A regenerative combustion system uses a pair of burners, each equipped with a media case filled with dense ceramic material. These burners alternately switch between firing and exhausting modes. During exhaust mode, hot combustion gases pass through the ceramic media, storing heat close to furnace temperature.
When the burner switches to firing mode, cold combustion air flows through the heated ceramic media, rapidly increasing air temperature before combustion. This cyclic operation captures and reuses waste heat from flue gases, resulting in exceptional fuel efficiency for high-temperature industrial processes.
