The combustion of fluid fuel, typically fuel oil in burners or boilers is improved by applying a magnetic field to the fuel at the point upstream of the burner to impart a magnetic flux density of at least 10 gauss to the fuel, and adjusting the magnetic field to reduce to a minimum the dust and residual oxygen contents in an exhaust gas. A magnetizing apparatus is also disclosed which comprises permanent magnets and movable yokes for adjusting a magnetic flux density traversing a pipe for feeding fuel. The magnetizing apparatus is located on the pipe between pumping means and the burner.
