[0002]

2. Description of the Related Art A combustion apparatus combining a combustion apparatus for burning solid fuel such as firewood, coal or garbage with a fuel apparatus for burning fluid fuel such as gas or petroleum has been disclosed by the applicant as 2-5.
No. 214, Japanese Utility Model Application No. 3-53083, and the like, and as other known examples, Japanese Utility Model Publication No. Sho 52-46334 and Japanese Utility Model Publication No. Sho 56-20624 are known. The former uses preheating of an oil stove to incinerate refuse, and the latter directs the flame of a fluid fuel combustion burner composed of a gun-type burner directly to solid fuel to start burning solid fuel. After the ignition, the combustion of the fluid fuel combustion burner is stopped and only the blower is operated alone to forcibly blow the combustion air.

[0003]

[Problems to be Solved by the Invention] The disposal of garbage discharged from homes or waste such as furniture and home electric appliances has been highlighted as a social problem, and burning garbage at home is accompanied by a bad smell. There is a problem that incomplete combustion gas is discharged together with exhaust gas.

[0004] Further, in the co-combustion device which combines the solid fuel combustion device and the fluid fuel combustion device as in the present invention, it is general that an air intake for burning the solid fuel alone is provided at the lower portion of the combustion cylinder. Therefore, there is a drawback that ash is scattered from the air intake and odor is emitted.

[0005]

According to the present invention, a roster 2 is provided in the middle of a combustion cylinder 1, a solid fuel combustion section 3 such as firewood is provided on the upper part of the roaster 2, and a fluid is directed toward the solid fuel combustion section. A fuel combustion burner 4 is provided, and a baffle plate 5 having a non-perforated portion 5a and a perforated portion 5b is provided between the solid fuel burning portion 3 and the fluid fuel burning burner 4, and is used for fluid fuel combustion. When the burner 4 is operated, the perforated portion 5b of the baffle plate 5 and the fluid fuel combustion burner 4 are opposed to each other. When the fluid fuel combustion burner 4 is stopped, the non-porous portion 5a, the fluid fuel combustion burner 4 and Has a structure in which the air guide plate 5 is movable at a position where the perforated portion 5b is located below the rostr 2 opposite thereto, and the blower 6 continues to operate even when the burner 4 for fluid fuel combustion is stopped, so that the perforated portion 5b -Fired fluid fuel combustion device, characterized in that air is blown from the bottom to the lower part 2 One in which the.

When the air guide plate 5 is dish-shaped and a hole 5c is also formed in the upper edge portion, secondary air can be supplied to the upper portion of the solid fuel combustion portion 3 to contribute to complete combustion. It is.

[0007]

When a solid fuel such as firewood, coal, garbage or the like is placed on the upper part of the roaster 2 provided in the combustion cylinder 1 and the fluid fuel burning burner 4 directed to the solid fuel burning section 3 is operated, the fluid fuel burning burner 4 It is heated by the flame of the present invention, is ignited soon and continues self-combustion, and is used for heating or hot water supply.

After burning the fluid fuel combustion burner 4 for a certain period of time by the control mechanism, the fuel supply device such as an electromagnetic pump is stopped, and the air guide plate 5 is lowered, so that the non-porous portion 5a of the air guide plate 5 It moves to a position facing the burner 4 for combustion. At this time, since the blower 6 is set to continue operating even if the combustion of the fluid fuel combustion burner 4 is stopped, the wind hits the non-porous portion 5a of the baffle plate 5 to change the wind direction, and The air is supplied as combustion air from the located perforated portion 5b to the solid fuel combustion unit 3 and does not require a special air intake hole in the lower part of the combustion cylinder 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure will be described below with reference to the drawings showing an embodiment. Reference numeral 1 denotes a combustion cylinder of a combustion apparatus that uses both solid fuel such as firewood and fluid fuel such as petroleum. The solid fuel combustion section 3 is located above the
Having. Reference numeral 4 denotes a burner for burning fluid fuel such as petroleum, which is viewed from the side of the combustion cylinder 1 toward the solid fuel burning section 3.
The figure shows a pressure spray type burner.

Reference numeral 5 denotes a baffle plate provided between the solid fuel combustion unit 3 and the burner 4 for fluid fuel combustion. The baffle plate 5 is provided with a non-porous portion 5a and a perforated portion 5b in a vertical relationship. When the fluid fuel combustion burner 4 is burning, the air guide plate 5 is locked by the locking mechanism 7 at the upper movement position, and when the fluid fuel combustion burner 4 is stopped, the lock is released and the dynamic wind plate 5 is stopped. Is moved downward, so that the burner 4 for fluid fuel combustion and the baffle plate 5
a faces each other.

Reference numeral 6 denotes a blower for sending combustion air to the burner 4 for fluid fuel combustion. Even when the combustion of the burner 4 for fluid fuel combustion is stopped, the blower 6 is controlled to continue operating while the solid fuel combustion unit 3 is burning. I do.

Reference numeral 8 denotes a reset lever for manual operation when the air guide plate 5 is moved upward. When the reset lever 8 is moved upward, the air guide plate 5 is also moved upward, and the perforated portion 5b and the fluid fuel combustion The lock mechanism 7 is locked at a position where the burner 4 faces the burner 4, and the switch 9 is turned on to enable the operation of the burner for fluid fuel combustion.

Numeral 10 is a fuel supply device such as an electromagnetic pump for sending fuel to the burner 4 for fluid fuel combustion. A switch for switching the operation for a fixed time only when the solid fuel is ignited or for continuously performing fluid fuel combustion is provided by a switch. 9 and a controller not shown.

Numeral 11 designates a solenoid interlocked with the fuel supply device 10, and the solenoid 1 operates when the fuel supply device 10 is stopped.

Reference numeral 12 denotes a slide rod for vertically guiding the air guide plate 5, reference numeral 13 denotes an exhaust tube for discharging exhaust gas from the combustion tube 1 to the outdoors, and reference numeral 14 denotes a lid used for charging solid fuel from above the combustion tube 1.

If the shape of the baffle plate 5 is dish-shaped, holes 5c can also be formed in the peripheral portion, so that air can be blown from the periphery of the baffle plate 5 to the combustion chamber. In particular, when the hole 5c is formed in the upper edge portion, it is possible to supply the upper portion of the solid fuel combustion section 3 as secondary air.

[0016]

[Effects of the Invention] The present invention having the above configuration and operation has a structure suitable for combined use of solid fuel such as firewood and fluid fuel such as petroleum, and mainly burns firewood and the like. Sometimes,
By moving the baffle plate 5 upward at the time of ignition, the flame of the fluid fuel combustion burner 4 is directly applied to the solid fuel, the ignition is reliably performed, and after a certain time, the operation of the fluid fuel combustion burner 4 is stopped. The wind plate 5 can be moved downward to eliminate the influence of flame, soot, ash, etc. on the burner 4 for fluid fuel combustion at the non-porous portion 5a, and does not cause damage or blockage of the burner 4 for fluid fuel combustion. Things.

Also, even if the operation of the fluid fuel combustion burner 4 is stopped, the operation of the blower 6 is continued.
The air from the blower 6 passes through the perforated portion 5b and is supplied as combustion air from the lower part of the rostrus 2 to the solid fuel combustion unit 3 and contributes to the complete combustion of the solid fuel. Since no holes are needed elsewhere, no air leaks or ash splashes during combustion.

If the shape of the baffle plate 5 is made dish-shaped and a hole 5c is also formed in the upper edge portion, the combustion air is uniformly supplied from the periphery of the baffle plate 5 and the secondary combustion of the solid fuel is performed. Is suitably performed.
