biogascarbonnitrogenratios

Overview

Engineering reference data for Biogas Carbon Nitrogen Ratios in combustion engineering.

Key Formulas

Heat Release

Q=m˙HVQ = \dot{m} \cdot HV

Fuel energy release rate.

Air-Fuel Ratio

AF=mairmfuelAF = \frac{m_{air}}{m_{fuel}}

Mass of air per mass of fuel.

Excess Air

EA=O221O2×100%EA = \frac{O_2}{21 - O_2} \times 100\%

From flue gas oxygen measurement.
