Charge Lid
The lid over a charging hole. Coking needs coal heated without air, and a hopper's open top will not do that - shut this and the crown is sealed.
The lid is the second half of sealing a chamber: coking is destructive distillation, so a chamber bakes only when both this lid and the Charge Door in front of it are shut, and it makes no difference which one is standing open, coking simply does not start either way.
Right-click to swing it. See Coke and fuel.
