What are the uses of charcoal?
Charcoal is a product obtained from various biomass raw materials after a series of reactions such as dehydration and thermal decomposition in a carbonization furnace, which has a wide range of uses in various industries and plays an important role in the development of human beings. So, what are the uses of charcoal?
Industrial use of charcoal
Charcoal is commonly used in the metallurgical and chemical industries. The pig iron smelted generally has a fine-grained structure, tight castings and no cracks. Pig iron produced with charcoal contains few impurities and is of good quality, so it is suitable for the production of high-quality steel.
In the production of non-ferrous metals, charcoal is often used as a surface flux, which has two advantages: firstly, it can reduce the splash loss of molten metal, and secondly, it can reduce the saturation of gas in the molten material. Charcoal is also used in the production of crystalline silicon, but the charcoal used for the production of crystalline silicon is of high quality and should not contain raw charcoal or excessive ash.
What are the uses of charcoal in agriculture field?
Charcoal can be used in agriculture to raise the ground temperature. When the charcoal powder is applied to the soil, the soil temperature can be increased due to the absorption of solar heat by the black charcoal particles, which promotes seed germination, improves germination rate and increases crop yield.
Charcoal can be used in agriculture to improve the soil. When the charcoal powder is applied to the soil, rhizobia can be generated on the surface of the charcoal, thus forming an agricultural soil suitable for plant cultivation and allowing the soil to be used continuously without loss of fertility.
Charcoal can be used as a slow-release agent for pesticides or fertilizers: The adsorption capacity of charcoal is used to maintain a balance between pesticide and organic fertilizer content, and this balance can be used to make pesticides or fertilizers released slowly in the soil.
In addition, charcoal can change soil acidity and alkalinity, increase soil CO2 content, adsorb harmful metals in the soil, and improve the vitality of soil microorganisms, etc.
Charcoal usage in daily life
People often use charcoal as a fuel for heating, cooking and barbecuing. In the past, people used to use the wood cut down directly as fuel, but the wood burned with big smoke and short burning time, so later people would make the wood into charcoal by charcoal making machine, especially the mechanism charcoal and various kinds of pressed charcoal. Because of its smokeless smell, high heat generation, low ash and long burning time, charcoal is becoming more and more popular among people.
Charcoal has numerous holes, which can absorb various substances such as odors and moisture. Charcoal can therefore help preserve food and can also be placed on refrigerators as a deodorizer.
In some countries, hookah smoking is a form of recreation, and hookah charcoal is an important fuel. Water pipe charcoal is a carbon block compressed from high-quality charcoal powder and is commonly available in round and square shapes.
