Boilover in liquid hydrocarbon tank fires Semantic

Boilover is a violent ejection of certain liquid hydrocarbons due to prolonged burning during a storage tank fire.It happens due to vaporization of the water sub-layer that commonly resides at the base of a storage tank,resulting in the ejection of hot fuel from the tank,enormous fire enlargement,formation of a fireball and an extensive ground fire.Boilover is a very dangerous accidental results for this questionFeedbackStorage Tank FiresVent fires.vent fires are typi tanzania floating roof oil tank firey associated with fixed roof tanks such as cone and internal floating roof tanks.the main cause is a lightning strike that ignites fugitive vapors which may be present at the vent.this is a less severe type of fire and can usually be extinguished with a dry chemical fire ex-tinguisher or by reducing the pressure in the tank. results for this questionHow does oil get into a fixed roof tank?How does oil get into a fixed roof tank?Vapor no longer came out of the vents,air got in,and a mild explosion occurred inside the fixed-roof tank.This forced the floating roof down like a piston,and some of the crude oil came up through the seal past the side of the floating roof and out of the vents on the fixed-roof tank.Floating Roof Tanks - an overview ScienceDirect Topics

Lightning Protection of Floating Roof Tanks

Because of the content of a floating roof tank which is crude oil,the tank contains flammable vapour,also oxygen is readily available in the environment and at a potential of about 3KV/mm the flammable airvapour (acting as a di-electric) within the gap will break down and conduct electricity in the form of a spark(arc).This completes the fire triangle resulting in a lightning induced floating roof tankOil floating roof tanks Signaline Linear Heat Detection The danger posed by fire in an oil storage facility is obvious.The roofs of storage tanks rise and fall as the tank is emptied and filled.Signaline HEAT Linear Heat Detection around the floating roof rim together with a coiled extendible cable to link the Signaline HEAT Linear Heat Detection to the tank superstructure is commonly used to sense the early stages of a developing fire.Oil tank protection - AccuroThe fire protection concept is determined by the tank design and the liquids stored in it.If,for example,it is an oil tank with a floating roof,the fire detection or extinguishing system will be concentrated on those areas in which the flammable liquids come into contact with the air (oxygen).
