This article deeply analyzes its core competitiveness from three dimensions: technical characteristics, application advantages, and industry value.

1、 Core feature: Technological innovation drives precise monitoring

1. Multi parameter integrated detection capability

This instrument breaks through the limitations of traditional single function detection and achieves synchronous measurement of four parameters: acid dew point temperature, oxygen content, water dew point value, and moisture content. For example, in boiler flue gas monitoring, it can simultaneously output0℃～200℃Acid dew point value1ppm～25%Oxygen content0～100%Water vapor content and-50℃～100℃Dew point value provides multidimensional data support for process control. This integrated design reduces equipment redundancy and lowers enterprise procurement and maintenance costs.

2. Intelligent Algorithm and Adaptive Correction

The built-in intelligent system can automatically correct interference factors such as fluctuations in smoke composition and pressure changes through dynamic environment compensation algorithms. For example, during fuel switching (such as switching from natural gas to coal), the instrument can adjust the sulfur content of the fuel according to the preset settingsSO₃Conversion rate model, real-time adjustment of acid dew point calculation parameters to ensure measurement accuracy≤±2℃In addition, it has an automatic calibration function that can regularly monitor sensor status and compensate for drift, reducing the need for manual intervention.

2、 Application advantages: equal emphasis on cost reduction, efficiency improvement, and safety control

1. Energy efficiency improvement and cost savings

By precisely controlling the exhaust temperature, enterprises can significantly reduce fuel consumption and equipment wear and tear. For example, a certain thermal power plant will adjust the exhaust temperature from160℃Optimize to145℃Afterwards, the thermal efficiency is improved1.2%Annual fuel cost savings exceed200Ten thousand yuan; At the same time, the corrosion rate of the heated surface at the rear decreases65%The maintenance cycle has been extended to3In the year, the indirect reduction in maintenance costs exceeded one million yuan.

2. Security risk prevention and control

Real time monitoring of acid dew point temperature can prevent equipment leaks, explosions, and other accidents caused by low-temperature corrosion. For example, in a waste incineration plant, if the exhaust temperature is lower than the acid dew point, sulfuric acid vapor will corrode the wall of the waste heat boiler, causing steam leakage or even shutdown.N2035Apass2Passive node alarm output can immediately trigger interlock protection when the acid dew point exceeds the standard, ensuring production safety.

3. Environmental compliance support

This instrument can assist enterprises in meeting the "Boiler Air Pollutant Emission Standards"（GB 13271-2014）Waiting for regulatory requirements. For example, by monitoring the sulfur content and acid dew point of flue gas, optimizing desulfurization process parameters, and ensuringSO₂emission concentration≤35mg/m³To avoid environmental penalties caused by excessive emissions.
