Creating the low carbon steam plant

  1. 1. Creating the Low Carbon Steam Plant
  2. 2. The main issues • Meet Carbon Reduction Targets • Reducing energy costs • Life Cycle costs • Providing innovation in design and operation • Save space in plantroom • Provide value for money
  3. 3. Types of Boilerplant • Central Steam • Central MTHW • Central Biofuel Steam • Central Biofuel MTHW • Decentralised LTHW
  4. 4. Two main services • Steam • MTHW
  5. 5. Choice of System: Ability to provide service Steam Systems MTHW Systems  Heating  Heating  DHW  DHW  Chilling  Chilling  Cooking  Cooking  Humidification  Humidification  Laundry services  Laundry services  Sterilisation  Sterilisation  Power generation  Power generation
  6. 6. Steam Plantrooms
  7. 7. Traditional Steam Plantroom Vents from safety valves LTHW Water circuits Flash loss from vent DHW Heat Exchanger Condensate pump Potential for Legionella problems
  8. 8. Issues with traditional steam plantroom design • Flash steam losses • Waterhammer in calorifiers • Duty / standby PRV sets • Cost of separate condensate pump and vent • Problems with Legionella with storage cylinder • Maintenance issues with shell and tube units • Usually supplied as loose parts making costing and installation expensive
  9. 9. Traditional Steam Plantroom
  10. 10. The Modern Low Carbon Plantroom Boiler pressure steam No PRV or condensate pump required DHW LTHW LTHW DHW Variable speed drive pump skid 100% sub-cooled condensate return
  11. 11. Modern Steam Plantroom • Can be connected directly to high pressure steam main • 100% sub-cooled condensate returned to boiler • Greatly reduced steam consumption • No vents required • No condensate pump required • No storage cylinders required • Legionella problems eliminated • Quick installation • Variable speed pumps supplied on skid • No withdrawal distance on exchangers • Much smaller plantroom required • Space can be used for patient areas
  12. 12. Modern Low Carbon Easiheat Plantroom
  13. 13. Alternative Option to Finance
  14. 14. Spirax Rental  No Capital investment required – upgrades/retrofits may be financed via ‘Spirax Rental’  Use energy savings to finance monthly payments  Net savings contribution may be realised from day one  Preserve existing Capital budget  Upgrade/Retrofit can reduce maintenance costs & improve site efficiency & lifecycle costs  Spirax branded Rental Contract
  15. 15. Conclusions  All systems designed to help Hospitals meet stringent CO2 Reductions  Systems will deliver large energy reductions  All systems are packaged for ease of installation  All systems are well planned and project managed  Various finance options available  In most cases plantroom space can be given back to patient care  Hospitals can now have the most energy efficient plant available
