Ways To Ensure Charcoal Efficiency

The charcoal will last longer if used properly and of high quality for its intended purpose. Charcoal quality may be specified and measured in a variety of methods, the majority of which are derived from the various end-use criteria. In most cases, efficiency in usage implies transmitting as much of the heat content of the charcoal as possible to the item to be heated, whether it's water for cooking, the air in a room, or the charge in a blast furnace. The use of appropriately constructed charcoal-burning equipment is critical to efficiency.

Most of the requirements used to manage charcoal quality came from the steel or chemical industries. Purchasers typically adopt these industrial quality criteria when charcoal is exported, even if the primary market for imported charcoal is the domestic cooking or barbeque market. This element should be considered since industrial and household requirements are different. An educated assessment of real market quality requirements may allow delivery of adequate charcoal at a cheaper price or in higher quantities, which is advantageous to both customer and the seller.

Moisture Level

Fresh charcoal from an open kiln contains extremely little moisture, often less than 1%. The absorption of moisture from the humidity of the air itself is quick, and there is a gain of moisture over time that, even in well-burned charcoal, can raise the moisture content to roughly 5 to 10%. When charcoal is not adequately burnt or pyroligneous acids and soluble tars are washed back onto the charcoal by rain, as might occur in pit and mound burning, the hygroscopicity of the charcoal increases and the natural or equilibrium moisture content of the charcoal can climb to 15% or more.

Moisture is an adulterant that reduces charcoal's calorific (heating) value. When selling charcoal by weight, dishonest sellers frequently wet the charcoal to keep the moisture level high. Water has little effect on the volume and appearance of charcoal. As a result, bulk purchasers of charcoal prefer to buy by gross volumes, such as cubic metres, or by weight and estimate the moisture content through laboratory testing before adjusting the price to compensate. Little marketplaces frequently sell by the piece.

How Does Charcoal Burn?

Charcoal combines with oxygen in the air at a brilliant red heat to generate colourless carbon monoxide gas, which then burns with additional oxygen to make carbon dioxide gas. Because of the heat released by both of these processes, the charcoal glows red and radiates heat energy, and the hot carbon dioxide gas exits the combustion zone, ideally giving up most of its heat by convection through direct physical contact with the cooking pot. When it transmits heat, the temperature of the gas declines, and it escapes into the room. Flues are seldom utilised with charcoal since their burning is odourless and smokeless compared to wood or coal. Charcoal combustion can produce unburned carbon monoxide gas. Charcoal is extremely hazardous, and ventilation is required in places where charcoal is being burned.

One of the essential characteristics of charcoal is its ability to be burnt in a tiny portable stove without the need for a chimney, which explains its great appeal, particularly in cities and built-up regions. Even if it is more energy efficient in the long run for a country to utilise genuine wood burnt effectively for cooking rather than first converting it to charcoal, such a strategy is difficult to execute. Changing from charcoal to wood is tough for most people right now. A wood stove with a vent is expensive. The rammed earth stove may be free, but a metal flue may be costly. Installing flues may be hard for individuals living in confined city quarters. Thus, the pollution-free characteristics of charcoal fuel are appealing in these instances.
