Definition
A watertube boiler with multiple drums connects by shaped tubes.
Circulation becomes more complex in a bent-tube boiler. Bent-tube
boilers operate at higher pressures and higher steam capacities
than straight-tube boilers. Common bent-tube boiler configurations
include A, D, and O styles.
