An industrial boiler is a large vessel that heats water or other fluids to generate steam or hot water for various industrial processes. These boilers are essential in manufacturing, power generation, and heating applications, providing the necessary heat for operations like food processing, chemical production, and electricity generation. Industrial boilers come in different types, including fire-tube and water-tube designs, each suited for specific applications. They are typically fueled by natural gas, oil, or biomass, and must comply with safety and environmental regulations to minimize emissions and ensure efficient operation. Proper maintenance is crucial for their longevity and performance.
