ARCH

The roof or crown constructed on a radius for different parts of the furnace.

BACK WALL (OR GABLE WALL)

The section of wall above the soldier blocks at the furnace charging end.

BATCH

The mixture of raw materials to a given composition, ready for delivery to the furnace melting end.

BATCH CHARGER

A machine that introduces the batch into the furnace melting end.

BATCH HOUSE

The building where the raw materials are delivered, stored, handled, weighed, mixed and transferred to the furnace batch storage hopper.

BRACE BOLT (OR JACK BOLT)

Steel bolts that apply pressure to the outside face of the constructed furnace refractory structures to act against internal outward pressure.

BRACING MEMBER

Steel members that brace the furnace refractory structure.

BREAST WALL

The section of sidewall between the soldier block and the crown skewback.

BUCKSTAY

The vertical structural steelwork members positioned adjacent to the outside face of the furnace refractory structures to which refractory supporting steelwork members are fixed.

BURN OUT (OR THERMAL CLEAN)

A method of cleaning out deposits blocked in the regenerator checkers (or packings) using heat.

BURNER BLOCK

A refractory block with one main aperture through which the fossil fuel burners fire.

CAMPAIGN

The working life of a tank furnace from the start of a new furnace construction to the shut-down of the furnace.

CASING

The steelwork case supporting the forehearth sub-structure refractory.

CHANNEL

The sub-structure part of the forehearth that carries the molten glass from the distributor (working end) of the furnace to the spout.

CHECKERS (OR PACKINGS)

The refractory pieces installed in the regenerator chamber for the purpose of heat recovery.

CONDITIONING ZONE

The part of the forehearth after the cooling zone(s) where the glass is brought to the required working temperature.

CONTINUOUS TANK FURNACE

A furnace which produces glass on a continuous basis in which the level of the glass remains relatively constant due to the batch being fed continuously into the furnace, therefore, replacing the glass withdrawn.

CONTROLLED COOL-DOWN

The cool-down of a furnace from working temperature to ambient temperature under controlled conditions.

COOLING ZONE

The part of a forehearth adjacent to the refiner (or distributor/working end) and before the conditioning zone.

CROSS-FIRED FURNACE

A tank furnace with parallel pairs of ports for fuel and air positioned along the length of the melting end with the burner flames travelling across the width of the glass bath and at right angles to the direction of glass flow.
