I. Addressing Thermal Power Measurement Pain Points with 120G Radar Precision

The complex processes and harsh operating conditions of thermal power generation pose multiple challenges for traditional measurement methods, hindering production efficiency and safety:

Coal Storage Link: Coal in large silos is prone to "bridging" and "wall-hanging" phenomena. Traditional level gauges often have their signals blocked by coal dust and cannot penetrate coal seam gaps, leading to distorted level data. Minor inaccuracies cause uneven coal feeding, affecting boiler combustion efficiency; severe cases result in silo blockages that require shutdowns for cleaning, directly reducing power generation output.

Boiler System Link: Drum water level is a core indicator for safe boiler operation. Traditional differential pressure level gauges are highly sensitive to temperature and pressure fluctuations, prone to zero drift, and their sealing performance may fail under high-temperature and high-pressure environments, posing safety risks. Meanwhile, oil in boiler fuel tanks is liable to stratification due to temperature changes, making it difficult for traditional instruments to accurately measure the actual liquid level, which impacts the stability of fuel supply.

Desulfurization and Denitrification Link: Absorption towers contain high-concentration, highly corrosive slurry, accompanied by a large amount of foam and spray mist. Traditional ultrasonic level gauges have signals reflected by foam and attenuated by mist, failing to accurately monitor slurry levels. This leads to uncontrolled desulfurizer dosage, reduced desulfurization efficiency, and even the risk of non-compliance with environmental standards.

Ash and Slag Treatment Link: Electrostatic precipitator hoppers and ash silos have extremely high fly ash concentrations. Traditional radio frequency admittance level gauges are susceptible to dust adhesion, resulting in frequent false alarms that cause ash discharge equipment to run idly or overload, increasing equipment wear and operation and maintenance costs. Additionally, slag slurry in slag ponds has high solid content and poor fluidity, easily clogging traditional level gauges and preventing real-time level monitoring, which affects the operation of the slag discharge system.

Chemical Water System Link: Media in demineralized water tanks and acid-alkali storage tanks are highly corrosive to equipment. Traditional contact-type level gauges are prone to corrosion damage, and maintenance requires shutdowns and emptying, affecting the continuity of chemical water supply and further disrupting the stability of the steam-water circulation system.

With technological breakthroughs, the SOLIDAT 120G Radar provides "customized solutions" for the pain points of thermal power generation scenarios:

Ultra-High-Frequency Narrow-Angle Focus Technology: Operating at 120G Hz with an emission angle as narrow as 2°, it can accurately avoid interference sources such as wall-hanging coal in silos, foam in absorption towers, and dust in ash silos. It penetrates coal seams and dust gaps to directly capture the real medium surface, achieving a measurement accuracy of ±1mm and completely solving the "poor visibility" problem of traditional instruments.

Superior Environmental Adaptability: The sensor housing is made of 316L stainless steel with a high-temperature sealed structure, capable of withstanding extreme temperatures from -40℃ to 300℃ and high pressure up to 40MPa. With an IP68 protection rating, it is dustproof, waterproof, and corrosion-resistant, ensuring stable operation in both high-temperature boiler drums and acid-alkali storage tanks.

Anti-Adhesion and Anti-Interference Design: The sensor surface is coated with a Teflon anti-stick layer, effectively preventing the adhesion of fly ash, slurry, oil, and other media to avoid signal attenuation. Meanwhile, its 120dB ultra-high dynamic range and intelligent signal filtering algorithm automatically filter foam, mist, and electromagnetic interference, ensuring stable and reliable signals and solving the "easy failure" problem of traditional instruments.

Non-Contact Measurement Advantage: Without direct contact with the medium, it avoids corrosion, wear, and other issues, boasting a service life of over 10 years, which significantly reduces equipment replacement and maintenance frequency. Moreover, measurement is not affected by changes in medium density, viscosity, or dielectric constant, making it suitable for all types of media from coal to acid-alkali liquids.

Intelligent Linkage Function: Supporting multiple communication protocols such as Modbus, Profinet, and 4G, it can seamlessly integrate with the power plant's DCS and SIS systems, enabling real-time upload of measurement data, remote monitoring, and intelligent early warning. This facilitates the intelligent upgrading of production scheduling and equipment management.

Its narrow-angle focus technology penetrates high-concentration dust in silos to monitor coal height in real time. It supports linkage with coal feeders and coal conveyor belt systems, automatically adjusting coal feeding volume and speed based on coal levels to prevent silo emptying or overflow. Additionally, through historical data trend analysis, it can predict coal consumption rates, optimize coal procurement and inventory management, and reduce coal storage costs.

2. Boiler and Steam-Water Circulation Link

In core equipment such as boiler drums, feed water tanks, deaerators, and fuel tanks, the 120G Radar plays a key monitoring role. For drum water levels, its high-temperature and high-pressure adaptability and precise measurement capabilities enable real-time water level data output, providing a basis for the DCS system to adjust feed water valves. This ensures drum water levels remain within a safe range, avoiding "flooding" or "water shortage" accidents. For fuel tanks, it accurately measures oil levels at different temperatures, ensuring on-demand fuel supply and stable combustion during boiler ignition and stabilization phases. For deaerators, it monitors water level changes in real time to optimize deaeration effects and reduce pipeline corrosion.

3. Desulfurization, Denitrification, and Environmental Treatment Link

Level monitoring of equipment such as desulfurization absorption towers, denitrification ammonia water tanks, and slurry circulation tanks is directly related to meeting environmental standards. The 120G Radar's anti-foam and anti-corrosion capabilities allow accurate measurement of slurry levels in absorption towers, preventing spray idling due to excessively low levels or waste from overflow due to excessively high levels. Meanwhile, real-time monitoring of ammonia water tank levels ensures stable supply of denitrification reducing agents, helping power plants meet ultra-low emission requirements. Additionally, it achieves precise level monitoring in auxiliary equipment such as limestone slurry tanks and gypsum dewatering systems, ensuring the continuous operation of the desulfurization system.

4. Ash and Slag Treatment and Chemical Water System Link

Level monitoring of equipment such as electrostatic precipitator hoppers, ash silos, and slag ponds is critical for the efficient operation of the ash and slag treatment system. The 120G Radar can penetrate high-concentration fly ash in hoppers to monitor ash levels in real time, preventing ash blockages or idling of ash discharge valves. In ash silos, it accurately measures ash levels and supports linkage with dry ash bulkers and wet ash mixing systems, optimizing ash transportation and comprehensive utilization. In the chemical water system, its non-contact measurement method avoids medium corrosion of equipment in demineralized water tanks and acid-alkali storage tanks. Real-time level monitoring ensures stable chemical water supply and compliance with water quality standards in the steam-water circulation system.
