Product Overview
The Portable Gas Analyzer (Coal Gas) integrates Non-Dispersive Infrared (NDIR), long-life electrochemical sensors, and MEMS thermal conductivity technology to simultaneously measure the calorific value of coal gas and biogas while analyzing the volume concentrations of CO, CO₂, CH₄, H₂, O₂, CₙHₘ, and other gases. Its portable design allows for industrial field measurements and laboratory gas sampling, efficiently replacing traditional combustion calorimeters. The analyzer is ideal for coal gas and natural gas calorific value measurement and multi-component gas analysis.
Technical Principles
- NDIR Technology: Measures CO, CO₂, CH₄, and other infrared-absorbing gases.
- Electrochemical Sensors: Measures O₂, H₂, and other reactive gases with high precision.
- MEMS Thermal Conductivity: Determines the calorific value of CₙHₘ gases.
- This combination allows simultaneous multi-component gas measurementand accurate calorific value calculation without mutual interference.
Key Features
- Multi-Gas and Calorific Value Measurement: Measures CO, CO₂, CH₄, H₂, O₂, CₙHₘ simultaneously and calculates coal and natural gas calorific value automatically.
- High Measurement Accuracy: Each gas component does not interfere with the measurement of others. For example, CₙHₘ does not affect CH₄ measurement; CO, CO₂, CH₄ do not interfere with H₂ measurement.
- Portable Design: Lightweight and compact, ideal for field operation and laboratory gas bag sampling.
- Smart Power Management: Built-in battery management with soft-start power control, extending battery life.
- Efficient Data Management: Automatic data storage, with options for query, deletion, and multiple data interfaces.
- Low Operating Cost: No disassembly, chemical reagents, or consumables required; simple, cost-effective operation.
Applications
- Coal Gas and Natural Gas Monitoring: Field measurement and calorific value analysis of coal gas, natural gas, and biogas, including coke oven gas and mixed coal gas.
- Industrial Sites: Monitoring combustion processes in power, petrochemical, and chemical industries to improve fuel efficiency and save energy.
- Laboratory Analysis: Accurate sampling and analysis of coal and natural gas compositions for research and quality control.
- Environmental Monitoring: Measures CO, CO₂, H₂, and other emissions to ensure compliance with environmental standards.
- Energy Management: Real-time tracking of fuel calorific value to optimize energy consumption and reduce costs.
