In case of a boiler, scale is made on the surface of tube by the chemical reactions of Ca and Mg ions contained in the water and heat transfer rate is reduced because of the increment of heat resistance. Thus, it brings about the reduced energy transfer efficiency and also environmental pollution due to the use of chemicals for scale removing. Scale prevention experiments in the real small boiler tell us exposed sample results in 3659% less scale formation than an unexposed one.
Boilers, Heat Exchangers, Chillers and nearly any metal heat exchange surface are now able to operate more efficiently and no longer need to have scale, sludge, or fouling removed.
In a recent test case at a GS-Caltex Facility. The Morko USP was installed on #1 CDU, Crude Pre-Heat Exchanger. For the test they ran 12 months to compare inlet and outlet temperatures and compared them to the adjacent line without the USP installed. Results: Heater coil inlet temperature (CIT) difference: from -4°C to +4°C. [...]
