Grieves New Oven Burns Hydrocarbons from Machined Metal Parts
The new No. 875 oven from Grieve 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" diameter tubeaxial fan, driven by a 3/4 HP motor.
This furnace features 5" thick insulated walls throughout, comprising 2" of 2,300ºF ceramic fiber and 3" of 1,900ºF block insulation. In addition, 6-1/2" floor insulation is made from 4-1/2" of 2300ºF firebrick and 2" of 1,900ºF 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.
