Abstract

PURPOSE:To facilitate ignition by an assistant burner, and to stabilize combustion, by intermittently feeding a specified rate of fuel onto a fire grate, and by feeding the air into a combustion chamber from the nozzle holes of a grate, in a combustion apparatus for which woody fuel such as sawdust is utilized. CONSTITUTION:A motor 13 is driven intermittently properly and feeds fuel of woody dust particle such as sawdust, intermittently into a combustion chamber B from a fuel tank A by a specified rate. The fuel fed into the furnace is divided into two by screw feeders 12a and 12b, and is accumulated in two heaps on a grate member 13. The fuel can be very easily ignited to burn when the air is fed into the furnace by a fan 3 from the nozzle holes 222a of a grate 222, passing through an air conduit pipe 221, and an assistant burner 25 is ignited. When the temperature in a combustion chamber B reaches a preset temperature, a temperature sensor senses it to stop the assistant burner to burn. With such an arrangement, proper combustion can be continued in a burner for a long time.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of burning wood-based fuel such as sawdust and a combustion device thereof, and in particular, it is easy to slowly ignite the fuel, and it is also efficient to burn wood waste such as waste sawdust. , burn hygienically for a long time,
I am interested in a combustion method and a combustion device that can maintain appropriate combustion quality.

In recent years, there has been a call for efficiency and labor savings in all types of persimmons, and the fuel used for dry-water boilers and other equipment is also being reconsidered from this perspective. For example, in the past, #1 greenhouses, such as greenhouses for cultivating shiitake mushrooms, shimeji mushrooms, nameko mushrooms, etc., were constructed using fire-fired greenhouses that used drought boilers, and their thermal efficiency and greenhouses were improved. Due to its advantages such as .

However, these petroleum-based fuels are relatively expensive and require high fuel consumption, so 4111 T-crystalline water boilers were developed that did not use these fuels for 1ψ, but used Sea Ogayaura Hada as fuel. There is.

However, these wood waste materials from 1 and 8 Ogaya are often damp and difficult to ignite and burn, so they are burnt using kerosene burners, etc. I'm really strong.

Therefore, it is easy to burn incompletely, and since the cod continues to be cooked with 1 oil/kuna, the consumption of these is still large.
If it is disposed of, % of the fuel is used at night, so
This can lead to problems such as not being able to get enough sleep.

Therefore, in consideration of the above facts, the present invention utilizes wood-based fuel from sawdust temples to reduce the fuel cost by approximately +rri L1, and the stone fire for the fuel is also made of pipe shafts, making it efficient and efficient. To provide a method for burning wood yarn fuel and a combustion device H for the same, which can burn the fuel intermittently and under its own weight to a combustion chamber at constant loss, and can obtain cotton in an appropriate combustible state for a long time. is l

Guide tubes 21a and 21b connected to 14b are provided,
The water is divided and supplied onto the water droplet member 2 placed on the water droplet 23.

The loss dollar member 22 includes an air supply path 221 and a loss dollar 222.
As shown in FIG. 3.4, the blower 3 is connected to the air blower 221 and the four-piece plate 22'A. The above-mentioned divided IJ: is formed to forcefully blow air to the fuel to be covered, and the shielding plate 223 prevents fuel, combustion ash, etc. from scattering into the smoke pipe.

Note that the water loss dollar 23 is a water droplet 23 provided along the inside of the casing 2! 7524 and the water channel 42 in the boiler body C described later, it is used as an extremely effective heat exchanger.

In addition, an auxiliary combustion burner 25 is disposed below the water burner 23, which makes the fuel combustible at the Hanawa crater, and when the fuel starts to burn sufficiently, it causes a rise in temperature within the combustion chamber 1. A temperature sensor 26 is provided to detect the temperature, and the auxiliary combustion burner 25 is stopped unless the temperature inside the combustion chamber B reaches the set temperature. (It is detected as above, and the auxiliary burner 25 is activated.)

In addition, an inlet [127] for wood-based solid fuel such as a 11kl engine is provided in the casing 2;
It is also used for combustion along with wood-based granular fuel.

Air is sequentially blown through the water channels 411 and 412 around them, exchanging heat with the water in the water channels 42 around these IJn, and generating tvh output 1.J4.
+1111 W No. 1 from 13. +V! (Suddenly) Q4 chapters were written, 1 Gen (1 and 1), and 1J with Hizou.

The water in the water channel 42 is absorbed from the water port 43a of the armpit body C, and is also absorbed into the water channel 24.4.
The water circulates through the interior of the water heater 2, etc., and is supplied as dry water to the floor heating 48, etc., from an outlet 43b provided above.

Next, the operation of the wet water boiler constructed as above will be explained.

First, wood-based powder fuel such as sawdust is put into the fuel tank A. The fuel is supplied to the respective discharge ports 1 through the screw feeders 12a and 12b in opposite directions by the drive of the motor 13.
41L and 14b, and is dividedly supplied onto the Losdol member 22 in the combustion chamber B via the guide tubes 21a and 21b.

Incidentally, since the motor 13 is operated intermittently as appropriate, it is possible to intermittently supply a desired amount of fuel into the combustion chamber B, thereby making it possible to automatically carry out long-term combustion.

In addition, since the fuel is supplied in two parts as mentioned above,
Two peaks are placed on the Rossdol member 13, and air is supplied from the blower 3 to the Rossdol 2 via the WT 221.
Since the fuel is sufficiently supplied from the nozzle holes 222a of 22, it is extremely easy to ignite and burn the fuel, and the fuel is completely combusted and becomes waxy.

That is, when the auxiliary combustion burner 25 is ignited, even slightly damp fuel is easily ignited, and after ignition, it continues to burn reliably until the fuel runs out.

Further, when the fuel reaches a certain combustion state, the humidity in the combustion chamber B reaches the set temperature L1, which is detected by the temperature sensor 26 and the auxiliary burner 25 is stopped +1-.

However, as mentioned above, since sufficient oxygen is supplied to the fuel, a stable combustion state can be maintained with the pre-fuel Mf.

Next, the smoldering air in the combustion chamber B is directly exchanged heat with the water in the water channel 24 of the first combustion chamber B, and is also transferred from the first smoke chamber 41a to the first smoke chamber 411 to the second combustion chamber 411 in the boiler main body C. Smoke chamber 41b→
When the smoke chamber 412 is sent to the eighth smoke chamber 410, heat is exchanged with the water in the surrounding water channel 42, so that the combustion heat can be used extremely effectively.

In this way, a predetermined amount of fuel is intermittently supplied and the fuel is reliably combusted, so that a stable state of combustion can be maintained for a long period of time, and hot water at a constant temperature can be heated for a long time. It is something that can be reconciled.

In this embodiment, the screw feeder is configured with a spiral plate shape, but the present invention is not limited to this, and rod-shaped bodies may be arranged in a protruding manner in a spiral shape, that is, toward the discharge port in the opposite direction. Any device may be used as long as it can transfer fuel, and although the present invention is applied to a drought boiler, it should be noted that the combustion method and apparatus according to the present invention are not limited to these applications. Needless to say, the specific structure of each part, such as the structure of the rostrum part, the number of rostrums disposed, the number of fumarole holes, etc., will achieve the above-mentioned purpose, function, and effect of the present invention. They may be determined in any way within the range.

-11- As mentioned above, as in 1JJL, the present invention provides that fuel is intermittently supplied to the Rosdol in a fixed amount at a time, and air is supplied to the visiting fuel from the blowholes penetrated through the Rosdol. Since the auxiliary burner is supplied, it is easy to control the fire, and even if the auxiliary burner is stopped after the ignition, a stable combustion condition can be maintained, and the auxiliary burner allows the use of commercially available fuels such as kerosene. It is also useful to minimize the consumption of road materials, therefore, it is possible to effectively utilize all the road materials (such as one-shot wood, sand, etc.) and save labor. ! Also, add fuel to 2
By supplying the fuel in parts to the Rosdol tank, it will be easier to ignite and burn it, and it will be more sanitary without causing complete combustion. For example, 11++ can be intermittently supplied to the combustion chamber at >i l−,
It is suitable as a heat source for warm kitchens such as Ichitei houses and wet kitchens that require burning during the night time, and the problems mentioned above that occurred with this yuzu burning method and device i't. I have no choice but to say that this is an excellent VCF invention that solves the problem extremely simply and ineffectively.
