I. Introduction
SS-UV-300 flue gas analyzer (low emission monitoring) based on years of experience in research and development of flue gas analyzer, combined with the field practice of nearly ten thousand successful application cases. A number of techniques of the flue gas analyzer (standard form) are upgraded (many times return room to increase gas absorption optical path, and higher accuracy of spectrometer, convection heat transfer core module temperature control, etc.).
The analyzer is based on DOAS and chemometric algorithms (PLS), able to measure concentration of gases including SO2, NO2, NO, O2, NH3, Cl2, O3, H2S, CH3I, etc. It has features of high measure accuracy, outstanding reliability, fast response time and wide applicable scope. All indexes reach or exceed those of domestic & foreign similar products, and fully qualify measurement technology index of low emission monitoring occasions.
II. Application fields
It mainly used for industrial boilers, industrial furnaces emissions monitoring in power plant, iron & steel factory, cement plant and son.
