How can gas burn underwater?
A gush of gas can form a flash flame; this flame then breaks, resulting in a small flamelet that spreads on the water surface. Increasing the leakage pressure enhances the burning process and the flamelet gradually disappears.
Can gas pipeline catch fire?
Fire characteristics of gas pipeline in cities and towns Gas is flammable and explosive. The minimum ignition energy of natural gas is 0.28 mJ, flame propagation speed is 0.67 m/ s, minimum ignition temperature is about 537 , and explosion limit is 5\% 15\%.
How does a gas pipeline explode?
Negligence, carelessness, and violations of Occupational Safety and Health Administration (OSHA) workplace safety regulations are among the common causes of pipeline explosions. Pipeline explosions can also occur when heavy equipment performing excavation work, such as backhoes, strikes a pipeline.
How can a fire start in the ocean?
The ocean-surface fire was caused by a ruptured underwater pipeline, according to the state oil company Pemex.
Can a gas fire burn underwater?
The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch. The gas must be supplied at a high enough pressure to overcome the pressure exerted by the water.
Do flares stay lit underwater?
Yes flares can be lit underwater! For a flare to burn, you need oxygen, heat, and fuel. While water would be a problem for a normal fire to stay alight underwater due to lack of oxygen, this isn’t true for flares because the fuel AND an oxidizer is stored in the flare as a solid mass.
Does fire burn underwater?
Originally Answered: Can fire occur underwater? Yes. If you supply fuel and oxidizer. There are also flares that burn underwater.
How does fire work underwater?

Can an ocean freeze?
Ocean water freezes at a lower temperature than freshwater. Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. It can be melted down to use as drinking water.
Can a fire be lit underwater?
Was there a fire under Mexico’s Gulf of Mexico pipeline?
Mexico’s state-owned oil company said a fire caused by a rupture in an undersea gas pipeline in the Gulf of Mexico is over, but videos showing efforts to put out what appears to be an underwater caldron of fire live on. Video Player is loading. This is a modal window.
Why is there a fire at the bottom of the ocean?
The fire itself is happening at the surface as Simon George, a professor of organic geochemistry at Macquarie University in Australia, explains. “The fire was caused by methane and probably other wet gas components (ethane, propane, etc.) igniting at the ocean surface after leaking from the pipeline,” he told CNET via email.
How long did it take to extinguish the Qatar oil pipeline fire?
The state oil company then began to “close the interconnection valves in the pipeline, extinguishing the fire and the gas emanation” to control the leak by 10.45am, more than five hours later.
What caused the California oil rig fire?
“The fire was caused by methane and probably other wet gas components (ethane, propane, etc.) igniting at the ocean surface after leaking from the pipeline,” he told CNET via email.
