Research Details
Constructed with aluminized steel exterior, No. 830 features 24 in. wide, 1 x
1 in. Type 304 SS flatwire conveyor belt with ¾ hp motor drive, and fixed speed
of 15 fpm. Workloads travel through 54 in. long open belt loading zone, 105 in.
long insulated heat zone with recirculated airflow, and 36 in. long open
unloading zone. Modulating gas burner produces 800,000 btu/hr, while 6,000 cfm,
5 hp recirculating blower provides vertical downward airflow to workload.
Grieve Corporation introduces No. 830, a 1200°F gas-heated belt conveyor
oven, currently in use for preheating electric motor rotors at a customer's
location.
Workloads travel atop a 24" wide, 1" x 1" Type 304 stainless steel flatwire
conveyor belt with 3/4 HP motor drive, fixed speed of 15 feet per minute,
through a 54" long open belt loading zone, 105" long insulated heat zone with
recirculated airflow and a 36" long open unloading zone.
800,000 BTU/HR are installed in a modulating gas burner, while a 6000 CFM, 5 HP
recirculating blower provides vertical downward airflow to the workload.
No. 830 features 10" thick insulated walls, comprising 2" of 1900°F block and 8"
of 10 lb./cu.ft. density rockwool insulation. This conveyor oven has an
aluminized steel exterior, Type 304, 2B finish stainless steel interior,
motor-operated vertical lift doors at each end of the heat zone and 1/4" plate
work surfaces at each end of the oven.
All safety devices required by IRI, FM and NFPA Standard 86 for gas-heated
equipment are built into this unit, including electronic flame safeguard
protection, powered forced exhauster, exhauster airflow safety switch, purge
timer, hi/lo gas pressure switches, manual reset main gas valve and testing
device for tight closure of main gas valve.
This conveyor oven was entirely designed, engineered, built and fully tested by
Grieve.
