METHOD FOR TIME DETERMINATION AND MONITORING OF BIOGENIC AND FOSSIL MASS CONTENT OF HETEROGENEOUS FUEL FROM CARBON ANALYSIS 14 POST-COMBUSTION OF COMBUSTION GAS CO2.

摘要

Method of determining and followed in the time of the content by mass biogenic fossil fuel and of a heterogeneous on the basis of the analysis the carbon 14 post - combustion of the co2 of combustion gases. The method comprises a sampling system which is proportional to the co2 (1) of the analyses c14 ex - situ of the co2 removed, making it possible to determine the ratio between the carbon biogenic and fossil fuel (2). These elements are coupled to the continuous measurement of the moisture content in the duct (3) and to the regular sampling of the combustion residues: (4) (5) which are tested ex - situ (6) in order to determine their degree of humidity and inert. A computation algorithm (7) makes it possible to determine the mass of water, the inert material, of material biogenic and fossil material of the fuel. The process according to the invention is particularly intended for the characterization of the combustible mass of heterogeneous input of energy production installations.
