Heat Management HISS

The patented HISS enhancement system optimizes steam sootblowing and delivers significant savings, improved efficiency, and environmental benefits for recovery and power boilers – without mechanical modifications to the sootblowing equipment or any reduction in cleaning performance.

TECHNICAL SOLUTION

  • Add-on device – no changes to the existing sootblowing system
  • Instrument air requirement – 6 bar
  • Alternative implementation scopes
    • HISS Advanced – includes software modification; installation requires a shutdown
    • HISS Essential – no software changes; installation during production

WARRANTY

  • System warranty: 2 years
  • Guaranteed steam savings: 30% compared to current usage

ACHIEVABLE BENEFITS

  • At least 30% steam savings compared to current levels – with cleaning performance maintained or improved
  • Sootblowing cycle time halved
  • Increased boiler capacity – more production, fewer shutdowns
  • Higher boiler load possible without increasing steam consumption
  • More electricity – saved steam can be utilized for energy production
  • Reduced need for fresh boiler water – lower water consumption and costs
  • Lower CO₂ emissions: saving 1 ton of steam equals approximately 0.2 tons less CO₂ emissions

INVESTMENT

  • Short payback period

OPERATION AND MAINTENANCE

  • Minimal maintenance requirements – reliable solution with no need for scheduled servicing
  • Reduced wear on heat transfer surfaces – longer operational life and less maintenance
