The Furnace is a chamber where dilythium coal is burned in an excinerative reaction. All but one wall of the furnace is highly insulated and shielded from heat. Dilythium coal is fed into the furnace through fuel ports with insulated locks similar to an air lock. In the furnace the dilythium coal is exposed to an Ætherine gas called Retrogen, which creates the excinerative reaction as the gas breaks down the coal and releases its energy.
Controlling this reaction is the job of the ship's Firemen. These enginesmen monitor the temperatures in the coal basin with thermal imagers. They have to distribute the fuel evenly with coal bed manipulators to avoid hot spots. The firemen also control the flow of retrogen through the ætherine Injectors.
The heat in the furnace is directed to the barrier or convection plate between the furnace and the energizer. This plate is called the hyper-collindar. The hyper-collindar is a shielded barrier that can contain the excinerative reaction on one side while transducting all heat through itself and allowing it to flow into the phlogisten-invigorating medium.
The Energizer is a chamber filled with phlogisten invigorating fluid. This medium is able to transfer energy to the phlogisten charging conduits that run the length of the energizer. As depleted or discharged phlogisten feeds into the Coils it absorbs energy from the medium and is invigorated with power. When the phlogisten exits it is referred to as charged phlogisten. Pumps are responsible for controlling the flow. Phlogisten conduits wind their way through the ship. Charged phlogisten conduits are highly insulated and encased in shielding. The return conduits are only lightly protected.
The exhaust from the furnace is bled out of the chamber using nanobolic flow valves and is directed up the stacks. Just above the energizer the exhaust is forced through a venturi, which draws cyneogene vapor from the phlogisten invigorating fluid. When these two mingle they not only accelerate the ætheric decay they produce an electrogenic field, which is used to rejuvenate the Veridigen system, which will be described later.
