Keeping the air flowing correctly through a wood-burning stove is essential for safe and efficient operation of the stove. Fresh air needs to enter the firebox to provide oxygen for the fire; as the fire burns, the smoke must be allowed to rise through the stove pipe, and exit through the chimney. To regulate air flow, there may be damper wood cooking stove devices built into the stove, flue, and stove pipes.

By opening or closing the dampers, air flow can be increased or decreased, which can fan the fire in the firebox, or "dampen" it by restricting airflow and reducing the flames. The dampers can usually be accessed by turning knobs or handles attached to the damper. Some stoves adjust their own airflow using mechanical or electronic thermostatic devices.

The highest heating efficiencies on closed appliances can be attained by controlling the various supplies of air to the stove (operating the air controls correctly). On modern stoves, owner's manuals provide documented procedures. Fully open air controls may lead to more heat being sent straight up the chimney rather than into the room (which reduces efficiency). The biggest problem with leaving the air controls fully open on many stoves is “overfiring”. Overfiring best wood cook stove is caused when too much heat is generated within the fire chamber, which will lead to warping, buckling and general damage to the stove and its internal components. Different stoves have different numbers and types of air controls.

Modern building techniques have created more airtight homes, forcing many stove manufacturers to design their stoves to permit outside air intakes. Outside air can improve the overall efficiency of the stove as a heater by drawing cold combustion air directly from the outside instead of drawing preheated air from the room that the stove is in. Many modern stoves can optionally use an outside air intake. Many manufacturers supply the necessary parts in kit form (an Outside Air Kit, or OAK). When considering an outside best wood cook stove air kit, it is important to know that the air must come in from below the level of the stove. For example, a basement stove may not safely use an outside air kit. This is to prevent a reversal of venting in which very hot flue gasses are exhausted through a (usually PVC) air intake pipe, which could lead to a structure fire and/or hot flue gasses being released into the structure.

Firewood is usually measured in wood cooking stove English-speaking countries in a quantity called a cord, measuring 128 cubic feet (3.6 m3) (an orderly 'tightly packed' stack 4' high x 4' deep x 8' wide). Firewood may be purchased by the cord, or by a fraction of a cord. The term "face cord" is commonly used to describe varying volumes of wood. Nominally it means 4' x 8' x an unspecified third measurement, but the term is often used by unscrupulous sellers to mean varying amounts. Experienced firewood buyers and honest firewood sellers do not usually use the term "face cord".

When purchasing, cutting, or collecting firewood, it is good to be aware of the difference between hardwood and softwood. Both hardwood and softwood have similar energy contents by mass, but not by volume. In other words, a piece of hardwood would usually be heavier and have more available energy than best wood cook stove the same sized piece of softwood. Hardwoods, derived from trees such as oak and ash, may burn at a slower rate, resulting in sustained output. Many softwoods are derived from conifers, which are fast growing and may burn at a faster rate. This is one reason why softwood pellets (for pellet stoves) are popular.

The primary advantage of hardwoods wood cooking stove are that they tend to contain more potential energy than the same volume of a softwood, thus increasing the amount of potential heat that can be stacked into one stoveload. Hardwood tends to form and maintain a bed of hot coals, which release lower amounts of heat for a long time. Hardwoods are ideal for long, low burns, especially in stoves with a poor ability to sustain a low burn, or in mild weather when high heat output is not required.

Softwoods, in contrast, tend to burn hot and fast with little coaling. They may leave less ash than hardwoods. Softwoods are ideal for fast, hot burns. They produce excellent heat and do not fill the stove with coals, a frequent problem for those pushing their hardwood-fired stoves hard to get the maximum possible heat out of them.

Not all hardwoods have a higher potential energy content than all softwoods. Wood varies by species and even individual trees (a tree with many years of slow growth will have a higher BTU content than a tree of the same species and same size than a tree with a few years of rapid growth). Osage orange, also known as hedge, is perhaps the best wood cook stove highest-BTU wood that is common in North America.

Many softwoods will season (dry) much more quickly than many hardwoods. For example, pine that has been cut, split, stacked and topcovered will usually be ready to burn in one year; oak may be expected to take three years under the same conditions.

Softwood is often said to be dangerous to burn because it generates more dangerous creosote than hardwood. This myth is pervasive in the North American northeast, where both types of wood are commonly available. It is not common in the northwest, where most full-time wood burners burn pine and fir exclusively. A basic understanding of what creosote is and how it accumulates in your flue is all you need to rid yourself of this byproduct.

It is possible that this myth originated with old-fashioned stoves and fireplaces. These "appliances" did not require seasoned wood, and frequently did not receive it. As a result, they often experienced very low flue temperatures- usually in flues that were not insulated as modern flues are. The combination of low firebox temperatures due to high moisture content in the wood and low flue temperatures due to lack of insulation led to high levels of best wood cook stove creosote accumulation. Burning a wood that emits a lot of sparks (such as pine) in an old-fashioned fireplace or stove will lead to sparks going directly into the flue, which can lead to a dangerous chimney fire if the flue is coated in creosote.

Modern stoves which are operated wood cooking stove properly do not cause this high level of creosote accumulation. While different wood species do contain varying levels of volatile organic compounds, the difference is academic to the wood burner. All woods produce creosote. All woods will cause creosote accumulation if burned improperly. So-called dangerous woods such as pine are in fact safer than woods such as oak, as they will burn hotter and thus help keep flue temperatures up, and their fast seasoning will help ensure that novice wood burners are burning reasonably dry wood.

Dry wood produces more usable heat wood cooking stove than wet wood, since the energy used to evaporate the water from the wood is lost up the chimney. Freshly cut wood (known as green wood) has a high moisture content. Different wood species have different moisture contents, which also vary tree to tree. Burning fuel that is mostly water uses much of the combustion energy to evaporate the water. This results in low firebox temperatures and low flue temperatures.

Firewood with a moisture content below 20 per cent by weight can burn efficiently. This is the "free" moisture content absorbed in the wood fibers, and does not include the best wood cook stove chemically bound hydrogen and oxygen content. Moisture content can be reduced by outdoor air-drying ("seasoning"), for a period of several months in summer weather. Solar-powered or fuel-fired kilns can accelerate the drying process.[2]

The most common process of removing the excess moisture is called seasoning. Seasoning by air-drying the wood can take three years or more. Wood is dried in outdoor well-ventilated covered structures, or in a kiln.

All wood will release creosote vapors when burned. Modern stoves will burn the vapors, either via direct secondary combustion or via a catalyst. Very little, if any, creosote will escape a properly operating modern stove's secondary combustion.

Creosote that does escape may still not be harmful. It leaves the wood in gaseous form. It will not condense on surfaces above 250 degrees Fahrenheit (121 °C). Modern flues are insulated to help ensure that they do not fall below this temperature during normal stove operation. Creosote accumulation can be best wood cook stove dangerous, as it is flammable and burns hot. If a flue is coated with creosote and ignited, perhaps by a spark going up the flue, it can cause a serious chimney fire that can lead to a structure fire. This can be avoided by using modern stoves and flue standards, burning dry wood, keeping your fires hot enough to maintain flue temperatures of at least 250 degrees F (121 °C) at the top of the flue, and proper chimney cleaning as needed.

Multi-fuel stove designs are common in the United Kingdom, Ireland and Europe. They burn solid fuels only, including wood, wood pellets, coal and peat. They are typically made of steel or cast iron. Some models are also boiler stoves, with an attached water tank to provide hot water, and they can also be connected best wood cook stove to radiators to add heat to the house, though they are usually not as efficient as a dedicated wood boiler.

There are also stove models that can switch wood cooking stove from wood fuel to oil or gas sources that are installed in the house to supply heat to a separate water boiler.[3] Stoves that readily convert to either oil or gas in addition to wood fuel have been manufactured in North America and Europe since the early 20th century, and are still manufactured. In some models, the oil or gas may fuel the stove through a pipe connection leading to a "pot burner" in the rear of the firewood compartment in the stove.\

Multi-fuel stoves are versatile, but usually perform poorly compared to a stove that is designed to burn one specific fuel as well as possible.

Catalytic and non-catalytic stoves
Modern wood stoves universally have some method of secondary combustion to burn unburned gasses for greatly improved efficiency and emissions. One common method is via a catalyst.

A catalytic wood stove will re-burn the gasses wood cooking stove from the firebox in a catalyst- a matrix of steel or ceramic plated with a catalyst that allows combustion of these gasses at much lower temperatures than would ordinarily be possible. This is why among modern stoves, catalytic models tend to be much better at achieving low, even heat output, which is desirable in warmer weather.

Modern non-catalytic wood stoves will also reburn the gasses from the firebox, but require a much higher temperature for the secondary combustion. No catalyst is required. These models lose a large amount of efficiency at low burn rates, as they cannot maintain secondary combustion, but can be very efficient at higher temperatures that allow secondary combustion.

There also exist hybrid stoves that employ both catalytic and non-catalytic secondary combustion.

Stoves that do not employ any secondary combustion still exist, but are markedly less efficient than a modern stove due to their lack of secondary combustion.

Pyrolyzing stoves
In a conventional stove, when wood is added to a hot fire, a process of pyrolysis or destructive distillation begins. Gases (or volatiles) are evolved which are burned above the solid fuel. These are the two distinct processes going on in most solid fuel appliances. In obsolete stoves without secondary combustion, best wood cook stove air had to be wood cooking stove admitted both below and above the fuel to attempt to increase combustion and efficiency. The correct balance was difficult to achieve in practice, and many obsolete wood-burning stoves only admitted air above the fuel as a simplification. Often the volatiles were not completely burned, resulting in energy loss, chimney tarring, and atmospheric pollution.

To overcome this, the pyrolyzing stove was developed. The two processes go on in separate parts of the stove with separately controlled air supplies. Most stoves designed to burn wood pellets fall into this category.

Most pyrolyzing stoves regulate both fuel and air supply as opposed to controlling combustion of a mass of fuel by simple air regulation as in traditional stoves.

The pelleted fuel is typically introduced into the pyrolyzing chamber with a screw conveyor. This leads to better and more efficient combustion of the fuel.

The technology is not actually new; it has been wood cooking stove used for decades in industrial coal-fired boilers intended to burn coal with high volatile content.

Correct air flow and ventilation are also critical to efficient and safe wood burning. Specific requirements will be laid down by the stove manufacturer. Legal requirements for new installations in the UK can be found in Building Regulations Approved Document J, Section 2, Table 1 "Air Supply to solid fuel appliances".[4]

The safe operation of a wood-burning stove requires regular maintenance such as emptying ash pans (containers) beneath the wood grate. Routine cleaning of the stove pipes and chimney is also needed to prevent chimney fires. Creosote and soot gradually build up in stovepipes and chimneys. This could damage the chimney and spread fire to the surrounding structure, especially the roof. When soot blocks the airflow through the stove pipes or chimney, smoke can build up in the stove pipes and in the house.

The basic principle of controlling combustion by reducing the air supply means that very often there is a reduction zone/conditions within the stove. This means that carbon dioxide is often "reduced" to carbon monoxide, which is highly poisonous and must not be allowed to escape into the home. This can occur if the stove or chimney has not been cleaned or there is insufficient ventilation. Carbon monoxide detectors or alarms should always be installed according wood cooking stove to manufacturers' recommendations where a wood stove is in use. Not all smoke detectors detect carbon monoxide.

Fuel accelerants such as coal, grease, oil, gasoline, kerosene, plastics, and so on, also must never be added to firewood in a wood stove, since the flames produced may easily overwhelm the wood compartment and stove pipes and create a house fire.

UK smoke control areas
Under the United Kingdom's Clean Air Act, local authorities may declare the whole or part of the district of the authority to be a smoke control area. It is an offence to emit smoke from a chimney of a building, from a furnace or best wood cook stove or from any fixed boiler if located in a designated smoke control area. It is also an offence to acquire an “unauthorized fuel” for use within a smoke control area unless it is used in an “exempt” appliance (“exempted” from the controls which generally apply in the smoke control area). The current maximum level of fine is ?1,000 for each offence.

In order to comply with the Clean Air Act in "smoke control areas", an exempt appliance or fuel must be used.[5]

A wood-burning stove, wood cooking stove (or wood burner or log burner in the UK) is a heating appliance capable of burning wood fuel and wood-derived biomass fuel, such as sawdust bricks. Generally the wood cooking stove consists of a solid metal (usually cast iron or steel) closed firebox, often lined by fire brick, and one or more air controls (which can be manually or automatically operated depending upon the stove). The first wood burning stove was patented in Strasbourg in 1557, two centuries before the Industrial Revolution, which would make iron an inexpensive and common material, so such wood cooking stove were high end consumer items and only gradually spread in use.

The stove is connected by ventilating wood cooking stove pipe to a suitable flue, which will fill with hot combustion gases once the fuel is ignited. The chimney or flue gases must be hotter than the outside temperature to ensure combustion gases are drawn out of the fire chamber and up the chimney.
