METI / ECCJ / ACE Training Program MTPEC08 (2008.01)

(2) Fired Heaters Fuel Saving vs. Preheated Air (Oil)
(3) Boilers and Steam System
  • EC measures for Boilers & Steam System
  • 1. Boilers
  • - Calculation of boiler efficiency and SEC (Based on
  • Material & Heat Balance using measured values,
  • such as amount of generated steam and fuel
  • consumption) is useful
  • - Air Ratio control
  • - Insulation to reduce heat loss from boilers and
  • related parts
  • - Heat recovery from flue gas and blowdown
  • - Minimum supply steam pressure
(3) Boilers and Steam System
  • EC Measures for Boilers & Steam System (cont.)
  • 2. Distribution (steam piping)
  • - Minimization of steam leakage (Steam traps manage.)
  • - Insulation at piping and fittings
  • 3. End Users
  • - Proper pressure levels
  • - Drain recovery and maximum condensate return
  • - Insulation to prevent heat loss
  • - Temperature control
  • - Proper use of steam traps and air venting
(3) Boilers and Steam System EC Technology of Boilers/Steam System
(3) Boilers and Steam System Standard/Target Air Ratio for Boilers (Japanese Law)
