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 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.
Only propane produced specifically for use in refrigeration systems – with a purity of at least 98.5% and moisture content below 10ppm (by weight) – should be used. [1] With a global warming potential (GWP) of 0.072 [2] and an ozone depletion potential (ODP) of 0, R-290 is of very little threat to the environment.
The enthalpy of combustion of propane gas where products do not return to standard state, for example where the hot gases including water vapor exit a chimney, (known as lower heating value) is −2043.455 kJ/mol. [29] The lower heat value is the amount of heat available from burning the substance where the combustion products are vented to the ...
In 1987 the US Department of Agriculture published a method for producing kiln dried firewood, on the basis that better heat output and increased combustion efficiency can be achieved with logs containing lower moisture content. [4] The magazine "Wood Burning Quarterly" was published for several years before changing its name to "Home Energy ...

Wood gas is a fuel gas that can be used for furnaces, stoves, and vehicles. During the production process, biomass or related carbon-containing materials are gasified within the oxygen-limited environment of a wood gas generator to produce a combustible mixture.
The energy content is about 4-4.2 kcal/kg and moisture content is typically less than 10%. The size of pellets is generally kept to be about 6 mm diameter and 25 mm length in the form of a cylinder; though larger cylinder or briquette forms are not uncommon. It is much cheaper than similar energy-pellets and can be compacted/manufactured from ...
Propane burner with a Bunsen flame Oxy-Acetylene for cutting through steel rails Flame of a gas and oil, in a dual burner. A gas burner is a device that produces a non-controlled flame by mixing a fuel gas such as acetylene, natural gas, or propane with an oxidizer such as the ambient air or supplied oxygen, and allowing for ignition and ...
