Continuous Emissions Monitoring Systems (CEMS)

   Continuous emission monitoring system (CEMS) is the total equipment necessary for the determination of a gas or particulate matter concentration or emission rate using pollutant analyzer measurements and a conversion equation, graph, or computer program to produce results in units of the applicable emission  and transmit the information to the competent 

we provide CEMS system to monitoring : SO2/NOX/CO/CO2/HCL/HF/ dust/flue gas flow rate/pressure/temperature .more information pls visit www.gasese.com

Ammonia Slip Analyzer

Ammonia Slip Analyzer

SCR’S and SNCR’s reduce NOX emission by injecting ammonia into the combustion flue gas ,which ideally reacts with the NOX to form H2O and N2.The efficiency of the SCR/SNCR is determined by monitoring the outlet for excess NH3,referred to as NH3 slip .

The SNCR process requires the introduction and mix of Ammonnia or urea with flue gases in a hotter environment with a temperature optimized to between 800-900℃,Temperature control is important in the process,as low temperatures can cause a surplus of unreacted NH3

Extractive surrogate measurements will continue to dominate the utility market for now because of the ease of acceptability as part of a CEMS.Tunable Diode laser technology is proving to be the most accurate method.

HCL gas monitoring in Waste Incineration plant

HCL gas monitoring in Waste Incineration power plant

1. Waste Incineration power plant: HCL gas monitoring system was installed on the stack on the 40 meters high from the ground. The sampling system adopted hot & wet sampling and gas pretreatment system, and sampling distance is less than 5 meters. The measurement range of HCL is 0-30ppm.

2. eLAS-300 TDLAS HCL Gas Analysis System  uses high temperature heating extracting technology for continuous online monitoring of HCL in the sample gas. The system consists of sampling and transmission unit , pretreatment and control unit , analysis unit. 

3. HCL reading on the site

4. The third party testing:The third party testing machine: Gasmet  FT-IR gas analyser, with hot wet sampling system;Sampling from the similar sampling point of CEMS system, via heated tube down to gas analyzer transport car

The diagram trends were almost the same between CEMS SO2  and eLas-300  HCL  value, especially after 15p.m., the reading trends were going the same
