Abstract: A sampling and preparation system is positioned in a coal and biomass co-fired power station, which includes a sampling pipe connected with a boiler flue of the co-fired power station. The sampling pipe from the end close to the boiler flue to the other end away from the boiler flue includes a filtering device, a mass flow controller, a carbon dioxide trap and a pumping device. The sampling and preparation system also includes a carbon dioxide transfer device and a 14C testing device. The carbon dioxide transfer device is applied to transferring the carbon dioxide from the carbon dioxide trap to the 14C testing device which is applied to measuring the 14C in the carbon dioxide sample. The system may calculate the biomass blending ratio of the coal and biomass co-fired power station rapidly.

Abstract: A 14C testing bottle, a 14C testing device, a 14C testing method, a sampling and preparation system and its implementation method are provided. The 14C testing bottle includes a pressure-bearing shell and a sample bin positioned in the pressure-bearing shell. A cavity is arranged in the sample bin and the 14C testing bottle is provided with an injection port connected to the cavity. The sample bin may diffuse the light produced in the cavity and at least part of the sample bin is transparent. An optical fiber channel is set on the pressure-bearing shell. One end of the optical fiber channel is connected with an external scintillation counter, and the other end of the optical fiber channel is connected with the transparent part of the sample bin. The 14C testing bottle may measure the 14C content in the carbon dioxide sample rapidly.
