Regenerative heat sensor reservoir for combustion burner

摘要

In a regenerator made of materials each comprising alumina as a main ingredient, and used for the regenerative combustion burner which is fired with alternately and repeatedly operations of heat storage by the passage of high-temperature flue gas in a fixed time and heating of combustion air by passage of the combustion air in a next fixed time, under the condition that the flue gas includes metal dust; the alumina purities in the materials for the regenerator are lowered in the order, the high-temperature, medium-temperature and low-temperature parts of the regenerator.
