to an air supply pipe 2.

Reference numeral 3 indicates an oil level regulator that maintains a certain oil level at all times, 6 indicates a static pressure return pipe that communicates the air supply pipe 2 with the air chamber 4 of the oil level regulator 3, and 5 indicates a supply of fuel from the oil level regulator 3. The tip of the fuel supply pipe is placed a small distance X above the oil level of the oil level regulator 3.

7 is a part of the burner, which includes a burner head 8 and a vaporizer cylinder 9.
, a heater 10, and a partition plate 11.

The air supply pipe 2 is attached to the body of the vaporization tube 9, and 12 vaporization chambers are formed inside the vaporization tube 9.
The upper part of the burner head 8 is partitioned by a partition plate 11 having a hole in the center, and above the burner head 8, a circular heat shield plate 14 made of stainless steel or the like holds down a circular heat insulating material 13 such as asbestos, and prevents screws or rivets. 15 etc. to the burner head.

To explain this embodiment having the above configuration, first, the heater 10 is energized to preheat the vaporizing tube 9, and when the vaporizing surface temperature reaches a set value or higher, the blower 1 starts blowing air into the air supply pipe 2, At the same time, the static pressure of the blown air is applied to the air chamber 4 in the oil level regulator 3 through the static pressure return pipe 6 and presses the oil level.

The pressed fuel is pushed out from the fuel supply pipe 5, is blown off by the surrounding air jet, becomes atomized, spreads in a conical shape, enters the vaporization chamber 12, collides with the inner surface of the vaporization cylinder 9, is heated and vaporized, and becomes molecular. The mixed gas is mixed with the surrounding air and collected in the holes of the partition plate 11 to make the mixed concentration uniform, and reaches the flame opening of the burner head 8, where it is ignited and burned by an appropriate ignition means.

In the conventional type, the heat shield plate 14 and the heat insulating material 13 were not provided above the burner head 13, so the burner head 8 became extremely hot due to the radiant heat of the flame, causing thermal deformation and embrittlement. , flashbacks and longevity were issues.

However, according to this invention, since the heat shield plate 14 and the heat insulating material 13 are superimposed and fixed on the burner head 8, the burner head 8 is protected from the heat of the flame and does not become abnormally high temperature. Therefore, a safe combustion device can be obtained by preventing thermal deformation and embrittlement.
