In October 2014, multiple national regulatory agencies introduced a comprehensive mandate requiring strict pollution control and energy conservation upgrades for industrial thermal equipment. Responding rapidly to these rigorous environmental thresholds, our engineering experts initiated an accelerated research program. After six months of intensive technological demonstration, we successfully developed an advanced coal-fired thermal fluid heater seamlessly integrated with a Selective Non-Catalytic Reduction (SNCR) NOx reduction system.

This critical environmental upgrade ensures total compliance with new emission standards without compromising the thermal oil heater’s robust industrial performance. Designed to support demanding manufacturing facilities, the SNCR-equipped hot oil system fully retains our proven combustion architecture. Key engineering advantages preserved in this advanced configuration include:

  • Optimized bi-radial combustion and energy-saving arch structures
  • Advanced secondary air injection for complete fuel utilization
  • Precise flue gas velocity management at the furnace throat
  • Expansive radiation heating surfaces to maximize thermal transfer
  • High-precision temperature control at the furnace exit
