Power Plant Emissions & Power Station Emissions Monitoring (CEMS)
For more than 25 years, coal power plant emissions and biomass plant emissions have meant that the power generation industry has become the largest installed user base for Procal CEMS (continuous emissions monitoring systems). Throughout this period, there has been increasing environmental scrutiny and process upgrades, including the near-ubiquitous use of after-treatment systems such as sophisticated FGD and SCR.
Procal’s 2000 units are used in coal and biomass fired plants in Europe, USA and in the Asia Pacific region, including Europe's largest coal fired power plant, operated by Drax Power in the UK, where a total of eighteen units are installed. Drax have relied on Procal 2000 units for over 10 years of continued and reliable operation on coal and biomass top-up fired fuels. Assurance of availability is backed by a 24 hour service and maintenance agreement.
Procal 2000 units are used on plants to switch between fuels without adjustment to the analyser units, while still remaining in-tolerance for the applicable emissions limits. An example installation is operated by Endesa in Buenes Aires, Argentina, where five Procal 2000 units were installed between 2005 and 2007 on stack outlets from boilers operated on either oil or natural gas as a switchable fired fuel.
Diesel power plants are a frequent choice where rapid economic development outstrips the local grid capacity or remoteness precludes linkage with that grid. Often operating on variable load profile and frequent stop/start conditions, the systems require reliability, as service support will often be a remote resource. Procal's experience in this application covers island power plants and desert, tropical and marine-based diesel installations. As an example, Ace Power in Sri Lanka operate fourteen Procal 2000 units installed in 2004.
