WSN series gas / oil fired industrial horizontal steam boiler is a kind of safety and high efficiency heating equipment with fully automatic intelligent control system. It’s a boiler shell type 3 passes wetback oil/gas fired boiler. Usually, the WNS series steam boilers widely used for industry production and processing, such as textile mill, medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, moreover, it could be used for central heating in enterprise, hotel, hospital, civil architecture, etc.
"The fusible plug is a piece of metal or alloy stopping an aperture in some part of the boiler which is directly exposed to the fire, and of such a composition as to melt at a temperature lower than that at which the pressure of the steam would become dangerous.
Fireside Fusible Plug Model 28-403 conforms to ASME standards, with maximum pressure of 250 lbs. Fusible plugs are installed between the fireside of either the plate, flue or tube of the boiler and below the water level; 28-400 models are manufactured to conform to ASME standards and

2019-9-8 · Fireside Fusible Plug Model 28-403 conforms to ASME standards, with maximum pressure of 250 lbs. Fusible plugs are installed between the fireside of either the plate, flue or tube of the boiler and below the water level 28-400 models are manufactured to conform to ASME standards and meet U.S. Coast Guard requirements Fire-activated fusible plugs are filled with pure tin and feature a melting
2016-4-7 · A low melting point alloy within the fusible plug melts with this rise in temperature allowing steam from the boiler to escape into the firebox. This escape of steam if serious alerts the crew to the low water level. Fusible plugs take the form of a bronze or brass threaded plug
The hot steam melts and blows the tin out, allowing steam to escape from the boiler warning the operator. This type of plug can be replaced by closing the valve in the piping. It is not necessary to take the boiler out of service to replace the plug. Fusible plugs should be renewed regularly once a year. Do NOT refill old casings with new tin
2007-8-14 · If the water level drops low enough to expose the fusible plug to steam instead of water, the temperature of the plug will rise, the inner part will melt, and the contents of the boiler will very quickly vent via the firebox, a spectacular and very hazardous event that, should the crew survive, provoke demotion or dismissal.
2019-7-19 · Fusible plugs must comply with only the requirements of A19 and A20 of section I of the ASME Boiler and Pressure Vessel Code (incorporated by reference; see 46 CFR 52.01-1) and be stamped on the casing with the name of the manufacturer, and on the water end of the fusible metal "ASME Std." Fusible plugs are not permitted where the maximum
