Gas boiler nitrogen oxide detector

1、 Product Overview

Gas boiler nitrogen oxide detectorIt is aimed at the nitrogen oxides generated during the combustion process of gas boilers（NOx）A specialized analytical instrument for real-time monitoring of concentration. This device is based on high-precision gas sensing technology and intelligent data processing system, which can continuously collect boiler exhaust gas samples. Through professional detection modules, the gas concentration signal is converted into digital information, providing key data support for boiler combustion optimization, environmental compliance monitoring, and safety production management. Widely used in industrial gas boilers, commercial heating boilers, and small distributed energy stations.

3、 Main functional features

1. Real time monitoring and alarmUpdate data every second, whenNOxWhen the concentration exceeds the set threshold, sound and light alarms, relay outputs, and remote notifications (via SMS) will be triggered/APP）Reminder in various ways, alarm threshold supports multi-level customization

2. Combustion optimization assistanceAnalyze based on parameters such as boiler load and gas flow rateNOxGenerate trends to provide data basis for adjusting air-fuel ratio and combustion temperature, and help reduce nitrogen oxide emissions

3. Data recording and analysisBuilt in large capacity storage chip, capable of storing at least1Annual minute level historical data, supporting curve queries and daily reports/Monthly report generation and data export（CSVFormat), meeting the regulatory requirements of the environmental protection department

4. Intelligent self diagnosisEquipped with self checking functions for sensor faults, abnormal sampling flow, communication interruptions, etc., it automatically records fault information and prompts maintenance to ensure long-term stable operation of the equipment

5. Low maintenance designThe sampling probe is made of high-temperature resistant and corrosion-resistant materials, and is equipped with an automatic blowback cleaning system (which can be set with a cycle or manually triggered) to reduce manual maintenance frequency

4、 Installation and operation

1. Installation requirementsThe sampling point should be selected in the straight section of the boiler flue (at least downstream of disturbance sources such as elbows and fans)3Double the diameter of the pipe, at least upstream1.5Double the diameter of the pipe to ensure even gas mixing; The device host can be wall mounted or cabinet mounted, away from vibration sources and strong electromagnetic interference

2. operating interface: Equipped with7Inch color touch screen, Chinese menu interface, clear operation logic, supporting one click operation of functions such as parameter setting, data query, alarm recording, etc; Simultaneously provideWebEnd management platform and mobileAPPImplement remote monitoring and configuration

3. calibration method: Supports zero point calibration (with high-purity nitrogen or clean air) and span calibration (with standard gas), guided calibration process, supports automatic calibration (with optional calibration device)

5、 Application value

1. Environmental complianceReal time monitoring data can serve as the basis for the execution of pollutant discharge permits, avoiding fines for excessive emissionsAnd the risk of production stoppage, helping enterprises pass environmental inspections

2. energy conservation and consumption reductionBy optimizing combustion conditions, we can reduceNOxAt the same time as emissions, reducing gas waste. According to actual case studies, reasonable use can improve the thermal efficiency of boilers2%-5%

3. work safetyTimely detection of nitrogen oxide surge caused by abnormal combustion, prevention of poisoning accidents, and ensuring the personal safety of boiler room operators

4. Management upgradeReplacing traditional manual sampling and testing (with long cycles and high costs), achieving digital management, and improving the intelligence level of boiler rooms
