1.2The chamber in a steam engine or boiler between the flues and the funnel or chimney stack.
- On 610-614 the combustion chamber ahead of the smokebox was made a foot longer; the tubes and flues, thus reduced a foot in length, were, at 20 feet long, precisely the length needed for best absorption of heat.
- Operation probably isn't possible without a whole new boiler, and the holey smokebox will need heavy patching even if it doesn't get one.
- Slipping at starting was rare, however, due to a very careful design of regulator valve in the smokebox; very small adjustments could be achieved, and any slip could be quickly checked.
1.3 another term for smoker (sense 4).
