し壊れた時にも安定した燃焼を行うことができる。2. Description of the Related Art A conventional pot type oil combustor supplies fuel into a pot and supplies air from a number of air holes in a side wall.
The mixing of the fuel and air vaporized in the pot is promoted by various shapes of auxiliary members, and the mixture is burned in the pot and the combustion chamber. And unlike the evaporative burner, the pot type oil combustor produces a mixed gas of fuel and air while partially burning in the vaporizing part, and stable combustion even when the balance of air and fuel supply is slightly broken. It can be performed.

発生することがある。That is, when there is an excess of air with respect to the fuel, a large amount of air is supplied to the mixing portion of the fuel and the air to promote the mixing, so that the flame becomes small but stable combustion is possible. However, when there is a shortage of air, there is a shortage of air in the mixed portion of fuel and air, and combustion is performed with insufficient mixing, so that the combustion state deteriorates and a large amount of incomplete combustion gas may be generated.

ている。Conventionally, in a Bunsen burner in which a mixed gas of air and fuel gas is burned by adhering to a flame hole, the position of the flame does not change significantly due to a change in the amount of combustion or the amount of air. By monitoring the start of abnormal combustion. For this reason, even in a pot-type oil combustor, attempts have been made to stabilize the position of the flame by finely controlling the amount of fuel and air, and to detect an abnormality by the flame current.

置を用いないシステムの要望がある。By controlling the amount of fuel and air to specify the position of the flame, a pot-type oil combustor performs not only vaporization and mixing but also partial combustion inside the pot. Therefore, the height of the flame was not stable like the Bunsen burner, and the presence or absence of the flame could be detected by the flame current, but it was not possible to judge the combustion state. Because of this,
Pot-type petroleum combustors do not sufficiently cope with air shortages, and there is a demand for a system that does not use a flame detection device that performs safe operation immediately after incomplete combustion starts.

A bottomed cylindrical pot 3 having a hole 3 a formed therein, a combustion chamber 4 provided continuously above the pot 3, and a fuel pipe 6 for supplying fuel to the pot 3 via an oil amount adjusting means 5. The combustion blower 1 and the oil amount adjusting means 5 work together to change the air amount and the fuel flow rate, and the upper part of the gap between the blower cylinder 2 and the pot 3 is closed by a sealing plate 7. Further, in a pot type oil combustor in which a circular combustion support member 8 forming a gas flow path A is provided between the inside of the pot 3 and the side wall, the air hole 3a in the side wall of the pot 3 is lower than the combustion support member 8.

いる。The auxiliary combustion member 8 mounted above the inside of the pot 3 is formed in a circular shape, a combustion flame is formed upward from the side of the auxiliary combustion member 8, and the combustion blower 1 and the oil amount adjusting means 5 are interlocked. The amount of air and the flow rate of fuel are changed in such a manner that the positions where the combustion flames are formed are substantially the same without any significant deviation.

ずかである。During normal combustion, air is sent from the passing air hole 9 into the combustion chamber 4 and is mixed with the combustion gas and diffused. Therefore, the oxygen sensor 11 forming the oxygen concentration cell is formed. Since the oxygen exists in both the air inside the pipe 10 and the gas above the combustion supporting member 8, the electromotive force is slight.

火を行うものである。On the other hand, if the amount of air supplied to the pot 3 is insufficient, the mixing of the fuel gas and the air inside the pot 3 becomes insufficient, and this gas becomes a large flame when burning on the side of the auxiliary combustion member 8. For this reason, since the flame above the auxiliary combustion member 8 is filled with incomplete combustion gas and becomes oxygen-free gas with respect to the air in the pipe 10 containing oxygen, the oxygen sensor 11 is large. An abnormal combustion can be detected by generating an electromotive force. Therefore, the oxygen sensor 11
The warning signal is issued to the operator by the signal of, and the fire of the combustor is extinguished.

The maximum value of the oxygen sensor 11 is about 600 m
Since a large electromotive force of V is generated, and this increase in the electromotive force is determined to be an insufficient amount of air, an alarm is issued to a handler or the fire of the combustor is extinguished. Further, even if it is determined that the air is insufficient, when the combustion blower 1 can change the blowing amount linearly, the air blowing amount is increased and the output of the oxygen sensor 11 is monitored once. The fire of the combustor may be extinguished.

た。According to the pot type oil combustor, even if it is a burner which can completely burn even if the air is excessive, the filter may be clogged due to its characteristics, or the rotation of the combustion blower 1 may be poor.
In addition, when used in an intake / exhaust type oil combustor, when the intake / exhaust top is blocked with snow or ice and the amount of air is insufficient, abnormal combustion occurs and a large amount of incomplete combustion gas is generated. Further, even when abnormal combustion occurs and a large amount of incomplete combustion gas is generated, air is diffused in the exhaust gas, and it has been considered difficult to use the oxygen sensor to detect abnormal combustion. In the present invention, the start of abnormal combustion can be detected by the oxygen sensor 10 only by specifying the mounting structure and position of the oxygen sensor 10, and the safety of the pot-type oil combustor has been greatly enhanced.

By instructing the combustor to stop operating, serious troubles due to abnormal combustion could be prevented.
