COC COAL GRINDING PLANT PHILIPPINES - NORZAGARAY
Grinding capacity: 22 tons/hour.
At the end of 1999, COC contacted PEG for the turnkey installation of a coal grinding plant to decrease the fuel cost of their 3300 t/d kiln line. In March 2000, a contract was signed including a complete coal grinding plant with civil works, equipment supply and local fabrication, installation of mechanical, electrical and control equipment. The plant has been commissioned in the beginning of 2001. DETAILS: The project includes coal storage hall, transport to raw coal bins, vertical roller mill, dedusting filters, pulverized storage bins as well as delocalized intermediate bins for kiln and pre-calciner with latest coal dosing equipment kiln and pre-calciner burner. Kiln air is used for coal drying. The air after the kiln exhaust fan is dedusted by low-pressure loss cyclones and transported by means of a booster fan to the coal mill. Well-known German equipment is used for coal dosing, pneumatic transport, gas transport as well as for electrical equipment and for the control system. Other equipment such as coal storage hall and vertical roller mill is to be dismantled in another plant, owned by the client, and reinstalled on the new site. Structures, plate work and equipment parts are fabricated as far as possible locally based on PEG or sub-contractor drawings. PEG's subsidiary office, CME in the Philippines, performed the local fabrication quality control as well as erection and commissioning assistance. Civil, mechanical and electrical detail engineering was divided between PEG and CME in order to reduce the total implementation time.
