JPS6057111A - Evaporating device of evaporating type kerosene burner - Google Patents

Abstract

PURPOSE:To prevent production of a tar content, by a method wherein a medium having an evaporating temperature lower than that of kerosene is fed in an evaporating chamber. CONSTITUTION:By feeding water into a heater 2 in a similar way to feed kerosene in a preheated evaporating chamber 1, water is evaporated to generated a large amount of steam in the evaporating chamber 1. The generated steam causes shortening of an evaporating time of kerosene and prevents production of tar. Prevention of production of tar in the evaporating chamber permits maintenance of stable combustion performance for a long period of time.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a vaporizing oil combustor, and particularly to a vaporizing device thereof.

<Conventional technology> FIG. 1 shows the main parts of this type of device.

In the figure, reference numeral 1 denotes a vaporization chamber with a heater 2 fixed to its outer surface, an oil supply pipe 3 connected to the bottom, and a nozzle part 4 at the top.
is formed. Reference numeral 5 denotes a burner section in which vaporized petroleum gas ejected from the nozzle section 4 is burned.

That is, in this type of combustor, oil is pumped by a pump (not shown) into the vaporization chamber 1 through the oil pipe 3.
; sent. This petroleum is heated and vaporized in the vaporization chamber 1 by the heater 2, and is ejected from the nozzle portion 4 as vaporized gas. This vaporized gas is combusted in the burner section 5 as described above.

However, in the process of heating and vaporizing oil in vaporization chamber 1,
As petroleum decomposes and polymerizes to generate tar, tar gradually adheres to the inner wall of the vaporization chamber 1. This tar impairs heat conduction from the heater 2 and prevents the vaporization of petroleum. If the amount increases, there is a problem that sufficient vaporized gas will not be generated from the vaporizing chamber 1, making it impossible to continue combustion.

<Purpose> The present invention was made to eliminate the above-mentioned drawbacks, and it suppresses the generation of tar by feeding not only oil into the vaporization chamber but also a medium whose vaporization temperature is lower than that of oil. The present invention provides a vaporizing device that provides a.

<Embodiment> FIG. 2 shows the main parts of the apparatus of the present invention, and the same parts as in the conventional example are denoted by the same reference numerals. In the figure, 6 is a water pipe connected to the vaporization chamber 1, and 7 is a water pump.

When water is sent into the vaporization chamber 1 which has been preheated by the heater 2 in the same way as oil is sent, the water is vaporized and a larger amount of water vapor is generated in the vaporization chamber 1 than in the past. The presence of this water vapor reduces the vaporization time of the oil and prevents the formation of tar.

If the oil vaporization time is short, tar generation is suppressed.

Note that alcohols or hydrocarbons can be used instead of water. The key is the vaporization temperature of oil (150°C to 250°C)
) Any medium with a lower vaporization temperature may be used.

Other examples It is designed to be sent into the conversion chamber 1.

Further, in FIG. 1, water may be mixed with petroleum and the mixture may be fed into the vaporization chamber 1.

<Effects> According to the vaporization device of the present invention, the generation of tar in the vaporization chamber is suppressed, so it is possible to provide a vaporization oil combustor that maintains stable combustion performance over a long period of time. .
