COSA 9750

Wobbe Index / Calorific Value / CARI

The Cosa 9750 is a fast response Zero Emission calorimeter for the on-line monitoring of Wobbe Index (WI), Combustion Air Requirement Index (CARI) and Heating Value (HV). The COSA 9750 is based on the Residual Oxygen Method (ROM), thus avoiding the use of a flame.

The analyzer is immune to ambient temperature fluctuations and can be installed outdoors or in harsh environments.The high furnace temperature of 1050°C, converts all sulfur constituents into SO2, thus eliminating corrosion issues with the exhaust gas. Optionally, the oxygen concentration in the sample can be measured continuously and the residual oxygen is offset accordingly. Further options include simultaneous measurements of sulfur and hydrogen concentrations.
