Boiler Steam Boiler: A steam boiler is a sealed container, typically constructed from steel, where water is heated using a heat source generated by fuel combustion, accordingly producing steam. This steam can be delivered at low pressure for various industrial processes, such as in cotton mills and sugar production, as well as for generating hot water that can be utilized in heating systems at lower pressures.   Steam:  Steam is the vapor produced when water transitions from a liquid to a gaseous state. At the molecular level, this occurs when H2O molecules break free from the hydrogen bonds that hold them together. In liquid water, these molecules are in a constant state of bonding and separation. However, as the water is heated, the bonds between the molecules begin to break more quickly than they can reform. Eventually, with sufficient heat, some molecules escape, resulting in the formation of the transparent gas known as steam, or more specifically, dry steam. Steam ha...

Cooling Tower Cooling tower is a typical cooling methodology where air and water come into direct contact to reduce the temperature of the water. In this case, the temperature of the water flowing through the tower decreases by observing the air temperature while this process evaporate small amount of water. Heated water from industrial processes or air-cooled condensers is pumped through pipes into the cooling water pipes. The water is sprayed through nozzles into objects called "collectors", which allow the water to flow through the cooling air and disperse as much water as possible into the water. As the water passes through the cooling tower, it is exposed to the air, which is drawn through the tower by fans driven by an electric motor. When water and air meet, a small amount of wat...
