Question

Out of the given option choose the advantage that supports fire tube boilers?

(a) Water circulation is cyclic

(b) Used as a mobile boiler

(c) Water circulation is limited inside boiler shell

(d) Bursting of flue tube does not cause any explosion

This question was addressed to me in an interview for internship.

My enquiry is from Boiler Classification topic in portion Steam Generators & Accessories of Energy Engineering

Answer 1

Right answer is (c) Water circulation is limited inside boiler shell

To explain: Water circulation is limited inside the boiler shell. Water need not be that much pure and needs minimum treatment like passing through a pressure filter. Cleaning and repairing is not easy due to inaccessible parts, furnace cannot be altered and is used for one fuel only.
