Waste heat recovery

Often waste heat recovery cannot be realized as a consequence of fouling or heavy dust loads in flue gases. Waste heat then remains what it is: waste heat, to be discharged through the chimney.

OPTIMUM developed a system for the line in cleaning of tubes in heat exchangers, combined with a specially designed heat exchanger or boiler. With this system- APCS Automatic Pipe Cleaning System- heat exchangers and boilers can be cleaned during operation.

Down time is no longer required for the removal of heavy loads of dust and other kinds of fouling. With the APCS- worldwide patented by OPTIMUM- waste heat recovery has now become reality and opens wide  and new perspectives for different kinds of industrial processes, where  up till now heat recovery was something to dream of.

OPTIMUM has realized waste heat recovery references in a wide range of industries

  • Demolition wood combustion
  • Rendering industry
  • Industrial waste combustion
  • Activation and reactivation furnaces of activated carbon
  • Municipal waste combustion
  • Biomass combustion (several agricultural residues)
  • PCB recycling
  • Sulphuric acid industry (alkylation) thorugh MECS DUPONT
  • Glass industry

Waste heat recovery by preventing fouling problems

OPTIMUM has developed different waste heat recovery concepts. In the glass industry for instance, we are able to recover the heat to reduce the energy consumption of the primary process by using the steam to preheat furnace feed streams like cullet and pelletized batch. In other industries we mainly focus on using the thermal energy, provided the energy can be recovered. Expanded with an OPTIMUM waste heat boiler system, industrial processes can now contribute tremendously in Co2 emission reduction and their carbon footprint! It is obvious that increasing costs of fossil fuel provides  that the increasing costs of fossil fuel provides  the best incentive for waste heat recovery projects as a sustainable and cost reducing concept.

Waste heat recovery concepts

  • Demolition wood combustion
  • Rendering industry
  • Industrial waste combustion
  • Activation and reactivation furnaces of activated carbon
  • Off gas of combustion is several gasification processes
  • Off gas of printed circuit board combustion
  • Municipal waste combustion
  • Biomass combustion (several agricultural residues)
  • Glass industry

Automatic Pipe Cleaning System APCS

  • A combination of an OPTIMUM designed waste heat boiler with APCS guarantees a maximum availability and trouble free operation
  • APCS cleans the surface area while the system is in operation. There is no need to shut down
  • Stable process conditions for the up- and downstream processes.
