An intelligent sequencing system for steam boilersEngineering360 News Desk | September 08, 2020
Process steam and heat transfer specialist Fulton has launched SCOPE, a new programmable logic controller-based boiler sequencing control system that can optimize installations to ensure energy efficient operation and improve boiler longevity.
With many facilities operating multiple boilers for their processes, SCOPE is a universal control system suitable for sequencing up to four steam boilers, which can be retrofitted to existing vertical and horizontal fuel-fired boiler installations, including Fulton’s own range of existing and planned products and those manufactured by other boiler original equipment manufacturers.
The company claims the intelligent sequencing system provides redundancy and reliability benefits that translate into significant savings by automating start-up and shut-down procedures, controlling and optimizing main steam header pressure or temperature and ensuring steam supply is controlled precisely for the required process. By additionally balancing load distribution across the boilers, extensive losses from repeated start/stop cycling of burners can be eliminated.
SCOPE features a high-definition touch screen used for system programming and displaying boiler status, with values presented including firing rate, fault history and TDS value logging. SCOPE also allows remote access so service engineers can review boiler status and/or alarm conditions and control system functionality according to process demand.
Additional features include lead/lag control of up to four boilers, steam header pressure monitoring with low/high alarm warning facility, automatic changeover of banked/lag boiler in the event of a fault or increased steam demand, and automated slow-opening steam valve control to assist safe operation of boiler priority, emergency steam valve and/or boiler shutdown.
