    Step 4: Determine Boiler Energy The boiler energy is calculated as the difference between the total outlet (steam, blowdown) energy flows and inlet (feedwater) energy flows. Step 5: Determine Fuel Energy The total required fuel energy is determined by dividing the boiler energy by the Combustion Efficiency.Learn More

  • INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

    Typical Energy Balance of a Boiler/Heater (before improvements) Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler.Learn More
