**Glossary:** - Air: a mixture of gases containing free oxygen and able to promote or support combustion - Primary air: air supplied to the burning fuel in order to liberate combustible gases - Secondary air: air supplied to the combustible gases liberated by the primary air in order to complete their combustion. The expression "secondary air" covers "tertiary air" etc. - Burner: a device by which fluid fuel or solid fuel suspende in air is passed to a combustion space where it burns to produce a self-supporting flame. A burner includes means for feeding air that are arranged in immediate connection with a fuel feeding conduit, for example concentric with it. - Combustion: the direct combination of oxygen gas, e.g. in air, and a burnable substance - Combustion chamber: a chamber in which fuel is burned to establish a self-supporting fire or flame and which surrounds that fire or flame - Combustion zone: the part of a combustion apparatus where the reaction takes place between air and fuel - Fuel: any combustible material that can be burned, regardless of whether the main purpose of burning it is for releasing energy therefrom or for disposing of it or rendering it less harmful - Waste: an undesired material that can be consumed by combustion for the primary purpose of disposing of it or rendering it less harmful, and not solely for releasing energy therefrom
