Roaster analysis Afterburner system for coffee roasters
Afterburner system, also known as direct-fired thermal oxidizer system. Direct-fired thermal oxidizer or post-burner is the simplest thermal oxidizer, which uses a high temperature of about 500 degrees to instantly ignite soot or carbonized ions into clean water vapor, which can greatly reduce VOC emissions. This thermal oxidizer does not have any heat recovery equipment and cannot recover the heat generated during combustion. typical
