Coal-fired flue gas desulfurization and denitrification project

TZCO has a professional R&D team for desulfurization and denitrification of coal-fired flue gas, covering the whole process of R&D, design, manufacturing and construction, and has the general contracting capacity for desulfurization and out-of-stock projects.

  • Processing capacity: 100,000 ~ 500,000 Nm³/h
  • NOx in the treated flue gas≤100mg/m³.
  • SO2 in the treated flue gas ≤20mg/m³.

  • Process Instruction

    The desulfurization and denitrification process of coke oven flue gas is mainly to reduce the content of nitrogen oxides, SO2 and particulate matter in the flue gas, so that the flue gas emission can meet the relevant national and local standards. The desulfurization and denitrification process of coke oven flue gas is mainly composed of flue gas system, desulfurization unit, denitrification unit, ...
