Continuous Emission Monitoring System CEMS
Continuous Emission Monitoring System
Pls visit our web:
CEMS has four basic parts: the dust monitoring subsystem, gaseous pollutants monitoring subsystem, flue gas parameter monitoring subsystem, system control and data acquisition and processing subsystem. It can monitor SO2, NOx, O2, dust, temperature, pressure, flow rate and other parameters such as HCl, HF, CO, CO2 for specific occasions. After dedusting by sampling probe, sampling by heating pipe, dehydration and cooling by two-step condensing, the measured gas is analyzed by the heated gas analysis module (TDLAS and DOAS technique).It is an effective solution to solve the technical problem that great humidity variation of the waste incineration and other occasions lead to measuring data fluctuation.

Features
l All the indexes are measured in the condition of high temperature
ü To avoid condensation water absorbing SO2 which may lead to low measurement results, and corrosion of pre-treatment pipeline .
l System has simple structure, high integration
ü Under the effect of drainage pump, the flue gas passes through probe, heat tracing pipeline; directly goes into the gas chamber; SO2 and NOx concentrations are being measured; the flue gas enters the zirconia/humidity/drainage pump module, and then discharges directly.
ü System has simple structure, high integration and easy to maintain.
l Achieve the simultaneous measurement for NO and NO2
ü Carry out simultaneous measurement for NO and NO2, and then obtain NOx by the accumulation method. No need of NO2→NO converter.
l Self-researched and developed core devices and algorithms
ü Core devices are self-researched and developed, including the light source, spectrometer, gas chamber, humidity module, dust meter, etc.
ü DOAS algorithm is self-researched; the system has strong market competitiveness.
Applications
This product can be widely applied in the following:
- Flue gas continuous emission monitoring ( CEMS ) for the power plants (analyze SO2, NO, NO2 and O2 )
- DeSOx process monitoring (analyze SO2 and O2)
- DeNOx process monitoring (analyze NO, NO2, NH3 and O2)
- Waste incineration flue gas continuous emission monitoring (analyze SO2, NO, NO2 and O2)
