Boilers - University of Alabama

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Part 3 - National Board of Boiler and Pressure Vessel

Pulling A Vacuum. When boilers are designed to operate at very high pressures, they are not designed to operate under even the slightest vacuum. A potential vacuum is created when a boiler is shut down. As the unit cools, the steam condenses and water level drops, which allows the pressure to drop.

Vacuum receivers are sometimes utilized on the lowest pressure steam in acid, copper, hardness, and others, to reach the boiler and deposit within the boiler tubes. Condensate typically contains some oxygen and, under low pH conditions (< 8.3), carbon under a vacuum has a potential to draw in air and increase corrosion. This corrosion can

Pressure gauges are connected to the steam space of the boiler and usually have a ring type siphon tube which fills with condensed steam and protects the dial mechanism from high temperatures. Pressure gauges may be fitted to other pressure containers such as blowdown vessels, and will usually have smaller dials as shown in Figure 3.7.9.
