How to Use This Calculator

Key Parameters Explained

Steam Production Parameters


  • Steam Rate: Hourly steam output (typical range: 1-100 ton/h)
  • Steam Pressure: Operating pressure (common range: 5-40 barg)
  • Feed Water Temp: Inlet water temperature (typically 80-120°C)

Operational Parameters


  • Annual Days/Hours: Plant utilization rate (adjust using sliders)
  • Burner Efficiency: Combustion system efficiency (modern: 85-95%)
  • H₂ Blend: Hydrogen percentage in fuel mix (0-100%)

Example Calculation

Typical Industrial Boiler

Steam Rate: 10 ton/h
Pressure: 15 barg
H₂ Blend: 30%
Result: 4.2 MW electrolyser | 35% CO₂ reduction

Optimization Strategies


  • Every 10% H₂ blend reduces CO₂ emissions by ~7-9%
  • 5% improvement in burner efficiency = 15% fuel savings
  • Higher steam pressures increase energy density but require stronger piping
  • Pre-heating feed water reduces fuel consumption

Safety Considerations

Never exceed boiler manufacturer's maximum pressure rating

Maintain exhaust gas temperatures below 200°C

Hydrogen blends above 20% require burner modifications

Technical Notes


  • Calculations based on ASME steam table approximations
  • Includes real-world burner efficiency derating
  • Emissions factors from UK Government 2024 guidelines
