Which component is a steel beam attached to the furnace wall to accommodate a boiler's horizontal expansion?

Explanation:
When a boiler heats up, it expands and the structure must be braced to handle that movement without distorting. Buckstays are steel beams attached to the furnace wall that take the horizontal thrust from this expansion, anchoring the moving boiler shell to a fixed point and preventing outward bowing. That specific role—resisting horizontal expansion and keeping the furnace aligned—is what makes buckstays the right choice. Hangers, on the other hand, are for suspending components; tie rods hold parts together under tension; lintels span openings. None of those are primarily about accommodating horizontal expansion in the boiler shell the way buckstays are.
