Analizzatore di indice di combustione – IGCA
General description:
The IGCA (Industrial Gas Combustible Analyzer) measures the quality of all combustion gases (natural gas, biogas, coke oven gas, recovery gas, etc.) by determining the following characteristics:
- Wobbe Index
- CARI Index
- High and Low heating values (HV version)
- Density (HV version)
Techical description:
The measuring principle consists in mixing a known concentration of oxygen with the combustible gas. Everything is then burned (catalytic combustion) and then sent to a zirconium oxide cell. The residual oxygen, after calculation, brings to the Wobbe index and the CARI index.
The device is divided into several parts:
- An air / gas mixer
- A catalytic combustion chamber
- A cell for measuring oxygen
A control electronics manages all the measurement and safety information and provides a continuous measurement of the CARI and Wobbe indexes. The controller also allows for automatic calibrations with calibration-related malfunction detection.
