The boiler's job is to apply heat to water to create steam. There are two approaches: fire tube and water tube. A fire-tube boiler was more common in the 1800s. It consists of a tank of water perforated with pipes. The hot gases from a coal or wood fire run through the pipes to heat the water in the tank, as shown here:
Procedures for Boiler Tube Failure Analysis At times, the cause of a failure cannot be readily determined, making it difficult to determine the appropriate corrective action. A detailed examination of the failure and associated operating data is usually helpful in identifying the mechanism of failure so that corrective action may be taken.
Fire tube boilers may be operated at 135 to 150% of the rated capacity and water tube boilers may be operated at 150 to 200% of capacity. Operation of the boiler depends upon proper maintenance of
This type of boiler is a horizontal fire tube. The hot gases run through pipes that are surrounded by water. The sheets at the end of the boiler are held in place by long bolts that run through the whole boiler from one end to the other. The tubes are roll fitted into the sheets to make them water tight.

Package boilers are generally of a shell type internally fired furnace with fire tube design so as to achieve high heat transfer rates from both radiation heating surface and convection heating surface. Package type fire tube and water tube boilers are shown in pictures.
Boiler explosions can result from a number of factors. The primary reason for them is a faulty pressure relief valve.Inner corrosion of the boiler plates is another primary reason a boiler will explode or suffer a catastrophic failure. Low water levels are responsible for many instances of boiler explosion and can happen when the water falls below the level of the firebox, causing it to
Types of Superheater Boiler - Superheater is a subcritical boiler component that serves to heat the saturated steam, at constant working pressure, so it becomes superheated steam. In its development since the beginning of the 20th century, along with various boiler design races, some engineering experts patented the design of different superheater.
I started a fire of dry white pine, then i began filling it with water. Rough estimate, it probably holds a little over 100 gallons. There was a pretty good fire in there by the time the garden hose filled it up. Keep in mind, the boiler is not connected to any circulating pump at this time.
Cleaning boilers on Rosie; 1963-65. I always thought that water boiled at 212 degrees Fahrenheit at sea level; end of story. Well, I thought that way until I sat through 16 weeks of Shipboard Engineering at OCS and learned that applying lots of pressure in a Naval boiler is exactly how that temperature is raised another 300 degrees or so.
