Suction Dredges “Duwamish” “Tualatin” Steam generated in Vertical Tubes can escape to the steamdrum by its natural buoyancy, while in horizontal tubes it can only be liberated after being forced with the water into the steamdrum. ‘Think about this important feature and understand why BALLIN BOILERS furnish dry steam. Because of Vertical Tubes BALLIN BOILERS can use smaller tubes, which means Safety, Light Weight, Ease of Repairs and Compactness. BALLIN BOILERS have a large Combustion Chamber; all Engineers know its importance. Sediment will not lodge in Vertical Tubes, for this reason the Engineers like them.
