Modernizing Old Plants to Meet New Demands
Much of the maintenance inspection in power plants is manual. Energy is wasted by steam loss and inefficiencies. Not all air and water emissions are checked. Imagine instead a power plant full of sensors that continuously monitor the condition of pumps and fans, detecting failure of steam traps or leaking relief valves, and where all emissions are monitored. Instead of operators collecting the data, the data comes to the operators. Much of the maintenance inspection in power plants is manual. Energy is wasted by steam loss and inefficiencies.

New Condiltion Monitoring Approach
There is a new way forward that takes a platform-based approach to condition monitoring and helps you to regain control of your maintenance mix. To overcome the challenges that the traditional maintenance mix presents, this platform must deliver: The flexibility of the solution to scale with your evolving needs, such as support for new types of algorithms, support for a wide variety of I/O and emerging sensors, and the ability to scale to large numbers of systems An openness that allows you to gain access to the raw engineering measurements to adapt to new and innovative analysis techniques and extend the solution to meet your maintenance program requirements Interoperability with third-party hardware and software packages so that you can integrate with existing CMMS and ERP systems and any database historians or process management enterprise software used Rugged mechanicals and a breadth of available algorithms A monitoring hardware and software solution for a price that allows you to scale your online condition monitoring solution to cover the bulk of your rotating machinery assets The services to help facilitate your end-to-end solution from your asset to your IT infrastructure, either directly or through a network of partners

Fleetwide Monitoring (FWM) is the implementation of applications for monitoring, maintaining and optimizing generation (and other) assets from a centralized location (Hussey, 2010). Fundamentally, FWM involves monitoring assets within a fleet of assets to detect operational and equipment problems earlier enough to mitigate damage, manage risk, identify performance problems, and manage business and market conditions or risks. A key part of FWM involves the use of advanced online monitoring technologies developed in the 1990s and 2000s and first applied in aerospace, transportation, and petrochemical applications. The goal of FWM is intelligent top-down approach to plant maintenance and scheduling. The goal is accomplished by the move toward centralized monitoring and diagnostic centers, the integration of advanced monitoring applications, and continued use of existing monitoring and maintenance technologies. The efforts supporting the goal will be facilitated by emerging standards supporting interoperability of equipment and technologies from multiple vendors.

Measuring Ammonia Slip from Post Combustion NOx Reduction Systems
In many facilities there may be room for process improvement that could reduce operating costs or provide revenue enhancement opportunities. Operating SNCR or SCR technology closer to its limit offers these benefits but increases the risk of high ammonia slip. The risk could be abated with the use of ammonia monitoring technology. But, except for gas-fired plants, continuous ammonia slip monitoring technologies have not been available at a practical price to facilitate these cost-saving or revenue enhancing improvements. Conditions that exist in high dust, high temperature, high NOx and/or high SO2 environments make most analyzer methods of continuously measuring ammonia unsuitable for application to coal plants. An overview of the technologies available for measuring ammonia in the high dust region downstream of a Nox reduction system and the status of their development is provided.

Constellation Energy installed SNCR systems at the CP Crane Station, units 1 and 2. These SNCR systems use continuous ammonia slip analyzers that work on the principle of tunable diode laser (TDL) spectroscopy and provide continuous, real-time indication of ammonia slip in the duct. These analyzers facilitated optimization of the SNCR system to avoid high ammonia slip transients that are the principal contributors to downstream problems normally associated with ammonia slip.

Predictive Emissions Monitoring is an option for gas turbine NOx measurement
Thomas Eisenmann is presenting a paper at CEM 2014 which explains why predictive monitoring is an option for the primary monitoring of gas turbines and duct burners or as a secondary measurement tool. PEMS offer significant cost benefits with lower capital expenditures as well as much lower operational and maintenance cost than CEMS. PEMS and DAHS require for operation very little or no plant manpower. CEM 2014 The 11th International Conference and exhibition on Emissions monitoring will take place in Turkey in the country’s financial and cultural capital, Istanbul, from the 14th – 16th May 2014.
