摘要/Abstract

摘要：

采用稀释采样方法对一台220 MW煤粉炉(锅炉A)及一台300 MW的CFB锅炉(锅炉B)电袋复合式除尘器前后PM_2.5进行现场采样。通过ELPI测定PM_2.5的粒径分布;采用SEM分析PM_2.5的显微结构;采用EDX及ICP-OES分别对分级PM_2.5中次量及痕量元素含量进行了检测。结果表明,锅炉A和B除尘前后对应的PM_2.5粒数及质量浓度分布均不同;锅炉A和B产生的PM_2.5分别以较为光滑球形和不规则形状为主,锅炉A除尘后PM_2.5呈表面粗糙球形,锅炉B除尘后PM_2.5单颗粒形貌特征不变;锅炉A和锅炉B产生的PM_2.5除尘前后在各粒径段中Si、Al、Fe、Ca和Mg含量基本一致,As、Cd和Se含量随着粒径的减小而增大;除尘后锅炉A产生PM_2.5中As和Se含量增加,且在亚微米PM_2.5中As和Se含量的增加更明显,锅炉B除尘后PM_2.5中As和Se含量基本不变。

Abstract:

A dilution sampling method was used to collect PM_2.5 before and after COHPACs (compact hybrid particulate collector) generated by a pulverized coal boiler (boiler A) and a circulating fluidized bed boiler (boiler B) with installed capacities of 220 MW and 300 MW, respectively. Particle size distributions (PSDs) of PM_2.5 were analyzed by ELPI; individual microstructures of PM_2.5 were analyzed by SEM (scanning electron microscopy); concentrations of minor elements in PM_2.5 were analyzed by EDX (energy-dispersive X-ray analysis) and concentrations of trace elements in PM_2.5 were analyzed by ICP-OES (inductively coupled plasma optical emission spectroscopy). The distribution characteristics of number and mass concentration of PM_2.5at the corresponding sampling positions of two boilers were different. Most of the PM_2.5 before and after COHPAC-A (boiler A's) were spherical; most of the PM_2.5 before and after COHPAC-B (boiler B's) were irregular in shape; the PM_2.5 after COHPAC-A were with relatively uneven surface, PM_2.5 microstructures before and after COHPAC-B were similar; mass fraction size distributions of Si, Al, Fe, Ca and Mg in PM_2.5 before and after the two COHPACs were similar; mass fraction size distributions of As, Cd and Se in PM_2.5 before and after the two COHPACs increased with decreasing size; mass fraction size distributions of As and Se in submicron PM_2.5 after COHPAC-A were higher than those before COHPAC-A, but mass fraction size distributions of As and Se in PM_2.5 before and after COHPAC-B were correspondingly nearly the same.

Key words: PM_2.5, pulverized coal boiler, CFB, particle size distribution, COHPAC, microstructure, minor and trace elements
