JPS6064109A - Combustion method of emulsion oil - Google Patents

Abstract

PURPOSE:To speed up the combustion of emulsion oil, by making the same burn within a space to which an electric field is bestowed. CONSTITUTION:A plate 1 made of aluminum prepared is grounded. A dotted electrode 2 is provided at a position 40mm. above the plate 1 and AC voltage of 50Hz is applied to a space between the position and the ground through a transformer 3. A period of time until combustion is completed has been measured by putting 10g of emulsion oil to be made by adding water to light oil so that moisture content becomes 20% within the plate 1. When oil is made to burn without applying the voltage to the electrode 2, though the light oil burns in 120sec, 305sec are necessary in case of the emulsion oil. Even if, however, it is the emulsion oil the voltage of 3.0kV is applied to the electrode 2. It is burnt in 96sec. In addition to the above, when the voltage is raised, combustion period of time is shortened all the more and when the voltage of 15kV is applied, the combustion period of time is reduced to 44sec, that is, 37% of that available at the time of nonapplication of the voltage to the light oil and 14% of that available at the time of nonapplication of the voltage to the emulsion oil.

Description

【発明の詳細な説明】 従来から乳化油は燃焼効率を高め、煤塵を減少させる手
段として知られ、使用されている。DETAILED DESCRIPTION OF THE INVENTION Emulsified oil has been known and used as a means for increasing combustion efficiency and reducing soot and dust.

しかし乳化油は、油中に水を混入しているのだから当然
燃焼は緩慢であり、同一熱出力ン得るためには通常の油
を使用する場合に比べてより大ぎな燃焼室を必要とする
。また水の蒸発ｒａｐＰ。However, since emulsified oil contains water, it naturally burns slowly, and in order to obtain the same amount of heat output, it requires a larger combustion chamber than when using regular oil. . Also water evaporation rapP.

に消費される熱量が相当に大なるため燃焼温度が低下す
るので、高温を必要とする場合特に高圧ボイラ等には使
用することができない。Since the amount of heat consumed is considerably large and the combustion temperature is lowered, it cannot be used in cases where high temperatures are required, especially in high-pressure boilers.

A dot-shaped electrode 2 is provided at a position of 40 nodes above this plate, and a transformer 3 is connected between this point and the ground for 50H.
Apply an AC voltage of z.

この皿１内に、軽油に水を含水率２０％となるよう加え
てなる乳化油１ｏ９を入れ、燃焼終了までの時間を測定
した。Emulsified oil 1o9, which is made by adding water to light oil to give a water content of 20%, was placed in this dish 1, and the time until the end of combustion was measured.

Burns in seconds. When the voltage is further increased, the combustion time is further shortened; when 15 KV is applied, the combustion time is 44 seconds, or 37% of the time when no voltage is applied for light oil, and 14 seconds when no voltage is applied for emulsified oil.

れる。Further, in this experimental example, the frequency of the power source was 50 Hz, but even if the frequency is direct current or other frequency, the combustion promoting effect can be obtained by applying an electric field in the same manner as above. In this case, as the frequency increases, the 1”-combustion promoting effect increases, and l
It reaches its maximum around KHz and tends to gradually decrease thereafter. Therefore, by using a frequency below 1.5-2 KHz, the burning rate of emulsified oil is significantly increased. Therefore, a large amount of combustion per hour, that is, a large heat output can be obtained with a small combustion chamber. Moreover, the unburned fuel becomes minimal, the calorific value increases, and the combustion temperature rises. Therefore, the microscopic water particles that are a characteristic of emulsified oil induce the so-called water gas reaction,
A significant increase in combustion efficiency is obtained. Furthermore, higher combustion temperatures can be obtained compared to when using 100% fuel.

したがって本発明は一般燃焼を必要とする場合は勿論、

有利となるものである。Therefore, the present invention is applicable not only when general combustion is required, but also when general combustion is required.
This is particularly advantageous in large power generation boilers that use large amounts of fuel.
