Descaling of ship boilers

At present, the main function of the ship's boiler is to provide the life needs of the crew or to heat the cargo oil, and the boiler is easy to produce scale, which not only affects the thermal efficiency of the boiler but also affects the service life of the boiler. In this paper, the common boiler descaling methods are briefly described, and a new descaling technology is proposed to overcome the shortcomings of the existing descaling technology

Marine boiler is installed on the ship to provide power for the ship and achieve the life of the crew of the boiler, according to the use of Marine boiler is divided into Marine boiler main boiler and Marine boiler auxiliary boiler. The main boiler of a Marine boiler is used to produce steam to power the ship. The steam produced by Marine auxiliary boilers is mainly for living needs, and is sometimes used to heat cargo oil. Most Marine boilers are now Marine auxiliary boilers. Marine main boiler is mostly replaced   by diesel engine, gas engine and so on as the ship's main engine.

Dirt is a bad conductor of heat, its existence will reduce the thermal efficiency of the boiler, waste a lot of fuel, resulting in large economic losses and energy waste; Cause metal overheating, strength reduction; Increase the amount of maintenance, waste a lot of money; Shorten boiler service life. General ship boiler descaling using chemical descaling method, but chemical descaling method is not only high cost, pollution to the environment, and chemical reagents are generally corrosive, will corrode the metal wall of the boiler, scale and easy to regenerate.

   Ultrasonic descaling technology is a new technology of GINPERTEC in recent years, which has the advantages of high efficiency, reliable performance, simple operation, low operating cost, and good environment, and has a good application prospect. Ultrasonic scaling device is the use of strong sound field to deal with the fluid in the boiler, the treated liquid medium produced a lot of holes and bubbles, when these holes and bubbles burst or squeeze each other to produce a certain range of strong pressure peak, this strong pressure peak can make the scale material crushed suspended in the liquid medium, and make the physical form and chemical properties of the scale material change. Make it disperse, pulverize, loose off and not easy to adhere to the pipe wall to form scale.

The ultrasonic descaling device developed by GINPERTEC Ultrasonic not only has strong descaling ability, but also has activation and inhibition effect, which can prevent the generation of scale.
