Oil fumes, natural gas, propane, coal, or any other fuel can build up inside the combustion chamber. This is especially of concern when the vessel is hot; the fuels will rapidly volatilize due to the temperature. Once the lower explosive limit (LEL) is reached, any source of ignition will cause an explosion of the vapors.
The combustion chamber (A) is filled intermittently with an air–fuel mixture supplied by the gas chamber (C) and the air chamber (B). The air–fuel mixture is ignited by a spark after which the explosion of the mixture causes an increase in pressure throwing open the nozzle valve (F), allowing the compressed gases to flow through the nozzle ...
The combustion chamber of the Velox could produce flue gasses by burning fuel gasses or heavy fuel oil. Blast furnace gas was typically used as fuel by Velox sets installed in steel mills. Efficiency of Velox steam generators was generally around 88—90% when burning blast furnace gas and 91—93% per cent with fuel oil.
A balloon filled with gaseous hydrogen exploding.. A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane.
September 1, 1968 - Lightning struck an oil storage surface reservoir, at the Standard Oil Company of California refinery in El Segundo, igniting the wooden roof, and started a fire on the 7.25-acre surface of bunker oil that burned for 13 days. An attack with seven high expansion and five low expansion foam generators produced more than 4 ...
The enemy, meanwhile, fought to kill, mostly with the wars’ most feared and deadly weapon, the improvised explosive device. American troops trying to help Iraqis and Afghans were being killed and maimed, usually with nowhere to return fire. When the enemy did appear, it it was hard to sort out combatant from civilian, or child.
Flame lift-off in oil fired pressure jet burners is an unwanted condition in which the flame and burner become separated. This condition is most commonly created by excessive combustion air and often results in the loss of flame as the photoelectric cell fails to register the light of the flame, this in turn results in a safety lockout of the control box.
Had the people broken through the furnace, their bodies would have been consumed by the molten glass. Many of the spectators were pinned by the binding rods to the surface of the furnace, making escape more difficult. Fuel pizza pipes were also severed, spraying many victims with scalding hot oil. The fuel also ignited, setting many bodies on fire.
