NTPC: HARIT KOYALA PARIYOJANA

Operational Challenge.

  • Volatile Gas (VG) Pipeline Choking.
  • 40mm Concentric Tar & Sludge Buildup.
  • Flammable Process Environment.

GRASS ENGG proposes a Hydraulically Powered VG Pipeline Cleaning System. Utilizing existing fire hydrant infrastructure, the platform features a zero-ignition-risk mechanical turbine to cut through hardened tar and char deposits without introducing electrical components into the flammable gas stream.

The system is engineered to navigate 400-500mm pipelines, traversing bends and extended horizontal stretches to reduce current manual maintenance cycles by at least 50%.

Key Engineering Imperatives:

  • Intrinsically safe operation (No onboard electronics).
  • Remote deployment outside confined spaces.
  • Hydraulic debris transport for controlled extraction.
