Pressure Relief Devices. Pressure relief devices are used to provide a means of venting excess pressure which could rupture a boiler or pressure vessel. A pressure relief device is the last line of defense for safety. If all other safety devices or operating controls fail, the pressure relief device must be capable of venting excess pressure.

Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

There are three main components of a safety valve: disc, nozzle, and spring. The total capacity of the safety valve must be more than the maximum flow capacity (MFC) of the safety valve in case steam valves fail to open. Most steam boilers connect two safety valves in it, but it may require a third safety valve if it does not exceed the MFC.

The safety valve for the boiler compensates for the expansion. arising when heating water. Thus, the work of the indirect water heater and the boiler are closely related. For this type of water heaters, it is required to choose a suitable safety valve. All the characteristics we need are listed in the technical data sheet of the device, so

11/18 · Safety Valves. Safety valves are the major safety component installed on a boiler. Their basic function is to release the pressure built inside the boiler when it exceeds the boiler’s maximum pressure value. This abnormal pressure occurs when other safety functions do not work due to failure. Figure 2.
