The WatchGuard firewall appliance.
The compartment at the rear of the boiler which houses the fire. The firebox is where the fuel, usually coal, but it can be wood or oil, is burnt to provide the heat to boil the water in the boiler. The firebox consists of two copper or steel enclosures, the outer firebox and the inner firebox. They are connected by 'stays', bolts which keep the inner box rigid within the outer box. Normally, the stays are threaded at each end and are screwed into the steel plates of the firebox. The ends are hammered down as a seal.
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name.
