2019-10-21 · 1. Tubes in horizontal fire-tube boilers deteriorate more rapidly at the ends toward the fire, and they should be carefully tapped with a light hammer on their outer surface to ascertain whether there has been serious reduction in thickness. 2. The tubes of vertical tubular boilers are more susceptible to deterioration at the upper ends
The boilers are normally mounted vertically and generally have three tube passes with between 300 and 800 tubes inside the boiler, ranging from hot in the center to cold in the outer parts. On-line cleaning of smoke tube boilers is challenging and must be combined with manual cleaning as well.

2020-2-13 · Boiler preservation is necessary beacuse if we do not preserve any boiler during short term or long term shutdown/ stoppage, then chances of water side corrosion which lead to scaling amp; finally tube failure may be occurred. There are two method of boiler preservation for during boiler shutdown :-1.Wet preservation :-
The most common fire-tube boilers used in facility heating applications are often referred to as ''scotch'' or ''scotch marine'' boilers, as this boiler type was commonly used for marine service because of its compact size (fire-box integral with boiler section). The name "fire-tube" is very descriptive.
