Abstract

<P>PROBLEM TO BE SOLVED: To solve problems of a conventional stove or the like wherein it was difficult to use undried wood or a conifer as fuel since a massive amount of smoke is generated when used, and bark or the like discharged in a lumber yard or the like was unusable as fuel. <P>SOLUTION: Outer side containers are equipped on an outer side of a combustion chamber container to vertically form combustion air chambers, a temperature of air of the combustion air chamber is raised to a high temperature by combustion of combustibles in a combustion chamber, and generation of smoke is prevented by blowing the high temperature air on combustion gas including smoke components and carrying out complete combustion. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a combustor that can be easily burned even when undried firewood, hard-to-burn conifers or bark are used as fuel.

  As a conventional combustion system such as a wood-burning stove, there has been a system called warm burn that warms outside air with combustion heat and sends it to a secondary combustion chamber to promote complete combustion. A method of removing smoke using a catalyst or the like is also known.

Indication of invention

Problems to be solved by the invention

  However, in the case of the above combustor, when the amount of oxygen supplied to the combustion gas generated immediately after the fuel is supplied is insufficient, smoke is generated as a result, or fuel with a high water content is supplied. Could not burn.

Means for solving the problem

  In order to achieve the above object, the present invention divides the air sent into the combustion chamber into an upper part and a lower part and makes it possible to adjust the air inflow amount in the upper and lower directions so as to completely burn the combustible gas by injecting hot air into the combustible material. For example, when a new combustible material is introduced into the combustion chamber during combustion, a large amount of combustion gas is generated from the combustible material that has been introduced due to the high temperature in the combustion chamber. However, if the lower combustion air inflow regulating valve is closed at this time, the air supply to the lower portion of the combustion chamber is stopped, and the generation of combustion gas is remarkably reduced, resulting in low heat. If the upper combustion air inlet valve is open at this point, the air that has become hot in the upper combustion air chamber is supplied only to the upper combustion chamber, and the combustion gas generated near the lower combustion chamber rises to the upper combustion chamber. When this happens, the combustion gas can be burned to eliminate smoke.

The invention's effect

  In this way, by adjusting the upper and lower air flow rates according to the introduction of combustible materials, combustion can be performed without producing any smoke, and the combustion speed can be adjusted freely.

  In addition, in the case of initial ignition, if an old newspaper is lit and put into the combustion chamber and then something like wood chips is inserted from there, the air in the combustion air chamber becomes hot only with the heat that the old newspaper burns. As the hot air is jetted immediately and the wood chips burn out, the ignition can be done very quickly and easily.

  In order to use this combustor efficiently, as shown in FIG. 3, the inlet 15 is provided at the upper part of the combustor, the dust collector 17 is provided at the upper part thereof, and the exhaust discharge ejector 18 is provided at the upper part thereof. Dust efficiency and combustion efficiency can be increased.

  Hereinafter, based on an accompanying drawing, a combustor concerning an embodiment of this invention is explained in detail. An outer container 1 is provided with a certain gap provided outside the combustion chamber container 2, and a combustion air chamber is formed between the combustion chamber container 2 and the outer container 1 by sealing the upper and lower portions of the gap. In order to divide the air chamber into upper and lower portions, a combustion air chamber upper and lower partition 8 is provided to constitute an upper combustion air chamber 5 and a lower combustion air chamber 11, and air is blown from the upper combustion air chamber 5 to the upper portion of the combustion chamber 4. A plurality of upper combustion air circulation holes 3 are provided, and a plurality of lower combustion air circulation holes 10 for blowing air from the lower combustion air chamber 11 to the lower part of the combustion chamber 4 are provided. And an upper combustion air inflow adjustment valve 6 and a lower combustion air inflow amount adjustment valve 12 which can adjust the flow rate of the upper and lower air respectively, and are provided with a combustion chamber. Blower 1 that can send air into 4 A combustibles combustor comprising a.
