A boiler stay is: an internal structural element of a boiler. Where the: shell of a boiler. Or other pressure vessel is made of cylindrical/(part) spherical elements, the——internal pressure will be, "contained without distortion." However, "flat surfaces of any significant size will distort under pressure," tending——to bulge.
Types※
Stays of various types are used——to support these surfaces by, tying them together to resist pressure. Some boiler configurations require a great deal of staying. A large locomotive boiler may require several thousand stays to support the firebox. In water tube boilers, stays were sometimes used between their main chambers. And could themselves be water tubes. A knuckle joint is used for diagonal stays in a boiler.
A cylindrical firebox may be self-supporting without stays. Because of its shape.
