  • Pyrolysis of low-density polyethylene using synthetic catalysts produced from fly ash

    Catalytic pyrolysis of low-density polyethylene (LDPE) was investigated using various fly ash-derived silica–alumina catalysts (FSAs). FSAs were prepared by a simple activation method that basically includes NaOH treatment of fly ash by a fusion method, followed by an aging process. A series of LDPE pyrolysis experiments was conducted and the catalytic performance of FSAs was assessed in terms of ...

  • Inorganic contaminants attenuation in acid mine drainage by fly ash and its derivatives: column experiments

    Treatment of AMD with fly ash (FA) is a promising technology but solid residues (SR) generated in the process pose a disposal challenge. This study evaluates the suitability of the SR and SR, FA/ordinary Portland cement (OPC) blends for backfill in mine voids and in–situ treatment of AMD flows. The mitigation of AMD in a mine void was simulated by addition of simulated acid mine drainage ...

  • Mercury speciation and distribution in a 660-megawatt utility boiler in Taiwan firing bituminous coals

    Mercury speciation and distribution in a 660-MW tangential-fired utility boiler in Taiwan burning Australian and Chinese bituminous coal blends was investigated. Flue gases were simultaneously sampled at the selective catalytic reduction (SCR) inlet, the SCR outlet, the electrostatic precipitator (ESP) outlet, and the stack. Samplings of coal, lime, bottom ash/slag, fly ash, and gypsum slurry ...

  • Characterisation for some emission sources in CMB calculation for Mae Moh area, Thailand

    Particulate samples of agricultural waste burning, straw burning, forest leaf burning, heavy duty truck emission, paved road dust, soil, agricultural soil, coal, electrostatic precipitator ash, and emission from stack power plant were collected from the Mae Moh area. Chemical compositions of sampling filters were analysed to determine the particulate matter source profiles. The analysis included ...

  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Static and dynamic back-corona characteristics

    Voltage-current characteristics are a basic tool to analyse the operational conditions of an electrostatic precipitator, and to detect the onset of Back-corona, that strongly affects the collection performances. In this investigation, a laboratory set-up has been arranged, with a classical ESP wireplate configuration; both static and dynamic voltage-current characteristics have been measured and ...
