Combustion Efficiency Optimization Manual for Operators of ...

Boiler maintenance should focus on every problem that may degrade boiler performance: e.g. an increase in the temperature flow rate or combustible content of the flue gas; an increase in convective or radiant heat losses from the shell ductwork or piping; or an increase in blow-down requirements.

Flue gas flow rate measurement errors. Interim report ...

Jun 01 1996 · The CEMS flue gas flow rate monitor is suspected to be one of the factors contributing to this high bias. Since the flue gas flow rate monitors are certified and calibrated using EPA Methods 1 and 2 there is concern that the bias is not from the monitor directly but rather from the Methods 1 and 2 procedures.
