Abstract

The invention provides a carbon-14 testing sample bottle and test method and a sampling and sample preparation system for a mixed combustion ratio of a coal-mixed biomass power station. The carbon-14testing sample bottle and test method and the sampling and sample preparation system can help overcome lack of effective monitoring means for the mixed combustion of a conventional coal-mixed biomasscombustion power station and monitor a biomass mixed combustion ratio of a coal-mixed biomass combustion power station, and data is provided for biomass mixed combustion monitoring and subsidy-relatedwork. Compared with conventional methods, the carbon-14 testing sample bottle and test method and the sampling and sample preparation system are advantageous in that short detection period can be realized when the biomass mixed combustion ratio is low, accuracy of detection results can be improved, and the coal-mixed biomass combustion power plant is integrated with a mixed combustion ratio monitoring station.

Description

technical field [0001] The invention relates to the technical field of detection methods, in particular to a sample bottle for carbon-14 testing, a testing method and a sampling and sample preparation system for the mixing ratio of a coal-mixed biomass power station. [0002] technical background [0003] At present, coal is still the main energy source in the power industry. With the development of society and the continuous improvement of economic level, people's demand for electricity has increased sharply, while coal reserves have declined sharply, it has also caused great damage to the natural environment. Biomass energy is a carbon-containing renewable energy. Its "carbon neutral" characteristics make it possible to use biomass energy to replace some fossil energy represented by coal, reduce CO2 emissions and alleviate the greenhouse effect. [0004] Biomass blended coal combustion is an excellent way to use biomass energy on a large scale. It can not only reduce pollut...
