A boiler (steam boiler), also known as a steam generator, is a closed-vessel steam-producing unit made of steel or other materials with similar properties. Inside the vessel, both water and steam are contained. Boilers are designed and constructed to be strong and durable, with operational processes that vary according to proper engineering standards.
Boilers, or steam generators, play a vital role in industrial production. They serve as a key component in manufacturing processes, offering numerous benefits such as increasing production rates, reducing costs, saving time, and conserving energy, while also providing greater convenience. Boilers are capable of operating with excellent efficiency and are closely monitored and controlled by specialized experts to ensure optimal performance.
The steam energy produced by boilers is transferred to machinery to enable operation, as boilers offer lower energy costs compared to using electricity directly with machines. Moreover, the term boiler does not refer only to steam generators, but also includes hot water boilers and thermal oil heaters.

Utilized for generating other forms of energy, such as powering machinery in industrial factories and supporting transportation systems.
Acts as a high-temperature heat source for sterilizing various types of microorganisms invisible to the naked eye, such as certain bacterial contaminants. This process is commonly used in hospitals, hotels, and for items like bed linens, pillows, utensils, and food containers, where steam treatment is required for sterilization before reuse.
Used as a heat source for cooking or drying, especially in industrial food production processes that require large-scale output. Boilers provide the necessary heat for convenience, speed, and consistent batch production, resulting in significant savings in both time and cost.
Boilers are also used in cooling applications, particularly in cold storage services, to preserve the temperature of fresh food products and prevent spoilage.
