High Temperature UV Flue Gas Monitoring System
OVERVIEW
High Temperature UV Flue Gas Monitoring System Gasboard-9070 is
based on advanced UV-DOAS gas analysis technology, which can
simultaneously measure the concentration of SO2, NO, NH3 and other
gases. It adopts multiple reflection chamber to reach a lower limit
of detection. The system adopts high temperature tracing on whole
sampling circuit to ensure high measurement accuracy, that can be
widely used to monitor the flue gas from industrial stacks or
stationary pollution source before and after desulfurization and
denitrification, and accurately reflect the conditions of ammonia
escaping.
FEATURES
• Adopt UV-DOAS technology to measure SO2, NO, NH3 gas
concentration simultaneously with high accuracy.
• Using multiple reflection gas chamber to provide ultra-low range
measurement and low detection limit.
• High temperature tracing on entire gas flow path, adopting
low-adsorption materials and processing techniques to effectively
avoid the loss of SO2 and NH3.
• Extractive measurement method, not affected by dust, temperature,
and pressure fluctuations in the flue.
• Built-in automatic correction algorithm to eliminate interference
from other gas components.
• Automatic calibration design, easy for operation and maintenance.
• Widely applicable on different applications, not restricted by
on-site installation conditions.
