The invention discloses a
coal-fired power
plant carbon emission on-line monitoring method based on
laser induced breakdown
spectroscopy. The
coal-fired power
plant carbon emission on-line monitoringmethod based on the
laser induced breakdown
spectroscopy comprises the following steps: S1, obtaining known data of a power
plant; S2, using the LIBS method to continuously measure the carbon contentof
coal, the carbon content of
fly ash and the carbon content of
slag; S3, calculating the carbon
oxidation rate of coal
combustion; and S4, calculating the carbon emission rate and total carbon emissions of the power plant. The invention utilizes the LIBS method to measure the carbon content of coal, the carbon content of
fly ash and the carbon content of
slag on line to calculate the carbon
oxidation rate of coal
combustion, so as to obtain the carbon emission rate and the total carbon emissions of the coal-fired power plant according to a carbon balance calculation formula. The coal-fired power plant carbon emission on-line monitoring method based on the
laser induced breakdown
spectroscopy combines the LIBS detection method with the carbon balance method, which can realize continuous online measurement, and has the advantages that the analysis speed is high, the sensitivity is high, the preparation of samples is not required, uneven samples can be analyzed,
remote detection can beperformed and the like; meanwhile, more accurate and reliable real-time carbon emission data can be obtained online, which lays a foundation for
carbon dioxide emission reduction.
