CRUST PREVENTION ON HEAT TRANSFER SURFACES USING COMBINED MAGNETIC AND ULTRASONIC METHODS
ABSTRACT
It is widely recognized that the heat transfer is decreasing at the air compression plants due to deposits yielded by the cooling water.
Besides the chemical and mechanical conventional methods, the literature quotes trials of preventing these phenomena using magnetic and/or ultrasonic methods.
The paper presents a case study using a water-air heat exchanging system in an air compression plant to which a magnetic field and ultrasounds were applied. The heat transfer indexes are computing starting from the equipment's geometry and working conditions. Correspondingly, deposit microstructures in various working regimes and conditions and the treatment method efficiencies are shown as well.
