CEMS for Cement Plants

This continuous emission monitoring system (CEMS) for cement plants measures sulphur dioxide (SO2), nitrogen dioxide (NO2) and total particulate matter (PM) in stack gas. It is built from extractive gas analysers, in-situ gas analysers and a particulate in-situ analyser, selected to suit the source. Results are collected by a data acquisition system (DAS) and passed through a data interface system (DIS) to the DOE / EPA server, so emissions can be checked continuously against the limit values that apply to cement kilns, glass furnaces, rotary furnaces and ceramic furnaces.

Features

• One system covering SO2, NO2 and total PM / dust
• Extractive and in-situ gas analysers, plus a particulate in-situ analyser
• Data acquisition system (DAS) and data interface system (DIS) for reporting
• Sized for cement kilns of all sizes, glass furnaces (≥ 1 ton/day), rotary furnaces (≥ 1 ton/day) and ceramic furnaces (> 10 ton/day)

How it works

• SO2, extractive: NDIR, NDUV, GFC, FTIR, PAS or fluorescence
• SO2, in-situ: DOAS, GFC or FTIR
• NO2, extractive: NDUV, PAS or fluorescence
• NO2, in-situ: DOAS
• Total PM / dust, extractive: light scatter or beta absorption
• Total PM / dust, in-situ: transmissometry or triboelectric, double pass or single pass

Emission limit values

• Cement kiln (all sizes): NO2 800 mg/m³, total PM 50 mg/m³
• Glass furnaces: SO2 800 mg/m³, NO2 800 mg/m³, total PM 50 mg/m³
• Rotary furnaces for hard quicklime or sintering dolomite: NO2 1500 mg/m³, total PM 50 mg/m³
• Ceramic furnaces: total PM 50 mg/m³ where the dust load emitted is ≥ 2.0 kg/hour

DOE / EPA requirements

• Supplier listed as an appointed and approved company on the DOE / EPA website
• TUV / MCERT certificate
• Data acquisition system (DAS) and data interface system (DIS)

Applications

• Cement kilns
• Glass furnaces, including glass fibre
• Rotary furnaces for quicklime and dolomite
• Ceramic furnaces for tiles, bricks, refractories, stoneware and porcelain
