Control-Analytical - Model ESE-1000 -Continuous Flue Gas Emission Monitoring System
The ESE-1000 continuous flue gas emission monitoring system (dilution method CEMS) incorporates a dilution extractive methodology. This advanced solution employs ultraviolet fluorescence detection, chemiluminescence analysis, and zirconium oxide oxidation mechanisms to quantify SO2, NO?, and O2 concentrations. Optionally, the system simultaneously determines CO and CO2 levels through supplementary measurement protocols.
Furthermore, the system facilitates wired or wireless transmission of standardized datasets to enterprise-level monitoring hubs and regulatory compliance portals. This comprehensive approach enables real-time monitoring and optimization of industrial emission control systems while ensuring strict adherence to environmental protection mandates.

The dilution extractive Continuous Emission Monitoring System (CEMS) incorporates proprietary on-site sample conditioning and gas acquisition technology. During the initial collection phase, a supersonic orifice within the sampling probe initiates precise gas extraction. Subsequently, the system combines dry instrument air with extracted flue gas through controlled pneumatic blending.This innovative dilution methodology achieves substantial dew point depression through predetermined concentration gradients (typically 25:1 to 250:1). Consequently, the resultant gas mixture maintains thermodynamic stability below site-specific ambient temperature thresholds. The integrated approach obviates conventional moisture removal requirements prior to analytical instrumentation.
Furthermore, the optimized vapor pressure characteristics prevent interstitial condensation formation across operational temperature ranges. Even after dilution, the sample remains a wet gas, preserving its original moisture content. Thus, the measurement process is classified as a “wet-based measurement,” ensuring accurate analysis without the need for further conditioning.
Subsequently, a compressed air treatment assembly purifies, filters particulate matter, and dehumidifies the dilution medium until achieving a dew point below -30°C. Following air preparation, the system dynamically combines flue gas with prepared dilution air at a predetermined ratio through a critical orifice’s calibrated restriction.
Finally, the homogenized mixture flows through dedicated sample lines to a centralized distribution hub, where multiple analytical devices simultaneously access the standardized gaseous medium. This modular configuration optimizes operational flexibility by enabling parallel instrument sampling while maintaining consistent analytical parameters across measurement platforms.
Consequently, the architecture enhances system reliability through redundant sampling capabilities and coordinated data acquisition protocols.
