Powder fuel oxidation method for melting furnace - delivers three air currents downwards round hollow current of oxygen

The oxidation method uses combustion gas, so that part of this is delivered in a turbulent state into the reaction chamber. To increase the working range of the furnace, two gases are used as combustion gas. The first, typically oxygen, is delivered as a separate, hollow, and partly turbulent curren...

Beschreibung
Zusammenfassung:	The oxidation method uses combustion gas, so that part of this is delivered in a turbulent state into the reaction chamber. To increase the working range of the furnace, two gases are used as combustion gas. The first, typically oxygen, is delivered as a separate, hollow, and partly turbulent current from the centre (15) of the burner (1). The second gas, eg air, is delivered in three or more separate currents (8, 13) downwards round the oxygen current. The angle between these currents is 15 to 20 deg. ADVANTAGE - Good mixing of fuel and gas.
