A vertical fire-tube boiler or vertical multitubular boiler is a vertical boiler where the heating surface is composed of multiple small fire-tubes, arranged vertically. These boilers were not common, owing to drawbacks with excessive wear in service. The more common form of vertical boiler, which was very similar in external appearance, instead used a single flue and water-filled cross-tubes. Another form used horizontal fire-tubes, even where this added complexity, such as the Cochran boiler.Learn More
Water-tube boiler - Wikipedia. Vertical Tubeless Boilers are fitted with Grundfos pumps as standard. Safety valve will have stainless steel trim. Gas Burner will be fitted with an air to gas ratio controller. Pressure controller is via a Siemens RWF controller, this pluses the air damper to either increase or decrease the air and gas to the boiler.Learn More
