。Problems to be Solved by the Invention The emulsion combustion apparatus described above requires excessive equipment costs and installation space. In particular, in small boilers, due to their structure, the spacing between water pipes is narrow, making it impossible to use fuels that produce a large amount of soot and smoke, and the heat transfer area is small and 02 control cannot be performed, resulting in high NOx levels, so heavy fuels cannot be used.
又重質油燃料の燃焼には、加熱器等付属品が大きくなる
等の理由から軽質油の燃焼を行っている。Furthermore, when burning heavy oil fuel, light oil is used because accessories such as heaters become bulky.

特徴がある。Effects of the Invention According to the device of the present invention, water can be supplied to the emulsion mixer using the pressurized water supply water of the boiler, so there is no need for a special water supply device for generating emulsion fuel, and therefore the entire device can be It can be made compact, and the pressure of pressurized water can be maintained by using a pressure accumulator even in small boilers, which have a small amount of water and require frequent water injection and stop when using steam.
Furthermore, by using an emulsion mixer, a pressure accumulator, and a constant flow valve, fuel oil and water are supplied at a predetermined ratio, so that it can be used in a small boiler for emulsion combustion capable of burning heavy oil.

との対応を更にスムースにすることができる。Nozzle (3) attached to the furnace mouth (2) of the boiler can (1)
When fuel is injected and combusted, heated brackish water is separated by a brackish water separator (4), and steam is supplied to the load side from a steam port (5). From the oil supply pipe (6) to the emulsion mixer (7)
), the fuel oil pressurized by the injection pump (8) flows through the oil pipe (
9), it is sent to the nozzle (3) by the operation of the solenoid valve (10) and is combusted. When the load side is less than the steam generation capacity, an increase in pressure inside the can is sensed and the solenoid valve (10) is closed to stop combustion. The pressure gradually decreases, and when it reaches the set low pressure, combustion begins again. In this way, normally the load is dealt with by intermittent combustion, but the device of the present invention uses a solenoid valve (10') to control the low combustion nozzle (3'), which has a smaller amount of fuel than the nozzle (3). If controlled, the response to the load can be made even smoother.
噴燃ポンプ（８）の吐出量はノズル（３）あるいは低燃

しエマルジョンミキサー（７）を経由する管路を循環す
る。The discharge amount of the fuel injection pump (8) is larger than the amount of fuel injected from the nozzle (3) or the low combustion nozzle (3°), so even during combustion, when combustion is stopped, the entire amount of excess fuel oil is transferred to the relief valve (1).
1), joins the oil supply pipe (6) at the return pipe (12), and circulates through the pipe line passing through the emulsion mixer (7).

、停止が頻繁に繰り返される。Also, when the liquid level in the can decreases due to the use of steam, the water level detector (13) issues a command to pressurize water from the water supply pipe (14) with the water supply pump (15), and the discharge pipe (16) and electromagnetic It is injected into the can body (1) via the valve (normally open) (17) and stopped as the water level rises. The internal pressure of the can body (1,) is 5 to 10 kg/c+j, and the injected water is pressurized to a pressure higher than this. Since the amount of water stored in a small boiler is small, such water injection and stopping are frequently repeated as steam is used.

Since air is sealed in the upper part of the pressure accumulator (21) via the diaphragm (22), the pressure of the stored water is maintained even if the pressure in the branch pipe (18) decreases due to the stoppage of the water supply pump (15). I'm so attached to you.

The stored water can be injected into the emulsion mixer (7) via the emulsion mixer (7).

いずれも流入しない。A circulator consisting of an emulsion mixer (7), a fuel pump (8), an oil pipe (9), a relief valve <II), and a return pipe (12) circulates emulsion fuel at a constant ratio when it is rich. When the solenoid valve (10) is closed, neither fuel oil from the fuel supply pipe (6) nor water from the constant flow valve (24) flows in.
電磁弁（１０）が開くと該循環路から所定比率のエマル
ジョン燃料が供給されて燃焼し、一方該循環路には燃料
油と水が所定比率で供給されているのでエマルジョン燃
料の構成、比率は変化しない。When the solenoid valve (10) opens, emulsion fuel is supplied from the circulation path at a predetermined ratio and burned. On the other hand, since fuel oil and water are supplied to the circulation path at a predetermined ratio, the composition and ratio of the emulsion fuel are It does not change.

所定比率に変っていく。If the circulation line consists only of fuel oil, use the solenoid valve (
When 10) is opened, first, only the fuel oil is ignited, and as the fuel is added, an emulsion with a higher moisture content is gradually burned, and the ratio changes to a predetermined ratio for a while.
又燃焼中に水の注入を止めるとこの逆に暫時にして燃料
