Emerson Process Management has been awarded a contract to update the instrumentation and controls on units 5 and 6 of the lignite-fired Belchatow Power Plant in Poland. The project will see Emerson serving as the main automation contractor, responsible for modernising the instrumentation, control and electrical subsystems.Emerson will perform engineering and management services that include the installation of its Plantweb digital plant architecture with the Ovation expert control system. Using open Wirelesshart products, Emerson's Smart Wireless network will connect over 110 Rosemount wireless temperature transmitters that will monitor boiler temperatures on each unit. The complete retrofit project will enable the units to reach 320,000 hours of operation.
The project will contribute to emissions reductions from the two units, with CO2 and NOx both falling below 200mg/m3. Emerson will design, install and commission the digital automation system and perform various services on the units' electrical subsystems, such as the generator, transformers, feeder ducts and switchgear.
Emerson's Ovation system will monitor and control each unit's boiler and balance of plant processes and equipment, as well as the 0.4 and 6kV electrical switchgear and unit power output. In addition, it will interface with each unit's turbine control and thermal-protection systems. The Ovation system will oversee automatic boiler/unit start-up/shutdown and automatic unit operation within the full range of load changes.
