TurbineDustAlert

Supports gas turbine users with a focused online monitoring of air intake quality

Inlet air quality is a make-or-break factor of gas turbine performance

Stationary gas turbines require high levels of reliability. When located in dusty desert environments, this can be particularly challenging. To protect gas turbines from dust induced erosion and fouling, state-of-the-art air-intake systems measure the pressure drop across the air filters. However, how can one make sure that the air quality ” post filtration ” is at the required level? What monitors the actual performance of the air filtration itself?

TurbineDustAlert is an engineered solution specifically designed to focus on the air intake quality.

Up to 90% of power capacity loss of gas turbines is due to poor filtration of inlet air.

The gas turbine is affected by several substances in the inlet air with a variety in their composition and their particle size. The inlet filtration system cleans the air entering the gas turbine. However, if the filters lack efficiency, the turbine will be compromised. Both erosion and fouling will affect the optimum nominal shape of the blades, causing suboptimal operation. It is therefore critical to monitor air quality as it is going into the turbine and to receive alerts as soon as this quality is no longer in line with OEM standards.

TurbineDustAlert

TurbineDustAlert (TDA) is a simple device, plug and play and not expensive. It was designed to optimize turbine efficiency, protect turbines against excessive corrosion and fouling due to dust. TurbineDustAlert enables permanent monitoring of air filter performance thus operators can replace air filters based on actual filtration performance versus hours of service. Besides, TDA can be used to optimize air filter consumption using remote analytics. 

High Accuracy

High sensitivity and precision across all the measurements (temperature, pressure, PM0.5, PM1.0, PM2.5, PM4.0, PM10).

On-Board Data Storage

TDA can work in stand alone mode without connectivity. The data trends (PMs, pressure, temperature) are recorded on an internal SD card, which can be downloaded and analyzed by operators.

Satellite Connectivity

Besides using 4G/5G for offloading data, TDA can also use a satellite modem to offload basic readings to a low orbit satellite network. Worldwide subscription costs are only $20/month.

Sturdy & Plug-n-Play

TurbineDustAlert (TDA) is a simple device, firmly built and not expensive.

Additional Integrations

TDA can be integrated with the site-scada/DCS using e.g. Modbus RTU, Modbus TCP.

Monthly subscription

If a turbine user wishes to remotely monitor the air quality going into the turbine, several remote analysis packages are available. Additional remote support in setting alarm thresholds is included in the monthly subscription package.

Distinctive Algorithm

One of the distinguishing characteristics of the TurbineDustAlert is its algorithm. The principle of converting measured signal into mass concentration values is a one-of-a-kind feature of TDA.

Real-time dust classification

TurbineDustAlert allows the user to test five different air samples in real-time. This is being achieved by the use of 5 solenoid valves and implementation of laser-scattering principle.

Better Filtration – Better Turbine Performance

The cost of shutting down a turbine and washing the blades frequently is more than the cost of inlet filters replacement. Damage to the turbine blades is even more expensive. So the value of increased efficiency is high. Also, once a filtration system is in place, it is often not questioned further.

A relatively small investment in TurbineDustAlert will allow turbine users to ensure that the quality of the air effectively taken into the turbine – a fundamental operational parameter – is kept in check permanently!

Compromised filters mean compromised turbines!
