What Is Wood Fuel?

Charcoal, a fuel name. It is the dark brown or black porous solid fuel that remains after wood or wood raw materials are incompletely burned or pyrolyzed under the condition of being isolated from air.

The main component of charcoal is carbon,

There are two kinds of methods:

(1) Kiln firing method: build a kiln with soil, fill it with wood, and burn it from the kiln door or fire door to keep the wood in the kiln.

Can be divided into:

Hard broad charcoal. Hardwood

Charcoal products are mainly divided into

Metallurgical industry

In the past, charcoal was used to smelt iron ore. The pig iron smelted from charcoal and coke has different structures and mechanical properties even though it has the same chemical composition. The pig iron smelted with charcoal generally has a fine-grained structure, compact castings, and no cracks. The pig iron produced with charcoal contains less impurities and is suitable for producing high-quality steel. Because charcoal is reducing, it can be used in the metallurgical industry to reduce ore and smelt metals.

In the production of non-ferrous metals, charcoal is often used as a surface flux. When non-ferrous metals melt, the surface flux forms a protective layer on the surface of the molten metal, separating the metal from the gaseous medium, which can reduce the splash loss of the molten metal and reduce the melting. The saturation of the gas in the water.

A large amount of charcoal is also used in the production of crystalline silicon. The charcoal used for the production of crystalline silicon should not contain a green carbon head and excessive ash.

2. Carburizing agent manufacturing

All steel products that require high hardness and wear resistance on the surface and good toughness in the center should be carburized. The carbonaceous mixture used to carburize steel products is called carburizing agent. The carburizing effect of pure charcoal is poor. Therefore, charcoal is often used as a raw material, and a certain amount of contact agent is added to make a carburizing agent.

3. Carbon disulfide production

Charcoal is the best raw material for making carbon disulfide. The charcoal used to make carbon disulfide should be hard, large in volume, small in ash and moisture content, and high in fixed carbon content.

It takes about 0.5 tons of charcoal to produce 1 ton of carbon disulfide.

4. Pressing of charcoal bricks

The transportation of crushed charcoal is very inconvenient and the use is also limited. The method of pressing charcoal bricks can make the small value charcoal into a high-quality fuel. Charcoal bricks have the advantages of low hygroscopicity and water absorption, high specific gravity and high heating value, and have high mechanical strength during use. Calcined charcoal bricks are smokeless and do not generate charcoal dust during combustion. Charcoal bricks can be used in metallurgy and mobile gasifiers.

5.Charcoal Desiccant

It is composed of several kinds of natural minerals. It is non-toxic and harmless and is a degradable and environmentally friendly desiccant. The moisture absorption rate is over 50%.

6. Medical value

Charcoal can cure the following diseases:

1) Swallow gold, silver, copper, and iron into the abdomen by mistake. Burn red with charcoal, simmer into fines while hot, and drink the decoction. If it is not effective, scrape the three charcoal powders, transfer it to the well water, eat it if it is invalid, and finally discharge the mistakenly swallowed things.

2) The pharynx suddenly stalks. Make pellets with charcoal powder and honey, mix and drink.

3) White tiger wind disease (bone joints are bitten by something, and the painful place may be erratic). Five litres of charcoal ash, one litre of earthworm feces, seven twists of safflower (one twist, pinched by two fingers), boil them together, stir them with vinegar, wrap them with old cloth, and iron the pain while hot .

4) Blood under intestinal wind. Three dollars of tight charcoal and five dollars of burnt ash were burned together for research. The three dollars for each serving were taken at five times, and the rice soup was delivered. Tianming served again. Avoid greasy.

5) Soup fire burns. Mix with charcoal and sesame oil.

6) White scabies. Use charcoal to burn red, put it in boiling water, and warm washing is effective.

7) Wet scrotum. Rub the affected area with charcoal and perilla leaves. ^[2]
