| DGA-X |
|
|
DGA-X is a continues emission monitoring system designed to quantify and analyze environmental gases like SO2 and NO being emitted from industrial stacks. Using a UV light source DGA-X efficiently detect emission within UV domain. It utilizes an In-Situ type probe placed inside a stack to measure the density of gas passing it, which requires no sampling.
DGA-X is composed with a probe and a controller unit. The probe can be broken down into a number segments and they are a gas passage, windows, a mirror fixture, an optical sensor, an optical fiber assembly, and an air-purge. The controller unit also can be broken down into a number of modules and they are a light source, an optical sensor, a Monochromator, a signal processes unit, an output unit, and a power supply unit. DGA-X probe can be customized for Power Plants, Waste Treatment Plants, Steel Industry, Cement Industry, Pulp Industry, and Petrochemical Industry. |
| Benefits |
- In-situ measuring system Instantaneous monitor from aa direct gas duct. No need for gas extraction and preparation.
- One device supports both SOx and NOx reduces maintenance costs.
- DOAS approach maintains high level of accuracy filtering out dusts, humidity, and other undesired gas components.
- No need of external transceiver/receiver unit or computer system for monitoring. |
| Specification |
- Lamp: a deuterium lamp having UV spectral range between 200~250 nm is used in the light source unit. Benefits are long service life, high stability, and Intensified signal output.
