Wood briquettes represent the most widely used alternative fuel in Europe today. In the United States, however, the public has not become accustomed to them and their use is limited to a few rural areas. The burning of dkbrænde and the resulting ash pose many hazards that must be addressed before the public becomes comfortable with the clean burning alternative.
Wood briquettes, also known as wood ash, are a compressed form of wood derived from dead, compacted wood, typically from the heartwood of large trees. They are usually manufactured from unprocessed or recycled wood waste or byproduct and machine-compressed to a block or log form, generally without any added ingredients, although they may contain variously-sourced ingredients such as peat, sawdust, or newspaper. They are an effective source of firewood, providing a clean burning fuel with little smoke or ash. Their compressed state allows for an economical means of storage and transportation, and they are available to most users.
There are two primary types of wood briquettes, single cavity and double cavity. The first type functions by allowing the same amount of air flow through a closed channel, but is much more efficient at doing so. As a result, the product maintains a constant temperature, while simultaneously generating greater amounts of heat. A double cavity type heats the fuel through combustion, creating a very effective source of supplemental heat. Both types of wood briquettes, however, have limitations to their effectiveness. Double cavity wood briquettes are more difficult to ignite and burn and require additional fuel sources to generate their full heat output.
When selecting quality wood briquettes for your home heating system, it is important that you select the appropriate type for your intended use. For example, some manufacturers make briquettes that are suited for stovetop applications, but which is inefficient as a heating source for home patio cooking. If you use a fireplace or patio space to prepare food, you will likely want to use smaller wood briquettes. On the other hand, a wood stove can benefit from larger pieces of wood that produce more heat and which can be stacked in single units to provide greater efficiency.
One thing to keep in mind when purchasing a wood briquette for your home heating system is that there are some briquettes that burn more efficiently than others. These products are usually known as “high quality” briquettes and come with the additional benefit of being more durable and offering a clean burn with fewer ashes. However, keep in mind that purchasing a high quality briquette will require more expensive fuel sources and will also burn cleaner.
In general, the best quality briquettes burn cleanly and produce a clean burn. The burn is more consistent with these types of products, and the cost of using these products typically is a few cents per pound. Since most home fires begin with a spark or flame, using the best quality briquettes will prevent damage to your home and increase the efficiency with which they are used. Wood is a great choice for stoves because it contains moisture, and burning wood produces plenty of that moisture, which keeps the fire going, even when your masonry chimney is at full capacity.
