Thermal power generating unit carbon emission accounting method based on field monitoring data

Abstract

The invention provides a thermal power generating unit carbon emission accounting method based on field monitoring data. The method comprises the following steps of 1, selecting monitoring points; 2,installing a CO2 measuring instrument at a thermal power generating unit chimney outlet; 2, collecting monitoring data, wherein the monitoring data monitored by a CEMS and the CO2 measuring instrumentwhich are arranged at the chimney outlet is transmitted to a main station after being collected by a data collection module, and is stored by the main station; 3, calculating the CO2 emission amountper hour, wherein one hour serves as a calculating cycle, the monitoring data collected within one hour serves as the basis, the halting data and ultralimit data in the data are removed, and then theCO2 emission amount per hour is calculated; 4, counting the CO2 emission amount, wherein the CO2 emission amount of the unit hour serves as the basis, and the summarizing value of the CO2 emission amount is obtained through a summing operation; 5, calculating the strength of CO2 emission, wherein the unit CO2 emission strength means the CO2 emission amount every time when the unit generates one kilowatt hour, namely the ratio of the CO2 emission amount within the duration to the power generation amount within the duration.

Description

technical field [0001] The invention relates to a carbon emission accounting method for a thermal power unit based on on-site monitoring data. Background technique [0002] Among all greenhouse gases, carbon dioxide is one of the main gases causing global climate change. According to statistics, the impact of carbon dioxide on global warming is about 55%. The power industry has always been the main source of carbon dioxide emissions due to the thermal coal combustion process. According to the "2010 and "Eleventh Five-Year" Power Industry Energy Conservation and Emission Reduction Report" issued by the Electricity Regulatory Commission, the national power industry's carbon dioxide emissions in 2010 About 50% of the country. [0003] As a major economic province in the country, Jiangsu is also a major province of greenhouse gas emissions. As many as 400 key emitters have been included in the carbon emissions trading market, ranking among the top in the country. In order to ...
