Coal Fuel Handling Project
Trifield Electrical Engineering delivered a hazardous area project including a coal transport and grinding system with an innovative burner management system to heat coal to a desired temperature for a major cement and lime manufacturer in Western Australia.
In 2006, the manufacturer’s gas supplier revised gas consumption sales, meaning the manufacturer would lose 25 per cent of its gas intake into the plant. There are two lime kilns and three cement kilns operating 24 hours. Lime kiln No 6 had no capacity in heating with coal and gas mixture, so the pressure was on for the lime and cement manufacturer to design and construct an alternative source of fuel to heat the existing lime kiln No 6.
The losses would be great. Management would not have this plant turned off, so a dead line date was provided which was 31st December 2007. Trifield was awarded the job, as the client had confidence in Trifield to deliver. The company was directed additional work to be completed at the same time.
The coal plant has equipment based on the latest technology with smart instrumentation and digital control throughout. Yokogawa was chosen by Adelaide Brighton for all field instruments. The coal handling plant comprises over 60 instrumentation loops with 4-20ma loop control. Production equipment installed included: two coal transport conveyors; radar level monitoring by Endress & Hauser; coal belt feed drive; triple gate valves; coal grinding and milling; burner management system; and more.
