Denitrification Facility

Chemical Direct Injection(CDI) SCR SYSTEM

SCR technology introduces NOx generated in combustion facilities with a reducing agent It causes a chemical reaction, converting it into water (H₂0) and nitrogen (N₂), which are harmless to the human body It is a technology that safely discharges into the atmosphere.

In particular the integrated direct injection CDI (Chemical Direct Injection) SCR is As a technology specialized in combined power generation facilities, The reducing agent is directly injected into the HRSG inlet side at the rear end of the gas turbine in the form of an atomizer When starting/stopping the gas turbine, it is discharged excessively due to incomplete combustion Fundamental reduction is possible for NOx.

Additionally, it has the effect of reducing sulfur smoke, so It is a technology that ensures high efficiency and economic feasibility without the need for sulfur reduction facilities.

• Special Features
  • Reduction of NOx (NO+NO₂) generated during initial GT start-up and simultaneous resolution of yellow smoke problem
  • Minimizing installation costs and installation space by miniaturizing/simplifying equipment, solving the problem of lack of space for equipment installation
  • Realizing a safe industrial environment by applying low-concentration ammonia (9%) as a reducing agent
  • Free from PSM, easy to transport/store/handle etc.
  • Ability to respond to the implementation of nitrogen oxide excess surcharge and total emission system due to strengthened air quality regulations
  • Reduced operating costs and initial investment costs compared to existing vaporization method SCR (minimized power consumption)
