Identify the incorrect statement regarding the efficiency and operation of different types of boilers.
1
High-pressure boilers are more efficient than low-pressure boilers due to better heat transfer and higher operating pressures.
2
In water tube boilers, the risk of explosion is higher than in fire tube boilers due to the high pressure and temperature of the water inside the tubes
3
Fire tube boilers are generally more suitable for high capacity and high-pressure applications compared to water tube boilers.
4
Babcock and Wilcox boiler is suitable for high pressure and high capacity applications due to its water tube design.
