AI Technical Summary
Technical Problem
When the temperature of the processing chamber is lower than the fuel gas self-ignition temperature, it is difficult to effectively heat the treatment chamber, affecting combustion efficiency and temperature control.
Method used
The treatment chamber is heated by guiding the combustion air through the heated regeneration bed in the preheated mode and directing the fuel-rich mixture into the processing chamber, where combustion is performed adjacent to the preheated combustion air stream.
Benefits of technology
When the temperature of the processing chamber is lower than the fuel gas self-ignition temperature, the treatment chamber is effectively heated through the preheating mode to improve combustion efficiency and temperature control accuracy.

Abstract
The present invention provides a regenerative burner system and a method for heating a process chamber of a furnace using combustion of reactants including combustion air and fuel gas. The method heats the process chamber in a preheating mode when the temperature of the process chamber is below the auto-ignition temperature of the fuel gas. The preheating mode forms preheated combustion air by directing the combustion air through a regenerative bed. The preheated combustion air stream is directed into the process chamber without being mixed with the fuel gas. The preheating mode also forms a fuel-rich mixture of the fuel gas and the unheated combustion air. The fuel-rich mixture is directed into the process chamber adjacent to the preheated combustion air stream.
