Embodiment
Fig. 1 is the structural drawing of the application's background technology.
Fig. 2 is the application's a schematic diagram, and the application is devoted to improve measuring equipment accuracy and reliability, the exit gas quality is carried out the additional areas monitoring, measured in real time.
As shown in Figure 1, at the reversal chamber 4 internal fixation flue gas guiding devices of economizer 7 top flue inflow points, the flue gas guiding device is made up of 2 identical fair water fins 3 of structure, and fair water fin 3 is the angle bar shape, two straight flange arc transition.Two equidistant up and down parallel crosswise fixed that stagger of fair water fin 3 are divided into three parts with reversal chamber 4 in reversal chamber 4.
As shown in Figure 2, this fly-ash separator side accurate measuring systems comprises that this fly-ash separator side accurate measuring systems comprises shell, calibrating installation, one group of carbon dioxide flow analyser, one group of insertion type probe, one or more analysis room, and this analysis room has regional analysis assembly and automated cleaning assembly.
As shown in Figure 3, there are the unevenness of flow velocity, temperature and composition in the air of any xsect of flue of flowing through and flue gas, especially in the flow disturbance zone.Owing to the subtle change of fuel and air-supply, this uneven components or layering be time to time change also simultaneously.Consider the influence of these factors, adopt and choose more check point or adopt more complicated computing method to reduce result's uncertainty.For the influence that compensates laminar flow and in order to obtain representative mean value, must on perpendicular to the plane of flow direction, carry out multimetering.Carrying out gridding method according to EPA methodology 1 divides and measures.
As shown in Figure 4, be a cross-section of pipeline.Measured pipeline is divided into the region unit (among the figure being 4) that some areas equate, measures the central speed of each region unit respectively, the central speed with each region unit carries out arithmetic mean calculating again, can obtain the average velocity of pipeline.Probe position and the quantity of sampling on the cross section will be determined according to factors such as the sectional area of pipeline and cross sectional shapes.In the process that sampling is analyzed, to consider that also sampling bias is to the influence of uncertainty as a result.
