Paper mill pulps costs
November 1st 2007 A paper mill has installed Fuel+ technology from Maxsys saving 6.8% off its energy bill. Steam generation is an intensive process deployed by Union Papertech to dry the paper as part of its manufacture before it is dried. The mill houses a Maxecon twin-shell steam raising boiler fitted with two Saacke burners. The unit consumes 18 million kWh of gas per annum. It was agreed by Union papertech and Maxsys that ABB Engineering Services would undertake an independent evaluation of the performance of the Fuel+ systems pre and post installation using the CUDSUM statistical model. Units were fitted to each burner. Working with Union Papertech, ABB assessed the installed metering and monitoring on the boiler and produced a test protocol that outlined the performance characteristics of the plant and detailed a list of variables that would be recorded in order for ABB to monitor the boiler accurately. The test protocol was agreed and signed by ABB, Union Papertech and Maxsys. Analysis showed that gas consumption was 6.8% lower at the end of the post installation period for an identical amount of steam generated, equating to a substantial gas saving of 8229ft3 per day (equal to three million ft3 per day) with a commensurate reduction in carbon dioxide emissions. "I can't be anything else but pleased with the benefits offered by the technology," says Steve Sherlock, chief engineer. More articles from Maxsys Ltd: |
