fusible plug

Subsequently, due to a leaking fusible plug, it has been out of service for quite some time.

Lead fusible plugs may be present in the crown of the firebox.

Here in 1854, he invented and patented a fusible plug for steam boilers.

Trevithick also added a fusible plug of lead, positioned in the boiler just below the minimum safe water level.

The tube plates, the fusible plug and the heads of the firebox stays should be checked for leaks.

From then on it was accepted that the correct action in the event of the operation of the fusible plug was to add water.

The cored fusible plug was developed in the 1860s to give a wide opening as soon as the alloy softens.

A fusible plug operates as a safety valve when dangerous temperatures, rather than dangerous pressures, are reached in a closed vessel.

Fusible plugs are common in aircraft wheels, typically in larger or high-performance aircraft.

A patented type of fireproof safe uses a fusible plug to douse its contents with water if the external temperature gets too high.

The development of the fusible plug to release pressure in conditions of excessively high temperature and low water levels was designed to protect against this occurrence.

A fusible plug is a threaded metal cylinder usually of bronze, brass or gunmetal, with a tapered hole drilled completely through its length.

The state Inspector of Boilers checked the boiler's fusible plug and determined that the explosion was not caused by a lack of water.

Fusible plugs are sometimes fitted to the receivers of air compressors as a precaution against the ignition of any lubricating oil vapour that might be present.

In steam engines the fusible plug is screwed into the crown sheet (the top plate) of the firebox, typically extending about an inch (25mm) into the water space above.

The cause of the explosion was later said to be the failure of a safety valve (called a "fusible plug") to blow when the water level in the boiler fell too low.

Such alloys are used for making the fusible plugs inserted in the furnace crowns of steam boilers, as a safeguard in the event of the water level being allowed to fall too low.

Automobile air conditioning systems were commonly fitted with fusible plugs, operating at 100-110 C, but from concerns about the environmental effects of any released refrigerant gas this function has been taken over by an electrical switch.

In commercial laser systems, hazard mitigations such as the presence of fusible plugs, thermal interrupters, and pressure relief valves reduce the hazard of, for example, a steam explosion arising from an obstructed water cooling jacket.

Fusible plug - placed at the lowest level of water and above the combustion chamber, its function is to extinguish the fire as soon as the water level in the shell of the boiler falls below a certain marked level.

Fusible plugs over the firebox melt at a temperature lower than that of the firebox plates, thereby warning the operators by the noisy escape of steam if the water level is too low to cool the firebox crown safely.

During an RTO test most of the kinetic energy of the airplane is converted to heat by the brakes, which may cause the fusible plugs of the tires to melt, causing them deflate; and small fires may start.

The very large thermal loads imposed by abnormal landing and braking conditions (an RTO notably) can cause already high pressure in the tyres to rise to the point that the tyre might burst, so fusible plugs are used as a relief mechanism.

The initial use of the fusible plug was as a safety precaution against low water levels in steam engine boilers, but later applications extended its use to other closed vessels, such as air conditioning systems and tanks for transporting corrosive or liquefied petroleum gasses.
