Operation of a combustion control system of furnace is controlled by image analysis, outside of the furnace or within the furnace, of a flame produced by combustion within the furnace, to correlate the image with carbon monoxide content of the flame, and adjustment of the oxygen and/or fuel flow into the furnace in response to the correlation.

Flame image analysis for furnace combustion control

A method and system for method for removing solid accretions from a copper anode or holding furnace using coherent jet lance assembly directed towards the solid accretions in the bottom portion of the copper anode furnace to melt the solid accretions over an extended period of time without damage to the furnace refractory proximate a point of stream impingement.

Method and system of removing accretion buildup in a furnace

A method and system for the copper anode refining is provided in which coherent jet technology is employed to heat the molten blister copper and/or melt scrap copper charges using a melting flame, oxidize the sulfur in the molten blister copper, and reduce the oxygen in the molten blister copper using top-blown coherent jet gas streams from one or more multi-functional, coherent jet lance assemblies. The present system and method employs a microprocessor-based controller operatively controlling the flow of an oxygen-containing gas, an inert gas, a reducing agent and a fuel to the coherent jet lance. The disclosed copper anode refining system and method greatly improves copper production while lowering oxidation/reduction cycle times and minimizing NOemissions.
