Boiler scaling is the accumulation of mineral deposits on the internal surfaces of a boiler.
Boiler scaling occurs when minerals in the water, such as calcium and magnesium, precipitate out and form a hard, insulating layer on the boiler's heat transfer surfaces.
Scaling reduces heat transfer efficiency, increases energy consumption, and can lead to overheating and equipment failure.

Each type of chiller, compressor, and plastic has its own unique properties and applications.
Gear box is a mechanical device that transmits power from an engine to the wheels. There are various types of gearboxes.
Gearboxes are used in automobiles, industrial machinery, and other applications.
The most common types of gearboxes are manual, automatic, and continuously variable transmissions (CVT).
Manual gearboxes require the driver to manually shift gears using a clutch and gear stick.
Automatic gearboxes shift ge...

There are two types of chillers: air-cooled and water-cooled. Common refrigerants include R-22, R-134a, and R-410A.
Air-cooled chillers use air to remove heat from the refrigerant, while water-cooled chillers use water.
R-22 is a commonly used refrigerant, but it is being phased out due to its harmful effects on the environment.
R-134a is a more environmentally friendly refrigerant, but it is less efficient than R-22.
R-41...

Heat transfer types include conduction, convection, and radiation. Kettle type reboiler is a type of heat exchanger used in distillation processes. ISO systems are international standards for quality management.
Conduction transfers heat through a material without any movement of the material itself
Convection transfers heat through the movement of fluids or gases
Radiation transfers heat through electromagnetic waves
Kett...
