Steam boilers are vital in various industries, converting water into steam for purposes such as power generation, heating, and industrial processes. These closed vessels heat water under high pressure, producing steam that can be used in applications like driving turbines in power plants, heating systems in buildings, and various industrial processes in sectors like chemical, food processing, and refineries.Boilers come in different types, including fire-tube, water-tube, and electric boilers, each suited to specific applications based on the required pressure, temperature, and fuel type. Key components include the furnace, burners, boiler bank tubes, steam drum, superheater, economizer, and control systems, all working together to ensure efficient steam production.
