1.	What is the major disadvantage of the Benson boilers?(a) Boiler is big in size(b) Has large storage capacity(c) Deposition of salts(d) Bubble formationI got this question in an online interview.This interesting question is from Types of High Pressure Boilers topic in division Steam Generators & Accessories of Energy Engineering
Answer» The correct OPTION is (c) Deposition of salts To explain I WOULD say: The major DISADVANTAGE of the Benson boiler is that when water transforms into steam in the convective section of the EVAPORATOR, salts are DEPOSITED in the transformation zone. Hence periodic flashing of evaporator tubes in the convective section is necessary.
