Title: Control of combustibility of volatile hydrocarbons and particulate matter in an exhaust gas stream by use of a high velocity burner in a carbon bake ring furnace

Patent ·
OSTI ID:6063708

The present invention relates to a method of and an apparatus for controlling the combustibility of volatile hydrocarbons and particulate matter in an exhaust gas stream driven off from a carbon product being baked in a furnace. In a prebaking stage, the carbon product is heat treated in a temperature range of 300 to 600/sup 0/ C. In order to drive off the volat hydrocarbons and particulate matter and form the exhaust gas stream. The exhaust gas stream is heated to a temperature of at least 900/sup 0/ C. And at least one heat transfer medium is forcedrafted and mixed into the exhaust gas stream so that the stream contains at least approximately 6% oxygen. The volatile hydrocarbons and particulate matter in the exhaust gas stream are combusted into non-polluting compounds having an opacity less than 40% for exhaustion from the furnace into the outside atmosphere.
