It consists of a metal plug with a core made of low melting point material, typically a lead-tin alloy or a similar composition. The working principle of a fusible plug can be summarized as follows: Construction: A fusible plug is typically installed in a chamber or a plate within the pressure vessel. It is designed to withstand normal operating conditions, but its core material has a lower melting point than the surrounding metal components. Melting Point: The core material of the fusible plug is selected to have a melting point below the desired maximum operating temperature of the vessel. The melting point can vary depending on the specific application and safety requirements. Overheating or Excessive Pressure: If the temperature of the pressure vessel rises to a level above the melting point of the core material or if the pressure within the vessel exceeds a certain threshold, the fusible plug comes into action. Core Melting: When the core material reaches its melting point, it begins to melt, losing its structural integrity. As the core material melts, a hole or passage is created through the plug. Pressure Release: Once the core material has melted, the pressure within the vessel is able to escape through the hole in the fusible plug. This rapid release of pressure helps to prevent catastrophic failure of the vessel. Alarm or Shutdown: The opening of the fusible plug typically triggers an alarm or shutdown mechanism, notifying operators or initiating safety protocols to address the issue that caused the excessive temperature or pressure. Fusible plugs are designed as a last line of defense to prevent catastrophic failures in pressure vessels. They provide a means for pressure relief in case other safety devices fail or are overwhelmed. It's important to note that after a fusible plug has been activated, it needs to be replaced to restore the safety function of the pressure vessel. The specific design and installation of fusible plugs may vary depending on the application and regulatory requirements. It is essential to follow the manufacturer's guidelines and applicable safety standards when implementing and maintaining fusible plugs to ensure proper operation and system safety. #boilers #steamboiler #firetubeboiler #boilerservicing #highpressureboilers #watertubboiler #boilermountings #boileraccessories #boilerbasics #industrialboilers #industrialsafety #compitativeexams #mechanicalengineering
