EmailGA-5000 Continuous Emission Monitoring System(On-site) is composed by dust monitoring subsystem, gaseous pollutant monitoring subsystem, flue gas parameter monitoring subsystem, and system control & data acquisition & processing subsystem. It can monitor SO2, NOX, O2, dust, temperature, pressure, velocity, etc. Other parameters can be extended as required for special occasions, such as HCl, HF, CO, CO2, humidity, etc. After passing by sampling probe for dust removal, measured gas directly enters high-temperature gas analysis module (DOAS technology) for analysis and measurement. Without tracing pipe and condenser, it not only owns response but can effectively solve the technical problem that moisture absorbs SO2 and cause low measuring result in Condensation Method, having prominent advantage especially in field of low concentration measurement.
Features
Adopt UV-DOAS and stoichiometric algorithm, detection limit can reach 1mg/m3.
Employ holographic grating for light splitting and diode array for detection to obtain continuous and complete absorption spectrum; high resolution, ensuring low detection limit, small temperature drift and fast response.
No condensation process, avoid condensate water absorbing SO2 and cause low measuring result; reflecting actual working condition.
Without heat tracing pipe, fast response and low cost.
Compared with extraction method, it owns advantages of high measuring accuracy & reliability, low investment costs, fast response time, etc.
Compared with in-situ method, it owns advantages of online calibration, small measuring value fluctuation, high reliability, easy maintenance, etc.
Application
Applied in exhaust emission monitoring and process control in coal-fired power plant, garbage power plant, cement plant, glass plant, lime factory, ceramics factory, sintering process, coke oven, desulfurization technology, denitration technology, etc.
