Embodiment Construction

[0043] like figure 1 As shown, the accurate measurement method of the carbon emission of the coal-fired power plant of the present invention is used to measure the consumption of the coal-fired power plant in the coal-fired life cycle. The set consumption is W coal The carbon emissions produced by raw coal W g , the precise measurement method selects the stage before coal combustion, the stage of coal combustion and the stage after coal combustion as the carbon emission W g The measurement range of , in which, in the pre-combustion stage, the coal-fired power plant obtains the consumption W through coal mining, coal preparation, coal washing and coal transportation coal raw coal, in the coal-fired combustion stage, the coal-fired power plant will consume W coal The raw coal is burned to produce electric energy with a power generation of E and a corresponding amount of flue gas. In the post-coal combustion stage, the coal-fired power plant performs desulfurization, denitrific...

Abstract

The invention discloses a method for accurate measurement of carbon emission from a coal-fired power plant. The method is used for measuring the carbon emission Wg generated from raw coal in preset consumption Wcoal consumed in a fire coal life cycle by the coal-fired power plant, and comprises the following steps: step S10, measuring the carbon emission W3 produced in the early combustion stage of the fire coal from the coal-fired power plant; step S20, measuring the carbon emission Wgr generated in the middle combustion stage of the fire coal from the coal-fired power plant; step S30, measuring the carbon emission generated in the later combustion stage of the fire coal from the coal-fired power plant, wherein the carbon emission includes carbon emission Ws produced in the desulfurization process, carbon emission Wn produced in the denitrification process and carbon emission Wc generated in the decarburization process; and step S40, calculating the carbon emission (Wg= W3+Wgr+Ws+Wn+Wc) generated from raw coal in preset consumption Wcoal consumed in a fire coal life cycle by the coal-fired power plant. The invention adopts the carbon emission calculation range suitable for coal-fired power plants in China and optimal calculation method for measurement of carbon emission from coal-fired power plants, and has the advantage of high accuracy of measurement.

Description

technical field [0001] The invention relates to a method for accurately measuring the carbon emission of a coal-fired power plant. Background technique [0002] According to a large number of literature research, it is found that the current common calculation methods for carbon dioxide emissions of coal-fired power plants in China are mainly divided into five categories: actual measurement method, material balance method, emission factor method, model method and life cycle method. Calculated in terms of wet desulfurization. The actual measurement method requires the power plant to have complete flue gas monitoring equipment, which requires high costs; the material balance method is only suitable for the calculation of carbon emissions in the coal combustion process; the emission factor method requires more data, and the data quality requirements are higher. The workload is heavy, so complete data records are required before calculation. Due to the fact that the data requi...
