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.

Lancashire Boiler : Principle, Construction & Working

Lancashire is a horizontal, stationary fire tube boiler. This boiler is invented by Sir William Fairbairn in the year 1844.The flue gases flows through the fire tube, situated inside the boiler shell, so it is a fire tube boiler. This boiler generatenlow pressure steam. It a internally fired boiler because the furnace is placed inside the boiler.

Finding the Root Cause of Boiler Tube Failures

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water
