What is Smoke Chamber?

Corbelled brickwork narrowing from the firebox throat to the flue. It should present a smooth, evenly angled surface; what is often found is raw stepped brick with open joints, which produces both turbulence and a deposit trap at the coolest point in the path. It is only found by looking above the damper, which is why it appears on internal inspections and not visual ones.
