About Customer

Heat Treatment & Steam Generation Applications

For years, Hindustan Engineering & Industries Ltd., a prominent railway casting company in Hooghly, West Bengal, battled pollution, inconsistencies in fuel and product rejections. Their heat treatment furnaces, running on LSHS fuel, were unpredictable. Maintenance crews worked overtime fixing constant breakdowns, while management worried about failing RDSO's strict emission tests.

The turning point came when they switched to SUPERGAS LPG. Their furnaces delivered consistent, precise heating every single batch. Maintenance schedules relaxed, emissions dropped dramatically, and environment compliance became effortless.

“Low Sulphur Heavy Stock (LSHS) is a high-viscosity liquid residual which needs constant pre-heating and specialised handling. It’s high pour-point causes wax solidification at ambient temperatures, makes it difficult to maintain the stable, precise temperature control necessary for consistent heat treatment.”

LPG Solution Offered

Challenges with LSHS Heating System

Before switching to LPG HEIL faced challenges with their heating system that is both costly and non-compliant.

  • Required 60 litres of LSHS to heat just 1 ton of railway castings, with only 65-70% efficiency - meaning 30% of fuel was simply wasted.
  • Burners took 20-25 minutes just to start, causing significant downtime and productivity loss.
  • Inconsistent heating resulted in uneven temperatures, leading to frequent product rejections and rework costs.
  • LSHS spills posed daily risks, requiring specialized handling teams and constant vigilance.
  • Struggled to meet Railway's RDSO emission standards due to high carbon footprint and greenhouse gas emissions.
