  • Water Tube Boilers

    The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5). Cooler feedwater is fed into a drum, which is placed longitudinally above the heat source. The cooler water falls down a rear circulation header into several inclined heated tubes.

  • CHAPTER TWO: Boiler Operation Maintenance & Safety Study Guide

    Water-tube boilers have water running through the tubes and fire or gases of combustion surrounding the tubes. The water tubes are connected into a steam drum at the top and a mud drum at the bottom. The fire is in the Combustion chamber. The boiler design can also be identified by the shape of the tube configuration, with the common types being called A, O, and D style boilers. The cast iron sectional boiler is neither fire tube nor water tube though it has some operating characteristics of a water tube boiler. The water is inside the sections and the fire is outside the sections. Cast iron sectionals used for steam heating may have distinct operating problems that are not typically found in other boiler types, such as the intolerance for poor water chemistry. • A boiler may be classified as either a steam boiler or hot water boiler.
