Real time corrosion monitoring for HRSG
Flow accelerated corrosion (FAC) can cause iron loss in steam piping and lead to lethal accidents. As a result, programs are necessary to reduce metal loss and to monitor the loss which does occur. A team from Danaher analyzed the problem in a Power Engineering article earlier this year.

Improving Plant Efficiency with Pump Performance and Condition Monitoring
Studies show pumps tend to be some of the more maintenance-intensive equipment in a plant, suffering a failure or some level of degraded operation on average every 12 months. Pumps in especially critical situations often have duplex and even triplex installations as backups, ready to switch over at a moment’s notice, such is their importance. Reactive maintenance, where it is necessary to fix something that has failed, costs 50% more than practicing predictive maintenance where problems can be detected and resolved before a failure. Pumps can be equipped with sensors to monitor condition and performance to ensure problems are detected as soon as possible so appropriate action can be taken…………... Over the last few years, the number of devices designed for equipment monitoring capable of operating on wireless networks has grown substantially. Some communicate using a plant’s Wi-Fi network, but a larger group has been designed to communicate via WirelessHART, the same network used by many types of wireless field instruments (Figure 2). The variety of low-power and low-bandwidth devices designed for these networks has grown enormously, and for all practical purposes, every type of monitoring device necessary for a full pump monitoring setup is available for use with WirelessHART networks.…………... Apps make it simple to perform real-time asset monitoring of a pump installation by identifying abnormal situations as they develop. Pre-packaged analytics evaluate health against unit history and industry norms, and the information is displayed via intuitive dashboards. All of this is possible with minimal configuration effort and no additional loading on the existing automation system. If desired, reporting and alarming functions can be added to external systems, but this is entirely optional.…………... New apps are available for health monitoring in conjunction with the wireless instrumentation, independent of the plant’s real-time automation system. These apps are easy to use because each is configured for a specific type of asset. Just as there are apps for pump monitoring, there are corresponding apps for other types of assets such as steam traps, heat exchangers, cooling towers, pressure relief devices, and more. This specialization helps deliver sophisticated analytics without having to create customized programming. The customization is already built into the platform, supporting fast implementation.……………

Coal analyzer at Hunter Station used to optimize coal blends
In order to estimate the ash fusion temperatures in the coal being sent to the power plant PacifiCorp Hunter Station needed an analyzer that could measure the ash constituents whose proportions determine ash fusion. The Gamma-Metrics Coal Quality Manager (CQM) analyzer from Thermo Electron Corporation provides minute-by-minute analysis of SiO2 , Al2 O3 , Fe2 O3 , CaO, TiO2 , K2 O, and Na2 O in the ash. PacifiCorp installed one of these units in its coal yard to blend coals of differing ash composition, in order to keep the blended coal’s ash softening temperature above 2175degrees F. In order to take advantage of the potential of this instrument several steps had to be taken. First the analyzer had to be rigorously calibrated and evaluated in the field to verify that the desired accuracy was achieved. Meanwhile the utility had to analyze its boiler characteristics and coal characteristics to be able to derive an ash fusion equation appropriate to the plant. Then the necessary operational steps had to be taken to ensure that source coals capable of achieving the target blend could be initially segregated and then blended at the correct ratios. After some startup difficulties, the analyzer and the blending system have been very successful in maximizing the ash softening temperatures, and the plant has substantially reduced its forced outages due to slagging while burning a variety of available fuels.

Yokogawa instrumentation for efficient combustion control
Use of gas measurement with TDL improves combustion efficiency and lowers emissions. Tunable Diode laser spectroscopy ( TDLS) using infra red ( IR) technology can measure a number of gases including oxygen. This presentation from a 2015 industrial conference in Europe shows an example where the Yokogawa TDLS was used to reduce excess air from 3.5% to less than 1 %. Yokogawa and its competitor Zolo are supplying TLDS analyzers. In Pacific Corp session 1 the Yokogawa analyzer was mentioned. So this paper is being added to the intelligence system with the expectation that more specifically applicable information will be forthcoming.

Regional haze ruling for Pacific Corp
This July 5 2016 Federal register document partially approves and disapproves the original Utah plan. It rules that the BART alternative submitted in the Utah plan is not acceptable relative to NOx emissions at 4 units located at the Hunter and Huntington plants in Utah.

ABB demonstrated the advantages of ICOS for HCl measurement at EUED
Summary Proved accurate and reliable measurement at 1ppm HCl Demonstrated compatibility with 100:1 dilution system Optimizing response time of system using glass coated or chemically treated materials makes sense, but… …unless analyzer is installed close to sample probe, injecting dry test gas into the system on daily basis makes little sense Shown that 95% step change in under 15 min. can very likely be achieved using vaporized liquid standards (i.e. HovaCal) Illustrated importance of H2O to validate HCl measurement Speed and accuracy of ABB Off-Axis ICOS analyzer is extraordinary considering no field calibration was performed
