Application Scenarios

In a coal-fired power plant’s flue gas duct, the raw gas is at 150°C, saturated with water vapor, and laden with fly ash and acidic compounds. Directly feeding this stream to a zirconia oxygen analyzer or an NDIR gas analyzer for SO₂/NOx measurement would cause immediate instrument failure and yield useless data. The ABB SCC-F 23212-0-110310 Sample Gas Feed Unit​ is installed as the critical interface. A heated sample probe extracts gas from the duct. The sample is then routed to the SCC-F​ unit. Here, it first passes through a primary filter to remove particulates. A powerful Peltier cooler then chills the gas to 2-5°C, condensing out the water vapor (which is automatically drained). The cool, dry gas passes through a final fine filter and a precision pressure regulator before a mass flow controller delivers it at a constant, optimized flow rate to the analyzer cabinet. The SCC-F 23212-0-110310​ directly addresses the core pain points of analyzer protection, measurement accuracy, and system maintenance by ensuring the analyzer receives only a “laboratory-quality” sample, representative of the process but free of destructive components.

Technical Principles and Innovative Values

The ABB SCC-F 23212-0-110310​ is engineered as a cohesive system where each component’s performance is optimized in relation to the others, applying core principles of sample conditioning to solve the “last meter” problem in analytical measurement.

Innovation Point 1: Co-Engineered Cooling and Filtration for Maximum Moisture Removal.​ The unit’s design synchronizes the Peltier cooler’s operation with the filtration stages. The gas is cooled afterinitial coarse filtration, preventing wet particulates from forming a mud-like paste on the cooler block. The chilled gas then passes through a hydrophobic coalescing filter that captures the newly formed fine water aerosols. This sequenced approach—filter, then cool, then filter again—is far more effective at delivering a truly dry gas than cooling alone. The condensate removal system uses a sensor-less, pneumatic pumping principle based on level detection, ensuring reliable drainage without complex floats that can foul.
