Abstract

Various burners using firewood as fuel appear because of high oil prices. The burners have the disadvantage of having to input fuel more frequently than fossil fuel such as gas and oil. Firewood is input once and burned stably for a longer period of time by arranging a firewood input pipe vertically above a burning chamber, arranging firewood in a gravitational direction and burning the firewood from the bottom. Therefore, the firewood is burned uniformly for a long period of time. Air can be supplied to the firewood via two methods. One method of opening the top of the input pipe and lowering air to a burning position induces stable burning while effectively cooling the firewood inside the input pipe. But the method increases the possibility of backfire caused by a chimney effect if the input pipe is elongated. The other method of closing the top of the input pipe and supplying air upward can extend the length of the input pipe to a desired length but cannot adjust burning easily due to the generation of wood gas caused by the excessive pyrolysis of the firewood as burning heat is concentrated on the firewood input pipe right above and the firewood. A more stable burning environment is induced by installing an air supply pipe enveloping a certain region of the firewood input pipe right above the burning chamber having a burning heat concentrated thereon to supply outer air to the burning chamber after cooling the firewood input pipe by circulating the outer air along the air supply pipe. Moreover, the present invention can respond to additional supply of firewood by detachably adding a firewood input extension pipe to the firewood input pipe.

Description

{Uniform burning wood stove}

Firewood furnace with firewood, firewood boiler

The harmonious combustion devices that have disappeared from the surroundings due to the era of the high oil prices are appearing around again. Compared with combustion equipment such as gas oil, which can completely control and supply fuel, it is inconvenient to manually supply the fuel again frequently. In this case, instead of putting the entire harmonics into the combustion chamber, the gravitational tube is installed in the gravity direction, and a part of the harmonics is placed in the outside of the combustion chamber in a part of the outer cool area. And has a long burning time.

In practice, there are two methods of air supply: opening the top of the firewood inlet, burning the air from top to bottom, and burning the top and closing the top and supplying air from the bottom. First, the method of supplying air from above is easy to observe the stabilization of firepower and the appearance of fire because the air is supplied to the lower spot while cooling the upper firewood. However, if you try to put a long firewood by lengthening the firewood input pipe, it will become more and more communicative as the input port heats up, and the fire is backfired. When the second pipe is closed and the air is supplied by opening the lower part, it is possible to extend the pipe as long as the desired length. In this case, the heat of combustion rises up to heat the unburned part of the firewood. There is a side that is difficult to control output. In addition, the length of the fire input pipe is different according to the burning time required. The length of the fire input pipe of the present combustion device can not be changed when it is decided at the time of making.

The present invention solves the above problems and disposes a long fire-fighting pipe for injecting long firewood, which prevents accumulation of heat in the fire-fighting firewood part, thereby providing a stable combustion environment for a long time, Adjustable.

In order to attain the above object, an air supply pipe surrounding a certain area of a fire-fighting pipe projecting over a combustion chamber is disposed, and the outside air is circulated through an air supply pipe to cool the heat of the fire- Thereby preventing overheating of the pipe and stabilizing the fuel and stabilizing the output. In addition, it is possible to attach and detach the firewood extension pipe on the firewood supply pipe projected onto the air supply pipe, thereby attaching various firewood extension pipes as needed.

According to the present invention, since the entire length of the injection pipe is adjusted by the length of the injection pipe of various lengths, it is changed into the injection pipe of the length suitable for the burning time after the input of the desired one time, It is possible to stabilize combustion by preventing the overheating of the firewood located in the inside of the pipe, and also to make the amount of air supplied to the air supply pipe to be reasonably adjusted, thereby being a harmonious combustor capable of stable combustion for a long time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Fig. 1 shows a general woodworking injection pipe 1, a harmonics combustor in which a combustion chamber 2 and heat radiation communication are installed. Air is introduced through the upper side of the injection pipe 1 to cool down the firewood while passing through the firewood, and at the same time, it is supplied to the combustion chamber to be stably burned. At this time, the cross section of the firewood input pipe is in the shape of a circle, an ellipse or a polygon, and operates stably when the length of the firewood input pipe 1 is not long.

FIG. 2 is a perspective view of the fire-fighting apparatus according to the first embodiment of the present invention; FIG. 2 is a perspective view of the fire-fighting apparatus according to the first embodiment of the present invention; However, since the heat is generally raised, the combustion heat supplied to the firewood supply pipe and the firewood can not be sufficiently cooled to induce thermal decomposition of the firewood located in the firewood entrance and irregular wood gas generation.

In FIG. 3, an air supply pipe 6 similar to a double pipe is disposed in a fire input pipe located just above the combustion chamber where heat is concentrated, so that the fire supply pipe is cooled faster by the external inflow air, So that the heat to be externally diverted is transferred to the combustion chamber and concentrated to the most necessary place, so that it is possible to stabilize the internal firewood of the fire-fighting pipe and precisely control the supply amount of the regulated air. FIG. 4 is a perspective view of a firewood input pipe and an air supply pipe surrounding the firewood input pipe. In this case, the cross section of the air supply pipe is in the shape of a circle, an ellipse or a polygon, and the fire supply pipe 8 surrounds the air supply pipe 9 and the air supply regulating device 7 for regulating the amount of air supplied to the air supply pipe 9, The air supply amount can be adjusted by adjusting the air supply amount according to the rounding angle used in the old briquetting furnace or adjusting the air supply amount by sliding the rectangular plate. The arrangement and shape of the air outlet are configured in a shape suitable for the shape size of the combustion chamber, for example, at the air outlet 10 for guiding air into the combustion chamber. For the sake of convenience, a combustor with one furnace input tube is described, but the same principle applies to a furnace combustor employing two or more furnace input tubes. 5 is an actual photograph of a harmonious burner manufactured by arranging four air supply pipes in a harmonious burner having four firewood input pipes. Fig. 6 relates to a firewood supply pipe extension pipe. The length of the firewood supply pipe is preferably as short as possible, but a long fire-fighting pipe is required to secure a long burning time. In case of initial shipment, it is supplied to the pipe length of the appropriate length (11), and in addition to this, it is possible to prepare and insert various kinds of the pipe extension pipe (12) according to the shape of the pipe insertion pipe, It can be born. In the figure, only the extension of one step is drawn, but the extension of the second step and the third step is possible by the same principle.

The harmonics combustor according to the present invention can be applied to a variety of applications through a partial transformation to a harmonious hearth for heating air, a warm air blowing fan for generating warm air, and a harmony boiler for heating through water.
