To achieve ultralowemission (ULE) standards, wet electrostatic precipitators (WESP) installed downstream from wet flue gas desulfurization (WFGD) have been widely used in Chinese coalfired power plants (CFPPs). We conducted a comprehensive field test study at four 300 MW level ULE CFPPs, to explor
The formation and emission of sulfur trioxide (SO 3) in coalfired power plants has received increasing attention due to its adverse effects on the operation of plant and environment.With the wide application of selective catalytic reduction (SCR) systems, the problem caused by SO 3 has become severe, especially when high sulfur coal is
This is highly significant to coalfired power plants in achieving longterm stable ultralow emission of pollutants and improving atmospheric environment quality. Here, we describe an integrated pilot plant for hightemperature flue gas dust removal and denitration, which was established on a 1000 MW coalfired unit of a power plant.
Flue gas desulfurization gypsum (FGDG) is an industrial byproduct generated during the flue gas desulfurization process in coalfired power plants. Due to its abundance, chemical and physical properties, FGDG has been used in several beneficial applications. However, during the past decade, the rate of beneficially used FGDG has
In CO 2 emissions from coalfired power plants rose to a record 9.7 Gt, representing an increase of nearly 6.6% from the previous year and more than 100 Mt above their previous peak in . Without the supply
gypsum is the waste produced in the process of flue gas desulfurization of coalfired power plants. Each ton of SO2 can produce 2.7 ton byproduct FGD gypsum. With the rapid development of coalfired power plants, the amount of FGD gypsum will be more and more, and it will become the second largest solid waste after fly ash.
