Fully Automating HRSG Feedwater Pumps
Even a relatively simple start-up process can have many steps and delays for operator cross-checks. Automation can simplify the procedure for the operator while reducing start-up time. In addition, more sophisticated controls techniques may be applied to improve process stability, reduce energy usage, and increase operating flexibility. Modern distributed control system (DCS) platforms offer capabilities that were unavailable just a few years ago. Features such as integrated graphical engineering environments, simplified sequencing controls, and improved human-machine interfaces (HMI) make higher levels of automation more practical from the standpoints of implementation, maintenance, and ease of use. The timing of these advances couldn’t be better—critical operating personnel throughout the power industry are approaching retirement age, and there are insufficient numbers of skilled younger personnel to replace them. Leveraging the existing plant knowledge base to design automation that reduces the burden on plant operators will be essential to meeting tomorrow’s plant demands. As an example, the following case study describes automating a simplified feedwater system for a combined-cycle power plant. The existing legacy DCS controls are proven and reliable; however, the sequence of operations and coordination of regulatory controls is not automated, therefore, it requires a high degree of knowledge and attention on the part of the operator. This case study describes a combination of controls automation strategies and HMI techniques designed to increase the overall level of automation while improving ease of use by operators and maintenance personnel.

Gas Turbine Intake Filter Sales To Exceed $1 Billion By 2021
Sales of gas turbine intake filters will double over the next six years according to the McIlvaine Company. The high rate of revenue growth will be a function of not only robust unit growth but double digit growth in the revenue per unit. Gas turbine power generation is increasingly attractive due to the low price of natural gas, the environmental restrictions on coal-fired power and the ability for system suppliers to deliver new plants within 24 months. The latest high performance turbines provide improved efficiency and lower CO2 emissions per unit of energy produced. However, the rotating equipment is subject to substantial corrosion and erosion from small particles.

The Power of Flexibility: Turbine Inlet Air Chilling Benefits
Gas turbines are constant volume air intake machines; consequently, air mass flow and resultant power output fall as ambient temperatures rise and air density falls. The purpose of Turbine Inlet Air Chilling (TIAC) is to restore the power output of a combustion turbine at elevated ambient temperatures to its rated capacity or better. As the critical 'operating system' of the TIAC enhancement, the control technology also plays an integral role in maximizing operational flexibility.

The Value Proposition Offered by HEPA Filtration
The cost of an E12 HEPA filter may be as much as four or five times the price of a conventional air filter. Economic analyses conducted by owners have typically focused on compressor performance and assumed a one- to two-year lifetime for HEPAs serving high-hours engines. Based on those parameters alone the HEPA was, and continues to be, a tough sell. But where the cost of replacement power is expensive or unavailable, water washing is not feasible, or a corrosive ambient environment is causing premature engine failure, HEPA filtration may be readily justified.

Electric Fuel Control Valve Streamlines Plant Operations
A Frame 6B-powered cogen plant in California was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. One solution is to reheat the fuel gas to above the dew point (120-130F) in between the valves, but this is considered far from ideal. The better solution proved to be replacing the original valve with a “smart” electric control valve in the same location as the original and a separate solenoid-operated stop/isolation valve about 6 ft upstream—just outside and below the turbine enclosure.

Quickly Boost Your Combustion Turbine Response
PowerPhase LLC has developed a new technology called TurboPHASE, a fast-responding, modular “turbocharger,” that can boost the capacity of an existing simple cycle or combined cycle plant by 10% or more in seconds. The system consists of a compressor that delivers hot compressed air to the discharge section of a combustion turbine, thereby allowing it to operate at the rated capacity irrespective of ambient air temperatures. Morris Cogeneration, a combined cycle cogeneration plant near Chicago, installed TurboPHASE, to boost capacity when needed during cold weather events.

The Rewards of Pump System Optimization
Typically, when talk turns to power plant pumps, boiler feed and cooling water pumps immediately dominate the discussion. And that’s as it should be: these pumps are critical to a plant’s thermal efficiency and availability. They are also the most costly to produce, operate and maintain, so optimizing their efficiency is imperative. However, in terms of reliability and profitability for the entire plant, it is also prudent (and economically rewarding) to optimize pump system performance throughout the entire station.

Nanofiber Media Performance in Application to Motor Vehicle Air Filtration
The function of air filtration systems in motor vehicles is to improve air quality and cleanliness in car interior, control the respirable particle concentration in the operator’s cabin, and reduce the dust concentration in the engine intake air to an acceptable level. In these applications, limited space is available for the air filtration systems. Therefore, filters are designed in smaller packages, resulting in higher aerosol velocities through the filters. Such high aerosol velocities may cause dust reentrainment leading to an increase in the amount of dust penetrating the filter. Moreover, motor vehicle environments are extremely varied and these environmental and operational conditions influence filter performance.

Improved Reliability of High-AVT (High-pH Water Treatment) Application to Combined Cycle Plants
Generally in the water treatment of combined cycle plants, ammonia and hydrazine are used in the feedwater system and phosphates are used in the boiler system. However, in Mexico, the Tuxpan No. 2 and No. 5 power plants have adopted “High-AVT (high-pH water treatment),” in which ammonia is used to set the pH of feedwater higher than the conventional level, requiring no phosphates in the boiler system. In response to such good operational results, MhI introduced high-AVT as an option for the water treatment of combined cycle plants.

Planning Upgrades: Evaluate the Regulatory Impacts of Upgrades Before you Buy
One ongoing study at NV Energy involves identifying possible upgrades for existing assets. Staff Engineer Susan Hill says that no particular upgrade can be applied across the utility’s fleet due to differences in regulatory requirements. For example, about three-quarters of NV Energy’s capacity is in southern Nevada, specifically Clark County; most of the remainder is in northern Nevada, relatively close to Reno. Some Clark County assets are in PM10 non-attainment areas; plus, ozone rules are not well defined for the county going forward. Northern plants are in an attainment area.

AIG Tuning, Catalyst for Life Forecasting
Many gas-turbine “bubble” units installed between 2000 and 2004 are operating with their original charge of SCR catalyst. These units have outlived the original catalyst warranty (typically three years) and have benefitted from a combination of conservative design and good luck. However, as these systems reach the decade mark, the design margins have diminished because of gradual (and inevitable) deactivation of the catalyst with age. As the catalyst nears its end of life, ammonia slip begins to increase exponentially. There are practical steps operators can take to avoid this scenario.

Engineered solution improves SCR performance significantly
Getting gas-turbine inlet air and exhaust gas to flow where and how you want it to in powerplant ductwork is akin to herding cats. The problem, as described by industry veterans Jim Carlton, president, Granite Ridge Energy LLC, and Larry Hawk, plant engineer, Granite Ridge Energy, operated by NAES Corp, was that the plant had been challenged by an underperforming NOx catalyst since commissioning. However, routine destructive sampling of the catalyst showed reactivity at or above expectations. And testing confirmed that the ammonia injection grid was properly balanced. What to do?

How to Reduce Catalyst Lifecycle Cost, Improve Reliability
Balancing the requirements of each SCR system in the fleet can be challenging. A system can reduce NOx by greater than 95%, but when the efficiency of the SCR is pushed beyond 85% and—or, if—the outlet emissions are less than 5 ppm, the system becomes much more sensitive to several independent system parameters. These include overall catalytic potential, effective ammonia injection/mixing in the flue-gas stream, flue-gas characteristics for inlet NOx, velocity, and temperature distributions.

Vokes recommends combining coalescer and pre filter
In locations with high levels of atmospheric moisture (such as Northern Europe, equatorial or coastal sites), a coalescer protects against water and is typically followed by coarse and fine dust filter stages. This coalescer stage usually consists of a bank of G3 or G4 glass fibre pads treated with a water resistant coating. Such elements retain moisture well, but can quickly become clogged at higher air flows and as they become dirty, choking the air flow and raising differential pressure. Now, thanks to developments in media technology, a handful of products are available that offer an alternative approach by combining the water coalescer and pre-filter stages into one-unit.

GE announced the availability of its new GE TS1000 coalescer, a gas turbine filtration product that delivers improved plant performance and lower maintenance costs to customers operating power generation facilities in harsh conditions near coastal environments. The new TS 1000 will not need to be replaced as frequently due to its unique media, which allows sand and dust to pass through, therefore not clogging the coalescer.
