Corrosion fatigue failure of tubes in water tube boilers
The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water circulation. Advantages of water-tube boilers: They have a small water content, and therefore respond rapidly to load change and heat input.

Why are the tubes of water tube boilers kept inclined? …
This is to encourage convection in the tubes, as heat rises. A circulation between the water drum and steam drum is set up in order to heat the water uniformly; the heated water wall is called the riser, the return (cooler) water wall is the Downc

Stirling Water-tube Boilers - ASME
Water-tube boilers were of value in low-headroom conditions to produce continuous and economical production of steam even when using poor feedwater or under sudden load swings. Babcock and Wilcox, which had introduced safety boilers in 1867, purchased the Stirling Boiler Company in 1906, initiating the mass production of B&W bent-tube boilers at Stirling's plant in Barberton, Ohio.
