Guo Ruili Heng GR-3100D-6 Automatic Flue Gas and Particulate Emission Analyzer

Overview

The Guo Ruili Heng GR-3100D-6 Automatic Flue Gas and Particulate Emission Analyzer is a field-deployable, integrated environmental monitoring instrument engineered for regulatory-compliant stack emission testing at fixed pollution sources. It operates on the principle of isokinetic sampling using a Pitot tube, ensuring representative particulate collection across variable flue gas velocities (1–45 m/s). Simultaneously, it performs real-time electrochemical analysis of gaseous pollutants—including O₂, SO₂, CO, NO, NO₂, H₂S, and CO₂—alongside gravimetric determination of low-concentration particulate matter (PM) via filter-based weighing. The system integrates flue gas thermodynamics (temperature, pressure, humidity), flow dynamics, and compositional analysis into a single measurement sequence—eliminating the need for sequential probe swaps or manual recalibration between particulate and gas modes. Designed in accordance with Chinese national standards GB/T 16157-1996, HJ 836-2017 (low-concentration PM gravimetry), HJ 57-2017 (SO₂), HJ 693-2014 (NO_x), and HJ 973-2018 (CO), the GR-3100D-6 supports both routine compliance monitoring and performance evaluation of desulfurization, denitrification, and particulate control equipment.

Key Features

• 10.1-inch high-brightness capacitive touchscreen with dual-input mode (touch + physical keys) for operation under ambient lighting or gloved-hand conditions
• Multi-functional sampling probe: integrates Pitot tube, particulate filter holder (for glass fiber filter tubes or PTFE membranes), electrochemical gas sensor array, and resistive-capacitive humidity sensor in one rigid, titanium-alloy housing
• Probe-mounted local display showing real-time flue gas velocity, temperature, and moisture—enabling independent verification without main unit connection
• Simultaneous dust-gas sampling: concurrent particulate capture, gaseous pollutant analysis, and flue gas parameter logging eliminates procedural delays and inter-method variability
• High-flow capability: maximum sampling flow up to 100 L/min with isokinetic tracking maintained at up to 40 L/min across dynamic pressure gradients
• Industrial-grade embedded controller with ESD-hardened circuitry, automatic leak detection, self-diagnostic firmware, and power-failure memory retention
• Temperature-compensated electronic mass flow controller with integrated thermistor and piezoresistive pressure transducers for stable flow regulation under thermal drift
• Four-in-one cable assembly (power, analog signal, digital communication, and pneumatic line) with quick-connect fittings to minimize field setup time and reduce hose entanglement risk
• Cross-interference correction algorithm for electrochemical sensors, dynamically adjusting output based on co-existing gas concentrations per HJ 693-2014 Annex B guidelines
• Onboard data storage capacity ≥100,000 records; USB export support; optional Bluetooth thermal printer for immediate field reporting

Sample Compatibility & Compliance

The GR-3100D-6 is validated for use with standard EPA/ISO-compatible quartz fiber filter tubes (e.g., QAT-250) and hydrophobic PTFE membrane filters for low-concentration PM sampling per HJ 836-2017 and DB37/T 2537-2014. Its gas sensing module meets JJG 968-2002 metrological verification requirements for flue gas analyzers and JJG 695-2003 for H₂S detection. Humidity measurement conforms to HJ 870-2017 non-dispersive infrared (NDIR) principles for CO₂ and resistive-capacitive trace moisture detection. All operational parameters—including isokinetic ratio deviation, flow stability, and zero/span drift—are traceable to national calibration standards (JJG 680-2007). The system supports GLP-aligned data integrity through timestamped audit logs, operator ID tagging, and immutable record structure—facilitating internal QA review and third-party inspection readiness.

Software & Data Management

Data acquisition and reporting are managed via an embedded Linux-based firmware platform with ISO/IEC 17025-aligned metadata tagging. Each measurement record includes: sampling start/stop timestamps, probe ID, filter batch number, ambient barometric pressure, calibration gas lot numbers, and sensor diagnostic flags. Raw data exports as CSV files compatible with LIMS integration. Optional IoT module enables TLS-encrypted MQTT transmission to cloud-hosted environmental data platforms, supporting remote configuration updates, real-time alarm thresholds (e.g., exceedance of GB 13271-2014 limits), and fleet-level device health monitoring. All stored data complies with China’s Cybersecurity Law requirements for environmental instrumentation data sovereignty.

Applications

• Regulatory stack testing for coal-fired, biomass, and waste-to-energy boilers per GB 13271-2014 and provincial emission standards
• Performance verification of electrostatic precipitators (ESPs), fabric filters, wet scrubbers, and selective catalytic reduction (SCR) systems
• Low-concentration PM monitoring in ultra-low-emission retrofit facilities (≤10 mg/m³)
• Process optimization studies requiring synchronized flue gas composition and velocity profiling
• Environmental impact assessment (EIA) baseline surveys and post-commissioning compliance audits
• Research applications involving combustion efficiency analysis, sulfur capture ratio calculation, and NO_x formation pathway modeling

FAQ

What particulate concentration ranges does the GR-3100D-6 support?
The instrument is optimized for low-concentration particulate measurement (1–50 mg/m³) per HJ 836-2017, but also supports mid- and high-range sampling via adjustable filter media and flow rate selection.
Can the system be used for cooking oil fume sampling?
Yes—when equipped with the optional油烟 sampling probe (compliant with GB 18483-2001), the GR-3100D-6 meets all physical and thermal requirements for restaurant exhaust duct sampling.
Is the device certified for intrinsically safe operation in explosive atmospheres?
No—the GR-3100D-6 is rated for general industrial environments (IP54 enclosure); ATEX or IECEx certification is not available.
How often must electrochemical sensors be calibrated?
Per HJ 57-2017 and HJ 693-2014, zero/span calibration is required before each sampling campaign and after every 24 hours of continuous operation.
Does the instrument support automated report generation in English?
Yes—firmware v3.2+ includes bilingual (Chinese/English) report templates compliant with CNAS-CL01:2018 documentation requirements.
