THERMAL OIL BOILER (FOUNDRY) – RE-BOIL 6/330

THERMAL OIL BOILER
RE-BOIL 6/330

Plant description:
Waste heat recovery system on flue gas coming from brass shavings drying line in a foundry.

The waste heat recovery system consists of N.3 heat recovery thermal oil boiler with same thermal capacity (6 MW cad.) RE-BOIL 6/330.

Each heat recovery boiler RE-BOIL 6/330 is multitubular type, consisting of radiant channels and convective tubes bundle, intermediate textile expansion joint between radiant and convetive section, equipped with boiler cleaning system (pneumatic hammer rapping system), lower hoppers for the collection of ashes and dust, instrumentation and safety devices.

Technical data RE-BOIL 6/330:
– Heat output at thermal oil: 6 MW
– Thermal oil temperature (in/out): 145/295 °C
– Boiler design pressure: 14 barg

The thermal oil flow heated up to temperature of about 300 ° C feeds two ORC (Organic Rankine Cycle) turbogenerators generating 1 MWel and 2 MWel ca.
