REGENERATIVE HEAT RESERVOIR FOR COMBUSTION BURNER

摘要

A heat reservoir of a material formed mainly of aluminum for a regenerative combustion burner burning while alternately repeating a heat reservation by the passing of hot combustion exhaust gas for a specified time and a heating of combustion air by the passing of the combustion air for a next specified time, wherein, when metal dust is contained in the combustion exhaust gas, the aluminum purities at the high temperature part, medium temperature part, and low temperature part of the exhaust gas are lowered steppingly in this order.
