• Difference between Fire Tube and Water Tube Boiler

    The main difference between Fire Tube and Water Tube Boiler is that In Fire Tube Boiler, hot flue gases pass through tubes and water surrounds them, and In Water, Tube Boiler water passes through tubes and hot flue gasses is surround them. These boilers mostly use in the power development industries, sugar industries, cotton industries, etc.Learn More
