  • Fuel consumption was based on the net heating value.
    (Light Oil: 10,300 kcal/kg, LNG: 11,000 / 10,000 kcal/Nm3, LPG + AIR: 15,400 / 14,500 kcal/Nm3, Propane: 24,350 / 22,400 kcal/Nm3, Butane: 31,840 / 29,500 kcal/Nm3)
  • Calorie generation was based on the steam pressure of 10kg/cm2, steam enthalpy of 663.7 kcal/kg, and feed water temperature of 20℃.
  • Boiler efficiency is under rated load based on the net heating value. (optional feature for high-efficiency boiler)
  • Boiler efficiency and calories can be reduced depending on site conditions as well as measurement error.
  • Identical low and inter-stage pressure, gas valve specification
  • Governor should be installed for inter-stage pressure.
  • The above specification table can be unexpectedly changed in order to improve performance.
