Abstract
A method and apparatus for improving the performance of a regenerative burner has a combustion chamber which receives and combusts controllable amounts of auxiliary fuel, an oxidizing gas, and possibly air to form hot combustion products. A controllable amount of a main fuel is then delivered to the combustion chamber and is pyrolyzed by the hot combustion products to produce a hot flame. By controlling the flame, one can maintain optimal temperature of the combustion air passing through the flame. Sensing means and computing means allow for automatic adjustments of fuel, oxygen and air flow to further maintain optimal combustion air temperatures.
Claims13
A method of melting material in a regenerative furnace comprising the steps of:
- (a) directing a stream of preheated combustion air toward the interior of said furnace;
- (b) introducing controllable amounts of an auxiliary fuel into a combustion chamber;
- (c) introducing an auxiliary oxidizing gas into said combustion chamber so that said oxidizing gas mixes with said auxiliary fuel and combusts to produce hot combustion products;
- (d) directing a main fuel into said combustion chamber so that said main fuel is pyrolyzed by said hot combustion products to produce a hot luminous stream of combustible gas;
- and
- (e) directing said hot luminous stream of combustible gas from said combustion chamber to the interior of said furnace to mix with said combustion air to form a final luminous flame envelope to heat the material to be melted.
