Utilisation économique de la chaleur perdue

  • Encombrement et poids réduits
  • Nettoyage possible pendant le fonctionnement du moteur, de la turbine ou du processus
  • La sortie peut être ajustée en fonction des besoins
  • Permet de prolonger l'intervalle entre les nettoyages majeurs, par exemple via le mode de fonctionnement à sec
  • Faible inertie
In any operation, there is almost always room to continue reducing power consumption and related costs. The secret is in reclaiming the energy lost as exhaust gas heat. As the pioneer in waste heat recovery, Alfa Laval has the technology and expertise to help you further increase your energy efficiency.

Design

The Aalborg Micro is build in a durable design featuring a heating surface consisting of a number of coaxial tubes arranged in a vertical or horizontal cylindrical shell plate. This, ensures a long-term, trouble-free performance and offers capacities ranging from approximately 250-5000 kW.

The heating surface of the Aalborg Micro has been developed for easy maintenance. Cleaning can be performed either with a pyrolysis process when operating in dry-run mode or using optional soot blower rings with compressed air, steam or water.
