Principle

1.Gaseous pollutant monitoring sub-system: Direct extracting mode (heating pipeline method);

2.Gas components: O₂, SO₂, NO_x concentration (Non-disperisive infrared spectrometry);

3.Smoke monitoring sub-system: forward scattering mode;

4.Smoke parameter measuring sub-system;

Gas flow: Differential pressure method

Flue-gas temperature: platinum resistor

Flue-gas pressure: static pressure method

Flue-gas humidity: humidity measuring mode
