Morphology

furnace + lining

The meaning is directly compositional: 'furnace' (heating enclosure) + 'lining' (an inner layer) yields an inner protective layer inside a furnace. The general sense of 'lining' as an internal layer is cross-linguistically common and follows a standard noun+noun pattern, so a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

Furnace lining is a simple, literal name: it means the lining, the inner layer of a furnace, like a protective coat. That inner layer keeps the furnace walls safe from very high heat, so the phrase refers to the heat-resistant material that 'protects' the furnace.
