    The samples for analysis should be taken at the boiler exit, at the entries and exits of the auxiliary plant (i.e. economizer and/or air heater) if fitted; and certainly at the nearest predictable point to the fuel bed. It is usually assumed that if the CO 2, CO, and O 2 quantities are measured and the balance to 100 percent taken as nitrogen, then the analysis is complete.Learn More
