Online Stack Gas Analyzer
Online Stack Gas Analyzer
Vasthi online monitoring stack gas analyzer (OMGA-2000 UV) is an one-site installation stack gas analyzer which is developed after years reaching and design on online gas analysis instruments. It can monitor gas parameters, including concentration of SO2, NOx, O2, dust, humidity, temperature, pressure, flow and etc. Vasthi online monitoring stack gas analyzer is mainly applied to tail gas emission monitoring process analysis in many fields including coal-fired power plant, waster-to-energy plant, cement factory, glass factory, lime factory, ceramics factory, sinter, coke oven, DeSOx process and DeNOx process.
Vasthi online monitoring stack gas analyzer adopts 150˚C high temperature heat tracing for whole process, on-site filtering and sampling, on-site analysis and measuring technology. All paths contacting with gas are made of 316L stainless steel. This gas analyzer has many transcendent features, such as low detection limit, accurate measuring result, easy to calibrate and compare with simple construction and without any moving parts.
FEATURES
MODEL NO : OMGA-2000UV
- OMGA-2000 UV adopts DOAS and PLS which is the hard hitting online analysis technology for measuring SO2, NOx and other gases, with low detection limit 0.1ppm;
- Uses pulsed xenon lamp as light source with 10^9-time service life; high stability; no pre-heating time;
- Is with no light-cutting, interferometer or other optical moving parts; high reliability; on-site Vibration will have no damage to analyzer and no impact on measured value;
- Directly detects NO and N0z to obtain N0x without N02—ONO converter;
- User modularization design of light source, spectrometer, HMI module, gas chamber, interface module and etc. j with high reliability and extensibility; easy to maintain;.
- Splits light by holographic grating; detects by dode array; finally gets complete successive absorption spectrum; is with high resolution; guarantees low detection limit, low temperature drift and fast response time.
