Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combustion device capable of combined combustion of a fluid fuel such as gas or oil and a solid fuel such as dust, coal or firewood.

[0002]

[Prior art]

 Although there are not many known examples of a combustion device that combines a combustion device that burns solid fuel such as firewood, coal, or garbage, and a device that burns a fluid fuel such as gas or oil, the applicant is No. 2-5214.・ Proposal of Japanese Utility Model Application No. 3-53083, and other publicly known examples are Japanese Utility Model Publication No. 52-46334 and Japanese Utility Model Publication No. 56-20642.

[0003] One of the conventional examples is equipped with an incinerator that incinerates dust using the residual heat of an oil stove. In addition, for burning liquid fuel such as gun type directly to dust and solid fuel. Ignition combustion is performed by directing the flame of the burner. In the case of solid fuel single combustion, after the ignition, the combustion of the burner is stopped and only the blower is forcibly blown to continue combustion. Naturally, when solid fuel is not used, the burner operates independently to burn the fluid fuel.

[0004]

[Problems to be solved by the device]

 When solid fuel such as firewood is ignited once, ash accumulates in the combustion cylinder, and the fuel becomes smaller and smaller, so it is necessary to open the door from time to time to replenish the solid fuel. When opened, it has the drawbacks that ash powder scatters and the odor generated from the combustion products leaks out.

Further, when the solid fuel is burning normally and with a large thermal power, if a burner for fluid fuel combustion is also used, there is a problem that the combustion cylinder is likely to have an abnormally high temperature and is dangerous.

[0006]

[Means for Solving the Problems]

 According to the present invention, a gust 2 is provided in the middle of the combustion tube 1, a combustion part 1a for solid fuel 3 such as firewood is provided on the top of the gust 1, and a burner 4 for fluid fuel combustion is provided toward the combustion part 1a. In a firewood combustion / fluid fuel combustion device, which is extremely rare, a door 5 for introducing firewood and a switch 6 that responds to opening and closing of the door 5 are provided on one side of the combustion cylinder 1 to burn the burner 4 when the door 5 is opened. It was a fluid fuel combustion device that also stopped firewood, and when the door was opened to replenish firewood, the ash did not fly out due to the momentum of the burner flame.

Further, a temperature sensor 7 is provided on a side portion of the combustion cylinder 1, and when the temperature of the combustion cylinder 1 is higher than a certain temperature during burning of wood, the burner cannot be combusted, resulting in an abnormally high temperature. Was prevented.

Further, the blower 4a for combustion, which is a component of the burner 4, is operated even when solid fuel such as firewood is burned to enable supply of combustion air, and the air volume of the blower 4a when the door 5 is opened is reduced. Since it was configured to be cut or cut, it was possible to prevent ash from popping out when the door was opened.

Further, since the blower 9 is provided at the exhaust port 8 connected to the combustion cylinder 1 and the blower 9 is operated when the door 5 is opened or the air volume is increased, even with this structure, ash is generated when the door is opened. Can be prevented from popping out.

[0010]

[Action]

 When the burner 4 is operated by placing the solid fuel 3 such as firewood, coal and dust on the upper portion of the rostrut 2 provided in the combustion cylinder 1, the solid fuel 3 is ignited and self-combustion starts. Then, once ignited, the burner 4 is stopped by the control mechanism and the operation of the blower 4a for combustion continues, so the combustion air is sent to the combustion section 1a of the solid fuel 3 and the solid fuel 3 is discharged. Combustion continues normally. Incidentally, it is naturally possible to stop the combustion of the burner 4 and burn the solid fuel 3 by itself, or burn the burner 4 for fluid fuel combustion in an independent operation without introducing the solid fuel 3.

Next, when the solid fuel 3 burns and the volume decreases, and the door 5 is opened when replenishment is desired, the burner 4 is stopped if the burner 4 is operating at that time, while the solid fuel 3 is burned alone. If it is baked, the air volume of the blower 4a for combustion is reduced or cut. Further, by providing a blower 9 at the exhaust port 8 to increase the air volume in conjunction with the operation of the door 5, there is an action of preventing ash from popping out when the door 5 is opened.

Further, when the combustion of the solid fuel 3 and the combustion of the burner 4 are combined to raise the temperature of the combustion cylinder 1 to a certain temperature or higher, the temperature sensor 7 senses the temperature and the operation of the burner 4 is stopped.

[0013]

Reference numeral 5 denotes a door for opening firewood, which is provided on one side of the combustion cylinder 1 so as to be freely opened and closed.

A switch 6 is provided in the vicinity of the door 5 for throwing in the firewood. In response to opening / closing of the door 5, if the burner 4 is operating at that time, the combustion of the burner 4 is stopped and the solid fuel 3 If the blower 4a for combustion is operating during combustion, the rotation is reduced and the air volume is reduced or stopped. Further, if the exhaust port 8 of the combustion cylinder 1 has an exhaust blower 9 as described later, the switch 6 controls the blower 9.

Reference numeral 7 denotes a temperature sensor provided outside the proper position of the combustion cylinder 1 so that when the temperature of the combustion cylinder 1 becomes an abnormally high temperature, the burner 4 for fluid fuel combustion cannot perform simultaneous combustion. The combustion of the corner 4 is stopped. Reference numeral 8 is an exhaust port for discharging the exhaust gas generated in the combustion cylinder 1 to the outside, and 9 is a blower connected to the exhaust port 8. This blower 9 is not a necessary part, but is operated during combustion of solid fuel 3 such as firewood to promote exhaust, or when the door 5 is opened to increase the air flow, the flow toward the exhaust port 8 direction. Has a role to prevent ashes and the like from being forced out of the opening of the door 5 by being forced.

Reference numeral 10 denotes a tray provided below the roastle 2, which is used when the ash of the solid fuel 3 is dropped from the roostle 2 and is collected and then discharged to the outside for disposal. Reference numeral 11 denotes a secondary combustion chamber formed in the combustion cylinder 1, and the combustion gas that has been substantially burned in the combustion section 1a is completely combusted in the secondary combustion chamber 11. Reference numeral 12 is a filter provided in the secondary combustion chamber 11, and this filter 12 catches that ash flows toward the secondary combustion chamber 11 side and is discharged through the exhaust port 8 depending on the quality of the solid fuel 3. It can be stored at the bottom of the combustion chamber 11. Incidentally, it is desirable to attach a sensor for detecting the clogging state of the filter 12, and it is possible to issue an alarm or stop the combustion by the sensor.

Reference numeral 13 denotes a fuel supply device such as an electromagnetic pump for sending fuel to the burner 4 for burning the fluid fuel, which is operated for a fixed time only when the solid fuel 3 is ignited. Further, when the solid fuel is not burned, the fluid fuel is burned continuously. At this time, the operation is switched by switching a switch (not shown) or by the controller 14.
