Air Emission Boiler Reference Value

ACP - Dynamic projection of anthropogenic emissions

End-of-pipe control measures are more effective for reducing air pollutant emissions before 2030, while low-carbon policy will play a more important role in continuous emission reduction until 2050. In contrast, China's emissions will remain at a high level until 2050 under a reference scenario without active actions (i.e. SSP3-70-BAU).

Forbes Marshall | EnconTips - Reference boiler

The Net Calorific Value (NCV) of a fuel is defined on the basis that all of the water vapor produced by combustion of fuel remains in the vapor state. Enthalpy loss – i.e. the loss in boiler efficiency due to converting the inherent moisture in fuel to vapor is not captured when the NCV is used calculate the boiler

Practical Issues in Combustion O2 Measurement

For example, the quality of the reference air is just as important as the quality of the calibration gas. A variable reference gas concentration, such as might be caused by humidity, effects the oxygen measurement directly. Reasonable changes in the reference air humidity can change the process oxygen reading by 0.75% O 2. It is a variable
