The work of preparing International Standards is normally carried out through ISO techni

10、cal committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely w

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria neede

16、on of solid fuels, O 2is consumed and CO 2is simultaneously produced. Biogenic and fossil organic matter do not only show strong differences regarding O 2consumption and CO 2production, but also differences in their respective calorific value and carbon content are observable. The balance method can

17、 be used when the elementary composition of moisture and ash free biomass and fossil matter present in the fuel used is known and online stack gas composition measurements (O 2and CO 2 ) are available at high accuracy. It will enable online modelling of biomass fossil ratios in stack gas giving the

18、user the opportunity to control or report that ratio. The generated model data can be verified using the radiocarbon ( 14 C) determined biomass fuel ratio. The results obtained using this document will be complementary to the results obtained with ISO 13833. In ISO 13833, the biogenic fraction in st

19、ack gas from plants with unknown fuel composition is determined using the 14 C method. If the chemical composition of pure biogenic and fossil matter (contents of C, H, N, S, O referred of moisture and ash free biomass and fossil organic matter, respectively) present in the fuel used is known, the b

20、iogenic CO 2fraction can be calculated utilizing different operating data of the Waste for Energy (WfE) plant. When the chlorine content is sufficiently high, it can be additionally used to optimize the mass balances. ISO 2016 All rights reserved v Stationary source emissions Determination of the bi

21、ogenic fraction in CO 2in stack gas using the balance method 1 Scope This document enables the determination of the biogenic fraction in CO 2in 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) pla
