Description

Indirect Charcoal Fire Box and Method for Manufacturing Charcoal}

The present invention relates to a carbon (charcoal) furnace device and a method for producing carbon, in particular to carbonized wood indirectly carbonized before the carbonized ash to produce the carbon wood liquor and at the same time effectively recover the wood vinegar generated in the carbonization process It relates to an indirect carbonization furnace apparatus and a method of manufacturing coal.

When the wood is heated in the air, the water in the wood evaporates first, and then heating, carbon, oxygen, hydrogen, etc. in the wood are combined with oxygen in the air to volatilize carbon dioxide and water, leaving only a small amount of ash. However, when the air supply is cut off and heated in a container with an outlet, it is not burned but spontaneously carbonized, and the cellulose, hemicellulose, and lignin that make up wood are decomposed to generate carbon, oxygen, and hydrogen. They are bound together by mutual affinity to form various carbohydrates, and then condensed and decomposed into complex compounds. Finally, the wood gas is recovered by cooling and purifying the discharged wood gas to produce the remaining charcoal.

In recent years, the anion generated by charcoal itself has been shown to be very beneficial to the human body by neutralizing the harm of cations generated in our body, and it has been proved to be very high in anti-corruption, far-infrared radiation, odor removal, and deodorizing effect. It is widely used for obtaining one effect.

In general, the pulverization method is a conventional method that has been used since the past, and the size of the tangama is not only large but time-consuming, but also the yield of the coal and the quality of the coal itself are low.

Recently, some mechanical carbonization furnaces have been imported or developed to make the pulverization, but since these fuels are directly fired, the fuel directly heats the wood, so that the wood is carbonized. Due to the uneven temperature at the upper and lower sides, the basic physical properties such as the hardness and adsorption power of coal are very low. Exhaust gas is not filtered and discharged as it is, causing pollutants. In general, since most of the carbonization furnaces are manufactured in large sizes and are expensive, they are difficult to diversify and efficiently use coals in farms.

The object of the present invention devised to solve the above problems is to increase the fuel efficiency by indirect heating type, do not adhere to the coal, and suppress the emission of pollutants by burning the exhaust gas, the price is low and standardized It is possible to produce large quantities of cheap and good quality coal by making farming supply type carbonization furnace device which is easy to move because it is adjustable in size.
