Online Infrared flue gas analyzer GASBOARD-3000

Product catalog summary

Measurement Methods
The Gasboard 3000 utilizes proprietary infrared NDIR detectors for measuring CO, NO, and SO2 in ppm ranges and CO2 in percentage volume ranges. An electrochemical detector is used for O2 measurement, with an optional paramagnetic sensor available. A catalytic converter is employed for NOx measurement by converting NO2 to NO.

General Features
The analyzer features micro-flow NDIR gas sensor technology, unaffected by gaseous water or sampling flow rate fluctuations. It provides accurate low concentration gas measurements, includes a built-in zeroing pump, and offers RS232 and 4-20mA outputs. The device has a large LCD display and a keyboard interface for setup and calibration, along with a flow meter for gas flow regulation.

Applications
The Gasboard 3000 is suitable for monitoring boiler and furnace exhaust emissions, cement production line processes, and continuous emission monitoring systems (CEMS).

Measurement Range and Accuracy
The analyzer measures NO, CO, and SO2 from 0-5000 PPM with a resolution of 1 PPM and CO2 from 0-100% with a resolution of 0.01%. The accuracy is ±2% with a T90 response time of less than 10 seconds. O2 measurement ranges from 0-100% with a resolution of 0.01% and accuracy of ±2% to ±3% depending on the sensor type.

Technical Specifications
The device is housed in a 19’’ - 3U rack enclosure, weighing approximately 12 kg. It operates on 220VAC/50Hz or 115VAC/60Hz power supply. It features a 320x240 LCD display, 4-20mA analogue output, RS232 communication, and digital relays for gas alarms. The gas sampling system includes an external pump, with nominal gas flow rates of 0.7 to 1.2L/minute.

Operating Conditions
The analyzer operates within a temperature range of 0-50°C and relative humidity of up to 95% RH. It requires dry gas free of oil and dust particles, with ambient pressure between 86-108 kPa.

Typical Applications
Applications include safety monitoring in coal milling, efficient control in cement production, and environmental monitoring in CEMS.

Gas Conditioning System
The system includes components like a gas cooler, compressed chiller, sampling pump, water condenser, peristaltic pump, and electromagnetic valve.

Advantages
The Gasboard 3000 addresses interference from water vapor on SO2 and NO measurements using micro-flow infrared sensors and a special compensation mechanism. It also employs temperature correction methods to mitigate environmental influences on measurement stability.

Why should be Gasboard 3000 ? 1. How to solve the inference from water vapor to SO2 and NO? The traditional double-beam infrared gas sensor technology due to the impact of filter bandwidth, SO2, NO and water vapor IR absorption peaks overlap, cross-infection is very serious. Experimental results show: 4 ℃ in the flue gas water vapor saturation SO2, NO measurement results of up to 50-100ppm. Infrared gas sensors using micro-flow, while the water allocation of special compensation mechanism, to a large extent resolved gaseous water on SO2, NO interference problems, after testing and validation,...
