Which of the following statements about vertical boilers is false?

The assertion that vertical boilers can only burn one type of fuel is incorrect. In practice, vertical boilers are versatile and can be designed to accommodate multiple types of fuels. This flexibility allows them to be adapted to different operational needs and fuel availability. For example, many vertical boilers are capable of burning natural gas, oil, or even biomass, providing operators with choices that can optimize efficiency and costs based on the specific fuel used.

On the other hand, vertical boilers are indeed often used in specialized applications due to their compact design, making them ideal for settings where space is limited or specific steam generation needs arise. Their smaller footprint allows them to fit into tighter spaces, which is a significant advantage in many industrial environments. Furthermore, vertical boilers are designed to handle higher steam pressures effectively, making them suitable for applications that require efficient steam generation at such pressures. This multi-functional capability reinforces why the idea that they can only burn one type of fuel is inaccurate.
