Why is a water tube boiler more prepared than a fire tube

Answer (1 of 2): Like another answer, I don't know what is meant by "prepared" - maybe "preferred"? Fire tube boilers were the forerunners of water tube boilers, still used in preserved locomotives, but no longer in ships. The most famous fire tube boilers were the Scotch boilers, which were pr

Thermally Induced Stress Cycling (Thermal Shock) in

Thermally induced cyclic stresses are due to the resistance of the boiler structure to movement caused by thermal expansions and contractions within the boiler. The stresses occur every firing cycle (burner on, burner off), in varying magnitudes. Failures of this type may appear as leaks at the tube-to-tubesheet joints, cracked tubesheet

The other type is a water tube steam boiler. It is just the opposite of the fire tube steam boiler; the water is in the inside of the tubes and the hot gases are on the outside of the tubes. In the fire tube boiler, we have a limitation on the combustion chamber diameter and length, and it cannot exceed a certain value.

Finding the Root Cause of Boiler Tube Failures

Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube

Roll the tube to what you estimate to be a good tube joint (by feel or an estimated torque setting) and check the ID of the tube with a tube gauge. Take caution not to over roll as it can cause damage. Subtract "F" from the rolled diameter to determine the actual amount of expansion (tube wall reduction) on the inside diameter of your tube.

The top tube sheet in a steam boiler can be above or below the water line. When it is above, it is called a dry-top and when it is below, it is called a wet-top. A vertical boiler has a small "footprint" and can be installed in boiler rooms with limited space. Vertical boilers are very popular in the dry cleaning industry.
