Steam boilers are mainly made of carbon steels, and the internal surface of these metals that are in contact with water must be free of deposits. Deposits have a lower thermal conductivity than metals, which causes the temperature of the metal to rise on the combustion wall side. Therefore, more fuel is needed to produce steam. Therefore, there is a need to control and wash these deposits inside the steam boiler.

Condenser: A unit for controlling temperature in refrigerators, air conditioning systems, and chillers. Its main function is as a heat exchanger in which it converts a substance (refrigerant) from a gas state to a liquid state, from where the latent heat is dissipated by the substance and transferred to the condenser coolant.

Refrigeration is the process of absorbing heat from one fluid and releasing it to another. The fluid can be air, water, or any other gas or liquid. In all refrigeration systems, keeping cool involves absorbing heat from a lower-temperature material and releasing it to a higher-temperature environment.
