Principle of three-burner combustion system

Principle of three-burner combustion system:

The efficient combustion comes from the periodic alternation of the three burners, so that the flue gas is used to heat the air and obtain the high-temperature combustion air. When one burner burns, the flue gas passes through the other two, heating the heat storage medium therein. When the regenerative medium is heated, the burner begins to burn, and the burner begins to smoke and discharge smoke. Combustion air

is heated when it passes through a high temperature storage medium. The air preheating temperature of combustion which is flue gas temperature should be reached not higher than 300 ° F (149 ° C), hence the extremely high heating efficiency.
