What is a potential consequence of scale formation on a float-operated boiler supply valve?

• A. Reduced efficiency
• B. Flooding of the boiler
• C. Increased energy consumption
• D. Noise from the valve

Answer: (B)

Scale formation on a float-operated boiler supply valve can hinder the proper operation of the valve, which is crucial for maintaining the desired water level in the boiler. When scale builds up, it can obstruct the flow of water, leading to an imbalance in the water level. This imbalance can cause the boiler to flood, as the valve may fail to respond appropriately to the float mechanism due to the restricted flow. Flooding can result in serious operational issues, including reduced heat transfer efficiency, potential damage to the boiler, and even hazardous conditions. While reduced efficiency, increased energy consumption, and noise from the valve can indeed be consequences of various problems within a boiler system, the most direct and critical consequence of scale formation specifically affecting the functionality of a float-operated valve is the risk of flooding. This highlights the importance of regular maintenance and treatment of boiler water to prevent scale and ensure safe and efficient operation.
