  • Boiler Drum Structure

    Boiler Drum is the most important equipment in boiler equipment, and plays a connecting role. When water becomes qualified superheated steam in a boiler, it has to go through three processes: heating, vaporization and overheating. Heating from feed water to saturated water is a heating process. V...
