BS ISO 18466:2016 pdf download.Stationary source emissions — Determination of the biogenic fraction in CO 2 in stack gas using the balance method
1 Scope
This document enables the determination of the biogenic fraction in CO 2 in stack gas using the balance method. The balance method uses a mathematical model that is based on different operating data of the Waste for Energy (WfE) plant (including stack gas composition) and information about the elementary composition of biogenic and fossil matter present in the fuel used.
NOTE Use only mixed fuels when using the calculation method.

3.1 biogenic
produced in natural processes by living organisms but not fossilized or derived from fossil resources
3.2 biomass
material of biological origin excluding material embedded in geological formation or transformed to fossil
3.3 radiocarbon
radioactive isotope of the element carbon, 14 C, having 8 neutrons, 6 protons, and 6 electrons
3.4 sample
quantity of material, representative of a larger quantity for which the property is to be determined
7.2.2 Amount of combustion air
The amount of air used for combustion is determined using a calculation including the measured flue gas flow and the combustion products (this is more precise than the regular measurement data available). For an average combustion air temperature (15 °C) and average relative humidity (70 %), the relationship between combustion air and flue gas flow is the following: Wet combustion air flow = 1,035 times the dry flue gas flow.
