Level Measurement For Power Plants, Coal And Fly Ash
Power plants require reliable level measurement for coal bunkers, fly ash silos, lime slurry tanks, desulfurization systems, ash handling equipment, wastewater tanks and process storage vessels. SHAO provides level measurement solutions for dusty, abrasive, high-temperature and harsh working environments in power generation facilities.

Why Power Plant Level Measurement Requires Durable Solutions
Power plants often handle difficult materials such as coal, lignite, coke, fly ash, coal powder, lime slurry and wastewater. These applications may involve heavy dust, high temperature, abrasive solids, sticky ash, slurry, foam, vibration and outdoor installation conditions. A suitable level measurement solution should consider material state, silo height, process temperature, dust concentration, installation position and control requirements.

Main Challenges In Power Plant Level Measurement
Power generation facilities often require level measurement devices that can withstand dust, vibration, abrasion and harsh process environments.
Fly ash and coal powder may create heavy dust during filling and discharge.
Coal, coke and ash may form uneven surfaces inside silos and bunkers.
Slurry tanks may contain foam, sediment, agitation and buildup.
Outdoor installations may face moisture, dust and temperature changes.
Abrasive solids can affect sensor durability and long-term reliability.
Power plant automation requires stable output and alarm signals.

Frequently Asked Questions
What level sensor is suitable for fly ash silos?
Radar level meters are often used for continuous fly ash silo level measurement because they provide non-contact measurement in dusty storage conditions. A solid level switch may be used for high or low alarm.
Can radar level meters measure coal bunkers?
Yes. Radar level meters can be used for many coal bunker applications, but dust, silo shape, installation position and material surface condition should be confirmed before selection.
Which solution is suitable for lime slurry tanks?
Lime slurry tanks may use radar level measurement or pressure level transmitters depending on agitation, sediment, foam, tank size and installation requirements.
How do dust and ash buildup affect measurement?
Dust may weaken the measuring signal, and buildup may affect the signal path or sensor surface. Proper sensor selection and installation position are important for stable measurement.
What information should I provide before requesting a quotation?
Please provide medium type, silo or tank size, measuring range, temperature, dust condition, foam or agitation condition, installation method, output signal requirement and site photos if available.
