Thermal oil heaters

Revamping/Rehabilitation & Performance increase / new construction
Example; power plants with ORC technology (Organic Rankine Cycle)

  • Findings (existing systems)
  • No electrical energy returns or only small ones
  • Existence of Incrustations by paste like ash particles (high temperatures)
  • Decrease of the remaining free cross section up to 50%
  • Abrasion by decrease of the free cross section, causing an increase of flue gas speeds in the still free cross section up to doubling the values
  • Increasing abrasion of the pipes
  • Thermal oil leaks, pipe breakage, pipe burst
  • Oil fire with unforeseeable material and personal damage
  • Travel time and availability restricted by dirt accumulation
  • Plants designed (only) for maximizing the renewable energy law proceeds

  • Actions
  • Modifications, parameter change
  • Output increase, efficiency increase
  • Reconstruction of the heating surfaces
  • Optimization of the heating surface inflow
  • Combination of irradiation and convection heating surface
  • Decrease of the flue gas speeds
  • Decrease of corrosion, abrasion
  • Extended travel times, lifetime, availability
  • Innovative heating surface cleaning system

  • Result
  • Output increase
  • No slag incrustations
  • No cross section restrictions by slag incrustations
  • No abrasion with reduction of the wall thickness up to breakage and oil fire with the unforeseeable consequences of material and personal damage
  • All pipes with uniform ash coating, a few blank pipe spots
  • No ash incrustations or accumulation respectively on the pipes or between them, not even recognizable in the area of the heating surface cleaning
  • Increased travel time, availability
  • Guaranteed travel time, guaranteed availability
  • Extended lifetime, efficiency increase
