Junray ZR-3260E Flue Gas and Particulate Analyzer (Direct-Reading, Compliant with GB/T 16157-1996)

Overview

The Junray ZR-3260E Flue Gas and Particulate Analyzer is a portable, field-deployable integrated instrument engineered for regulatory-compliant emissions monitoring from stationary sources. It operates on dual-path measurement principles: gravimetric particulate determination via isokinetic sampling and filter-based mass collection—aligned with the weight-based methodology in GB/T 16157-1996 and HJ 836-2017—and real-time gaseous pollutant quantification using a hybrid sensor architecture. Gaseous analytes—including SO₂, NO, NO₂, NOₓ, CO, CO₂, H₂S, and O₂—are measured concurrently using ultraviolet differential optical absorption spectroscopy (UV-DOAS), non-dispersive infrared (NDIR), and electrochemical sensing technologies. The system supports direct-reading capability for particulate matter when coupled with the optional ZR-D09QT beta-ray absorption probe, enabling on-site mass concentration reporting without laboratory gravimetry. Designed for fixed-source stack testing, the ZR-3260E delivers synchronized acquisition of flue gas velocity, temperature, static/dynamic pressure, dew point, oxygen content, and excess air coefficient—parameters essential for emission rate calculation, efficiency assessment of abatement devices (e.g., ESPs, scrubbers), and compliance verification under Chinese environmental standards.

Key Features

• Isokinetic sampling control with microprocessor-driven flow tracking, ensuring representative particulate capture across variable flue velocities.
• Dual-mode particulate measurement: standard gravimetric (filter-tube weighing per HJ 836-2017) and optional beta-ray absorption (ZR-D09QT probe) for real-time PM concentration output.
• Multi-gas detection platform integrating UV-DOAS (for SO₂, NOₓ), NDIR (for CO₂, CO), and electrochemical cells (for O₂, CO, H₂S, NO, NO₂), each calibrated per HJ 57-2017, HJ 693-2014, and HJ 973-2018.
• Integrated flue parameter module measuring temperature (−20 °C to 200 °C), pressure (±5 kPa), velocity (via certified Pitot tube per JJG 518-2023), and humidity (optional resistive-capacitive probe interface).
• Intelligent flow management: high-torque, low-noise diaphragm pump with electronic mass flow controller; automatic temperature/pressure compensation (TPC) and real-time flow regulation.
• Rugged human-machine interface: sunlight-readable, wide-angle color LCD with touch + tactile keypad; industrial-grade IP65-rated housing; cold-resilient operation down to −20 °C.
• Onboard data integrity: internal flash memory with timestamped, audit-ready records; automatic calibration log storage; CPA-certified metrological traceability (China National Metrology Approval).

Sample Compatibility & Compliance

The ZR-3260E is validated for use across coal-fired boilers, industrial kilns, waste incinerators, and catalytic cracking units. It accommodates diverse sampling configurations—including standard ZR-D25A multi-parameter probe, low-concentration ZR-X01 nozzle kit, and optional asphalt/oil mist sampling attachments—ensuring adaptability to high-dust, high-moisture, or corrosive exhaust streams. Regulatory alignment includes full conformance with GB/T 16157-1996 (particulate and gas sampling methodology), HJ 870-2017 (CO₂ by NDIR), HJ/T 48-1999 (sampler performance criteria), and DB37/T 2537-2014 (Shandong provincial low-PM protocol). All gas sensors undergo periodic verification per JJG 680-2021 (sampler calibration) and JJG 968-2002 (analyzer verification), supporting GLP-aligned field audits and QA/QC documentation requirements.

Software & Data Management

Data acquisition and reporting are managed via embedded firmware compliant with ISO/IEC 17025 traceability frameworks. The system logs raw sensor outputs, corrected concentrations, isokinetic deviation indices, and environmental metadata (stack ID, date/time, operator code) into encrypted binary files. USB, Bluetooth 5.0, and optional Wi-Fi enable secure transfer to Junray’s desktop analysis suite (Junray EmissionSuite v4.x), which generates EPA-style reports—including normalized concentration (e.g., 6% O₂), emission rates (kg/h), removal efficiency (%), and uncertainty budgets per GUM (Guide to the Expression of Uncertainty in Measurement). Audit trails record all parameter edits, calibration events, and user logins—meeting baseline expectations for 21 CFR Part 11–compatible electronic records in third-party verification contexts.

Applications

• Regulatory stack testing for SO₂, NOₓ, CO, and particulate matter under China’s “Blue Sky Protection Campaign” enforcement protocols.
• Performance evaluation of desulfurization (FGD) and denitrification (SCR/SNCR) systems via inlet/outlet paired measurements.
• Low-concentration particulate monitoring in post-ESP or wet scrubber ducts per HJ 836-2017.
• Combustion optimization studies via O₂ and CO co-monitoring to determine excess air ratio and incomplete combustion indicators.
• Field validation and accuracy assessment of CEMS (Continuous Emission Monitoring Systems) per HJ 75-2017.
• Mobile source emission surveys and fugitive dust characterization when deployed with portable dilution tunnels.

FAQ

Does the ZR-3260E support automatic correction for CO interference on SO₂ electrochemical sensors?
Yes—the instrument includes configurable CO cross-sensitivity compensation logic per HJ 57-2017 Annex B, with user-adjustable correction coefficients and toggleable activation.
Can historical sampling configurations be recalled for repeat stack tests?
Yes—the onboard烟道 database stores up to 500 stack profiles (diameter, temperature range, expected velocity), enabling one-touch reconfiguration and reducing setup time by >40% in multi-point campaigns.
Is the beta-ray direct-reading module (ZR-D09QT) factory-integrated or field-upgradable?
It is an optional field-installable module requiring mechanical coupling to the main unit and firmware update; no hardware modification of the base analyzer is needed.
What power options are available for extended unattended operation?
The unit accepts 24 V DC (external battery pack), 100–240 V AC (with universal adapter), and vehicle cigarette lighter input; internal Li-ion backup sustains operation for ≥4 h during main power interruption.
How is moisture management handled during high-humidity sampling?
The ZR-V01 condensate separator provides active vapor removal; optional resistive-capacitive humidity probe (HJ 836-2017 compliant) enables real-time moisture correction for dry-basis concentration reporting.
