Overview
The Junray ZR-3260B Automatic Stack Emission Analyzer is an integrated, field-deployable instrument engineered for comprehensive emission monitoring at stationary sources. It combines gravimetric particulate sampling with electrochemical gas sensing to simultaneously quantify both suspended particulate matter—including ultra-low concentration PM (e.g., < 5 mg/m³)—and key gaseous pollutants in flue gas streams. The system operates on the principle of isokinetic sampling for particulates (per GB/T 16157-1996 and HJ 57-2017), while gaseous analytes are measured via standardized potentiostatic electrolysis (HJ 693-2014 for NOₓ, HJ 973-2018 for CO, HJ 57-2017 for SO₂). Built-in thermocouple-based temperature sensors, diaphragm-type differential pressure transducers, and dual-mode humidity interfaces (dry/wet bulb or capacitive) enable full stack parameter characterization—dynamic pressure, static pressure, flue gas temperature, moisture content, and volumetric flow rate under standard dry conditions (Nm³/h). All calculations—including normalized concentrations (e.g., 11% O₂ reference), emission mass flux (kg/h), and desulfurization/dedusting efficiency—are performed in real time per Chinese national standards and aligned with internationally recognized methodology frameworks.
Key Features
- Integrated isokinetic particulate sampler with automatic condensate ejection via built-in diaphragm pump—optimized for high-humidity stacks (up to 95% RH) without manual drainage.
- Dual-operation interface: 5.0-inch wide-temperature TFT color display with multi-angle flip mount; supports both capacitive touch and sealed industrial keypad input with IP65-rated dust/moisture resistance.
- High-capacity sampling pump delivering up to 80 L/min flow, coupled with precision electronic mass flow control and real-time temperature/pressure compensation (T&P sensor feedback loop).
- CO interference correction algorithm for SO₂ measurement: user-configurable correction coefficient based on empirical interference testing, compliant with HJ/T 46 requirements for flue gas flow conditioning.
- Onboard non-volatile memory plus SD card and USB host support—enables unlimited data logging with timestamped, GPS-tagged (optional), and audit-ready file structure.
- Multi-power architecture: AC 220 V ±10% / 50 Hz mains operation with battery backup; DC 24 V input/output ports for external peripherals; overvoltage protection (> AC 250 V) and intelligent power-loss recovery.
- Predefined stack database with Chinese-character input capability—stores historical configuration profiles (duct geometry, velocity traverse points, probe type) for rapid re-deployment.
Sample Compatibility & Compliance
The ZR-3260B is validated for use across coal-fired boilers, cement kilns, waste incinerators, glass furnaces, and metallurgical smelters. It accommodates optional modular accessories including: a dedicated cooking fume sampling probe (per HJ 629-2011), asphalt fume probe, capacitive humidity sensor module (replacing dry/wet bulb assembly), and flue gas pre-conditioner (for particulate removal and water vapor reduction prior to gas analysis). Certified by the China Environmental Protection Product Certification Center (CEPPC) and independently verified by the Ministry of Ecology and Environment’s Environmental Monitoring Instrument Quality Supervision & Inspection Center (Report No. Z(R)2018-154), the analyzer meets metrological verification requirements per JJG 968-2002 (flue gas analyzers), JJG 680-2007 (particulate samplers), and JJG 518-1998 (Pitot tube calibration). Its design aligns with GLP-aligned field data integrity principles, supporting traceable calibration logs and operator ID tagging.
Software & Data Management
Data acquisition and reporting conform to HJ 75-2017 (Continuous Emission Monitoring System Technical Requirements) for QA/QC traceability. The embedded firmware supports automated calculation of oxygen-referenced concentrations, excess air ratio (λ), standard dry flow rate, and pollutant mass emissions. Export formats include CSV and PDF reports compliant with provincial environmental monitoring station templates. Bluetooth 5.0 enables wireless synchronization with the official Junray FieldLink mobile application (iOS/Android), permitting remote start/stop, real-time parameter viewing, and firmware updates. Optional cloud upload (via LTE module) facilitates centralized fleet management and regulatory submission workflows. All stored datasets include immutable metadata: operator ID, GPS coordinates (if enabled), calibration certificate IDs, and instrument serial number—supporting 21 CFR Part 11–compatible audit trails when deployed in regulated compliance environments.
Applications
- Regulatory stack testing for SO₂, NOₓ, CO, O₂, and PM in thermal power plants and industrial boilers (per HJ/T 397-2007).
- Performance evaluation of FGD (flue gas desulfurization) and ESP/Fabric Filter systems—including efficiency calculation via inlet/outlet paired measurements.
- Method validation and field calibration of CEMS (Continuous Emission Monitoring Systems) per HJ 75-2017 Annex D.
- Source apportionment studies requiring synchronized particulate mass + speciated gas data under variable load conditions.
- Environmental impact assessments (EIA) and permit renewal audits requiring full-stack parametric profiling (T, P, v, XH₂O, Qstd,dry).
- Mobile ambient air quality surveys where portability, battery autonomy (>4 h continuous operation), and ruggedized housing are critical.
FAQ
Does the ZR-3260B support direct particulate mass concentration readout without lab gravimetry?
Yes—when equipped with optional β-ray absorption or TEOM (Tapered Element Oscillating Microbalance) modules, it provides real-time PM concentration output compliant with HJ 836-2017.
Is the instrument suitable for explosive atmospheres?
No—it is rated for non-explosion-proof environments only. ATEX or IECEx certification is not available.
Can humidity be measured without external power or compressed air?
Yes—the capacitive humidity probe option operates passively and requires no auxiliary gas supply or vacuum source.
What is the maximum allowable flue gas temperature during sampling?
The standard probe supports continuous operation up to 200 °C; high-temperature probe variants (up to 400 °C) are available as custom configurations.
How is data integrity ensured during extended field deployments?
All measurements are time-stamped with internal RTC, logged with operator authentication, and protected against overwrite until manually archived—meeting minimum GLP field data retention requirements.
