きるようになっている。The invention will now be described in more detail with reference to the illustrated embodiment.
A combustion device that mixes and stirs fuel oil, water, and emulsified *J# according to 1, and automatically supplies the round-hole fuel to the burner (3) under constant proportional control in response to load fluctuations in the boiler (2). In addition to (4), the combustion chamber (5) of the boiler (2)
), the discharge part (6) K oxygen detector (7) is arranged, and the cascade type indicating controller CII K W continued,
On the other hand, this cascade type indicating controller 01 is the boiler (2)
emulsified fuel flow meter C1 that is proportionally controlled to load fluctuations in
1l and a reverse converter a which controls the numerical value of this flowmeter OD in inverse proportion, and receives the standard value. This reverse converter αzFi When the emulsified melt is busy below a certain flow rate, the wind pressure will drop and the exhaust gas will not be discharged smoothly due to the influence of outside air, so in order to make the air volume slightly higher than the theoretical value of suitable combustion oxygen. This cascade type indicating controller 01 is connected to the air conditioner 0 and the inverter a4, and the rotation speed of the blower 09 motor (1e) that blows air into the grilling chamber (5) is determined by the intransitive clause 〒
It is now possible to

It is possible to calculate it as follows.

合に適する。The present invention is constructed as described above. An oxygen detector (8) is distributed to the discharge part of the boiler or heating furnace to constantly measure the amount of oxygen, and this measurement result is transmitted to the Fi converter (8).
(9) The first invention stores the cascade type indicating controller in advance and calculates the nine standard values through the cascade type indicating controller (1), and sends this calculated instruction to the inverter to control the motor. Therefore, the air volume is sent from the blower so that the amount of oxygen discharged from the exhaust section is always constant.In the case of this week's case, when there are few load fluctuations of the boiler or heating furnace, that is, the flow rate of emulsified fuel is Suitable when there are few changes.

硫黄酸化物がない。In the second invention, a measurement signal from an oxygen detector is input,
On the other hand, this measurement signal is calculated by converting the numerical value of the flow rate needle of emulsified fuel, which is always proportionally controlled in response to load fluctuations in the boiler, into a standard value that is made into an inversely proportional signal by a reverse converter, and this calculated signal is converted into voltage by an isolator. The rotation speed of the blower motor is controlled by an inverter. Therefore, the amount of air can be adjusted in accordance with the load fluctuations of the boiler or heating furnace, and the rotational speed of the motor is automatically adjusted at all times, and the amount of air from the blower is controlled to the minimum necessary, resulting in complete combustion with low oxygen and thermal efficiency. Also, nitrogen oxides,
No sulfur oxides.

出がスムーズに行なわれ燃焼効果を高めるもの〒ある。The value on the flowmeter indicates that the reverse converter is inversely proportional to the pressure, that is, in normal combustion, the amount of oxygen may be proportionally less at low temperatures, but in this state, the wind pressure in the exhaust section is insufficient. Since there is a risk that the exhaust gas from the exhaust part may not flow smoothly, an inversely proportional signal is sent to the cascade type indicating controller to prevent the air volume from decreasing.The signal is converted to the oxygen amount measurement signal and is used to control the motor and discharge the gas. There are some that allow gas to be discharged smoothly and enhance the combustion effect.
