1600°F Gas-fired Furnace

No. 875 is a gas-fired, 1600ºF (~871ºC) specialty furnace from Grieve, currently used for burning off hydrocarbons from machined alloy components at the customer’s facility.  Three workspace stations are provided in this furnace, each measuring 10” W x 10” D x 2” H.  500,000 BTU/HR are installed in a modulating natural gas burner to heat the unit.  An exhaust hood is positioned over the flue, with a remote mounted 16” dia. tubeaxial fan, driven by a 3/4 HP motor.

This unique Grieve furnace features 5” thick insulated walls throughout, comprising 2” of 2300ºF ceramic fiber and 3” of 1900ºF block insulation.  In addition, 6-1/2” floor insulation is made from 4-1/2” of 2300ºF firebrick and 2” of 1900ºF block insulation.

Three air-operated vertical lift doors seal the workspaces, while three independent timers are provided, each with a pilot light, audible alarm and safety door interlock, to individually time the process cycle in each furnace compartment.  A tower light is onboard to indicate operational status.

No. 875 is built to JIC/NEMA 12 electrical standards.
