SERCs focus pellets solar

• Based on results from earlier projects
• Pesto IEA Task 26 studies with Chalmers
• Interaction between pellets burner/boiler, store
  and solar
• Compact solution
• Integrated burner (pellets integral?) alt. closed
  coupled boiler
• Investigation of vacuum insulation
• Control
• Burner for minimized emissions (mainly start
  stop)
• System control solar, burner and heating system
  is controlled by one central control unit
• System simulations optimisation
• Including results from the other groups
• Advantances storage, stratification pipe,
  advanced floor heating..
• (Development/optimisation of pellets
  burner/boiler, flue gas condensation, building
  integrated pellets storage,)

Review first half 2003

• TRNSYS Simulation course
• Survey The Application of renewable Energy for
  Prefab Houses in Germany
• Simulation studies with TRNSYS Investigation of
  a combisystem combined with a store integrated
  pellet burner burner
• Study of different Pellet burner/boiler designs
• Study of combisystems results from Task 26
• Contact to distributor of vacuum insulation

BioSol/PellX

• Leakage heat losses during off periods of the
  burner if no flap is installed
• Optimisation of the control parameter
• Simulated system
• Combisystem 12 Task 26 PellX burner
  (Scand-Pellet AB) and Bio-Sol storage (Stocksbro
  AB)
• storage and burner parameter are identified
  parameter from measurements of a test system at
  SERC, burner model type 208 (S. Nordlander)

• In such a system more than 7 of the annual
  energy demand is used to cover leakage heat
  losses through the air to liquid heat exchanger
  of the store
• Installation of a flap is required from the
  manufacturers
