CO₂ Monitoring System for Power Plants Based on the Thermal and Humid Sampling Method

To address flue gas component loss and low accuracy in traditional dry sampling for power plants, a hot-wet sampling-based CO₂ information monitoring scheme is proposed. It elaborates the system′s core principles, overall structure, key device design, data transmission/processing, precision calculation units and implementation plans. Prototype tests verify that the system has superior stability and accuracy to traditional ones, enabling accurate acquisition of power plant carbon emission data and supporting carbon emission management.
