（産業上の利用分野）
本考案はボイラーや焼却炉等で使用されるもの
であり、多量の水分を含んだ廃油や油分を含んだ
廃液（以下廃油と呼ぶ）を燃料の一部として利用
し、一つの燃焼装置でもつて廃油を効率よく燃焼
し得るようにした燃焼装置に関する。[Detailed description of the invention] (Industrial application field) This invention is used in boilers, incinerators, etc., and is used to process waste oil containing a large amount of water or waste liquid containing oil (hereinafter referred to as waste oil). The present invention relates to a combustion device that can efficiently burn waste oil using one combustion device as part of fuel.
（従来の技術）
廃油の燃焼には、予かじめ重油等の主燃料油
と廃油とを混合し、両者の混合体をバーナへ圧送
するようにした混合燃焼方式と、主燃料油用バ
ーナと廃油用バーナとを併設し、主燃料油の助燃
によつて廃油を燃焼するようにした助燃燃焼方式
が、一般に広く利用されている。(Prior art) There are two methods for combustion of waste oil: a mixed combustion method in which main fuel oil such as heavy oil and waste oil are mixed in advance and the mixture of both is fed under pressure to a burner; An auxiliary combustion method is generally widely used in which a waste oil burner is installed and the waste oil is combusted by auxiliary combustion of the main fuel oil.
しかし、前者の混合燃焼方式にあつては、廃油

定等の様々な不都合が生じるうえ、媒塵の発生量
が極めて多いという問題がある。 However, in the case of the former mixed combustion method, if the water content of the waste oil is high, separation of oil and water is likely to occur in the piping for pumping fuel, and if separation of oil and water occurs, it may occur in the piping. Rust on walls, overheating of oil heaters,
In addition to causing various problems such as cavitation of the oil pump and unstable combustion, there is also the problem that an extremely large amount of dust is generated.

いこと、主燃料油が低質油の場合には、低出力
燃焼時のみならず、着火時や燃焼制御時に於いて
も燃焼が不安定になり易いこと、媒塵の発生量
が多くなること等の問題がある。 In addition, the latter auxiliary combustion method requires a combustion device for the main fuel and a combustion device for waste oil, which increases equipment costs and requires a lot of effort to maintain and manage the equipment. Because the main fuel and waste oil are ejected separately, if waste oil with a high moisture content is ejected during low-output combustion such as in so-called three-position combustion control, the combustion state tends to become unstable due to a drop in temperature. When the fuel oil is of low quality, there are problems such as combustion tends to become unstable not only during low-output combustion but also during ignition and combustion control, and a large amount of dust is generated. .

ものとなる。(Function) The main fuel oil A, such as heavy oil, heated and pressurized to a predetermined temperature and pressure is stored in the stem 6 even when the combustion equipment is stopped.
It circulates through the circulation passage 27. As a result, the stem 6 is always kept in a high temperature state, and the waste oil amount control orifice 4 etc. are always kept warm by heat transfer from the main fuel oil control valve, so that even if the main fuel oil A is low quality oil, ignition will not occur. In addition to being carried out smoothly, combustion becomes more stable during low-output combustion and combustion control.
廃油循環回路Ｄ及び主燃料油循環回路Ｃが所定

廃油Ｂ及びこれに含まれる水分の三者が十分に強
制混合され、エマルジヨン油が形成される。 When the waste oil circulation circuit D and the main fuel oil circulation circuit C reach a predetermined temperature and pressure, the main fuel oil control valve 3 is first opened and the main fuel oil A jetted from the nozzle 29 of the stem 6 is ignited. After that, the waste oil control valve 13 is opened, and the main fuel oil A and waste oil B mixed in the waste oil amount control orifice 4 are transferred to the stirring inner pipe 26 of the stem 6.
supplied within. Inside the inner pipe 26, the main fuel oil A, the waste oil B, and the water contained therein are sufficiently forcibly mixed to form emulsion oil.
形成されたエマルジヨンはノズル２９から噴出

環回路Ｃは不要となり且つ前記ステム６の循環通
路２７も不要となる。 On the other hand, when the main fuel oil A is high-quality oil such as kerosene, the waste oil B can be burned relatively stably even during ignition and combustion control. Therefore, the main fuel oil circulation circuit C is not necessary, and the circulation passage 27 of the stem 6 is also not required.

料がノズル２９から噴出され、燃焼される。 The waste oil B supplied through the waste oil amount control orifice 4 is mixed with the main fuel oil A and enters the stem 6, and while passing through the inner pipe 26, the main fuel oil A and waste oil B are forcibly mixed by the member 21. will be carried out. That is, in the inner pipe 26, so-called emulsion oil consisting of waste oil B and main fuel oil A is formed using the moisture itself in waste oil B, and the emulsion fuel is ejected from the nozzle 29 and burned. .

着火が望ましい。 Any method may be used to ignite the injected fuel, but direct ignition using a so-called transformer is sufficient when the water content in waste oil B is 10 to 15% or less, and when the water content is higher than that, pilot ignition is used. is desirable.
又、廃油Ｂ内の混入異物に対しては、メツシユ
の比較的細かい複式ストレーナ２０を２段に設け

行なえる。(Effects of the invention) (1) In this invention, main fuel oil and waste oil are mixed before the inlet of the stem, and waste oil with a relatively high water content is emulsified together with main fuel oil in one combustion device. Because it is configured to burn this, it is possible to significantly reduce equipment costs compared to the conventional combustion equipment that has separate combustion equipment for waste oil and main fuel. There are no inconveniences when feeding a mixture of these, and waste oil combustion can be performed with less generation of dust.
