Knowra Firewood Firewood Firewood is wood gathered or processed for burning as fuel, especially in fireplaces, stoves, and outdoor fires. Its suitability depends on moisture, species, size, and preparation.
Wood : A porous structural material formed by the stems and roots of trees and other woody plants. Firewood is wood selected and prepared for combustion.
Combustion : A chemical reaction in which a fuel reacts with an oxidizer, releasing heat and often light. Firewood releases energy when its combustible compounds react with oxygen.
Wood-burning stove : An enclosed appliance that burns wood to provide heat, often through a flue. Stove size and design determine the firewood length and burn conditions required.
Household air pollution : Air contamination inside or around homes from activities such as cooking and heating with solid fuels. Indoor fires and stoves can expose occupants to smoke from burning firewood.
Charcoal : A carbon-rich solid fuel made by heating organic material with limited oxygen. Unlike ordinary firewood, charcoal is processed before use and burns with different smoke and heat characteristics.
Wood species : The botanical identity of a tree species, which influences its wood's density, structure, and properties. Species affect firewood's heat output, splitting, and burning behavior.
Pyrolysis : The thermal decomposition of material in the absence of sufficient oxygen for complete combustion. Heating wood first breaks it into gases, vapors, and charcoal that feed the fire.
Fireplace : A built-in or freestanding structure that contains a fire and directs smoke into a chimney or flue. Fireplaces use firewood for heat, cooking, or atmosphere, with efficiency shaped by their design.
Particulate matter : A mixture of tiny solid particles and liquid droplets suspended in air. Wood smoke contains fine particles that can enter the lungs.
Pellet fuel : A manufactured fuel made by compressing small particles of biomass into uniform pellets. Pellets offer consistent size and automated feeding, unlike irregular logs.
