What are five advantages and five disadvantages of a fire tube boiler?
Give this one a try later!
Advantages: Lower initial cost, Compactness, Occupies a minimum amount of
floor space, Less or no settings, Rapid response
Disadvantages: Poor circulation, Not efficient - hard to clean, Heat stress,
Capacity/pressure/steam temperature is limited.
What are tube ligaments?

Area between the tube holes on a tube sheet
Two boilers are made of the same grade of steel, same thickness of plate and same type
of joints. One is 30" diameter the other is 60" diameter. Which will withstand the greatest
