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.

Pressure Loss of Air Filters for General Ventilation at High Relative
In anticipation of the new European standard EN 779.2012 for air filters, which classifies air filters based on their lowest filtration efficiency, this article discusses the effect that high humidity has on pressure loss during exposure to different dusts. For example, individual test data show that variations of relative humidity cause significant changes in pressure loss if NaCl is present in the loading aerosol.

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.

Recent Development in Heavy Duty Engine Air Filtration and the Role of Nanofiber Filter Media
The development of an engine air filter is based on filter performance requirements, vehicle’s operational environment, available space, filter media properties, and production technology. The design process includes analyses of theoretical and empirical models describing filter media performance and aerosol flow in filter housings and through filter elements. Filter media are carefully selected based upon these models and simplified laboratory tests. The filter element design is evaluated in great detail through a series of laboratory and field experiments.

Overview of Nanofibers Applications for Air Cleaning
The Need for Air Cleaning Air filtration intake systems perform a number of functions including reducing intake noise and removing moisture. Clean air is needed to prevent wear of moving parts and prevent workers in high dust environments from developing respiratory problems. All of air contaminants entering equipment can and will lead to unnecessary wear, shorter machine life, and increased maintenance costs.

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.

HEPA Air Filtration Technology Keeps Compressor Blades Clean
Combustion turbine operators generally experience turbine fouling from airborne particles passing through existing inlet air filters. Fouling can be caused by the particle capture limitations of conventional F-class (EN779:1998) or MERV-class (ASHRAE 52.2) filters. The consequence is reduced performance of the turbine operation.

Chiyoda - Gas Turbine Suction Air Cooling System
The power output of a gas turbine decreases when the suction air temperature of an auxiliary combustion air compressor increases, and the flow rate of air decreases. Therefore, gas turbines cannot maintain the rated power in the summer. The power of a combined power plant or a gas turbine power plant can be increased substantially compared with conventional systems with a system that cools the suction air with heat recovery from LNG in the summer.

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.
