This complete process gas analysis system (hereinafter referred to as the system) is used for online monitoring of gas calorific value at various measurement points, including the analysis of CO, H₂, O₂, CH₄, analytical instruments, pretreatment devices, and their auxiliary application support components (standard gas). Through systematic design tailored to on-site application conditions and process gas sample conditions, the correct matching and reasonable combination enable CO, H₂, O₂, and CH₄ analytical instruments to adapt well to the special process conditions at various measurement points in gasifier projects for gas calorific value analysis. The system can automatically, continuously, accurately, and reliably analyze the content of CO, H₂, O₂, and CH₄ at each measurement point. During normal operation, the system can simultaneously provide 4–20mA standard output signals for CO, H₂, O₂, and CH₄, and output over-limit alarm status signals based on the measured component content values. The analytical instruments in this system are equipped with original imported sensors. The system features advanced technical solutions, simple structure, reliable component performance, high automation, easy operation, and minimal maintenance, making it an ideal device for gas calorific value monitoring.

This system mainly consists of a sampling unit, gas source purification unit, gas transmission unit, pretreatment unit, analysis unit, control unit, and calibration unit. It can be applied to various locations for monitoring calorific value in gasifiers. The system is characterized by safety, reliability, true sampling, fast response, high analysis accuracy, and flexible configuration and selection. It not only addresses adaptation to hazardous environments but also avoids the generation of unsafe factors within the system. Therefore, it is the most comprehensive gas calorific value analysis system in China.

Xi'an Juneng Instrument Co., Ltd. was recognized as a high-tech enterprise in 2008. The company has passed ISO9001 quality certification. In recent years, the analytical systems produced by the company have been widely used in various industries, not only receiving praise from large and medium-sized enterprises domestically but also being exported to India, Thailand, Vietnam, and other regions.

       The TR-9200 series online calorific value analysis system adopts a safety design tailored to the special gas environment of industrial pipelines with high dust and humidity, enabling multi-component concentration monitoring and calorific value analysis of industrial emission gases. Due to the high-temperature and dusty pipeline environment of industrial gases, sampling systems are prone to clogging. Our company provides targeted analysis and pretreatment solutions based on different working conditions, featuring professional multi-stage filtration and dust removal sampling probes to effectively ensure the accuracy and reliability of analytical data. The core components of the system are original imported products, ensuring high reliability and suitability for online concentration monitoring and calorific value analysis of industrial process gases or emission gases.

 System Composition:

    Pretreatment Unit: Consists of special liquid filters (scrubber, mist filter, desulfurizer, etc.) to complete intermediate purification of components such as tar and naphthalene; composed of condensers, peristaltic drain pumps, desulfurizers, fine filters, etc., to complete fine purification; composed of specially made corrosion-resistant suction pumps, flow controllers, etc., to handle gas sampling and stabilize pressure and flow. This ensures step-by-step purification, dust removal, dehumidification, pressure stabilization, and flow stabilization of gas samples, with a filtration accuracy of up to 0.1μm.     

     The qualified sample gas is delivered to the analytical instrument, ensuring the accuracy and long-term reliability of the analytical instrument. Analysis Control Interlock Unit: The magnetic oxygen analyzer performs online continuous analysis of oxygen content in the sample gas, continuously outputting 4–20mA signals. The oxygen analyzer is equipped with alarm output contacts, allowing alarm and interlock values to be set within the range. When the O₂ concentration exceeds the limit, an alarm and interlock are triggered.  For details, please contact: Jia Weihao 15891421187 18789429991 15891421187
