Thermal Power Plant
Boiler flue gas desulfurization and denitrification, fly ash collection, silo discharge and ash conveying.
Working condition
Recommended configuration
Each row shows the process stage, the machine we normally select and the point that decides whether it performs on site.
| Process stage | Recommended equipment | Selection point |
|---|---|---|
| Fly ash collection | Electrostatic precipitator, dry or wet typeGP-CDPK / GP-WESP Series | Wet ESP as a polishing stage after wet FGD for fine particles and droplets. |
| SO₂ removal | Wet limestone-gypsum desulfurization towerGP-FGD Series | Spray layer number set by inlet SO₂, glass flake lining for chloride resistance. |
| NOx removal | SCR reactor in high dust arrangementGP-SCR Series | Use the existing temperature window to avoid gas reheating, catalyst layers per inlet NOx. |
| Ash discharge and lifting | Rotary airlock, drag chain conveyor, bucket elevatorGP-MS / GP-FU Series | Enclosed casing with hardened liners, interlocked level and speed monitoring. |
| Auxiliary power saving | MV VFD retrofit on ID fan and pumpsGP-VFD Series | Bypass cabinet keeps production running if a drive trips. |
Energy
Ultra-low emission requirements are defined by the local environmental authority and the plant permit. Outlet values are verified by CEMS under actual load and fuel quality.
