Note(s)

In this class, the following terms are used with the meanings indicated:

  1. "Combustion" means the direct combination of oxygen gas, e.g. in air, and a burnable substance. Any other heat-producing combination of chemical substances, e.g. hydrogen peroxide and methane, iron oxide and aluminium, is provided for in Section C or in sub-class F24J.
  2. "Combustion chamber" means a chamber in which fuel is burned to establish a self-supporting fire or flame and which surrounds that fire or flame.
  3. "Burner" means a device by which fluent fuel is passed to a combustion space where it burns to produce a self-supporting flame.
  4. "Air" means a mixture of gases containing free oxygen and able to promote or support combustion.
