The fire-tube boiler is a common type of boiler used in industrial settings because it is designed to be efficient in generating steam or hot water by utilizing the heat from flue gases that pass through tubes immersed in water. This design allows for effective heat transfer, making it suitable for various industrial processes that require a reliable source of heat or steam.

Fire-tube boilers typically have a simple construction and can be scaled up for larger applications, which adds to their versatility in different industries. Their ability to operate at lower pressures and their overall lower cost make them appealing for manufacturing, power generation, and even heating applications.

In contrast, while gas-fired boilers are also common, they tend to focus specifically on the combustion of gas for heat rather than the design of the boiler itself. Water-tube boilers are often used for high-pressure applications and are designed differently, leading to greater complexity in operation. Electric boilers are commonly used for smaller tasks or specific applications but are less prevalent in large industrial settings due to cost considerations and energy availability.
