how does flame arrestor used in Hydrogen gas lines work?

it is the same as a flashback arrester used on oxy-acetylene welding bottles - it is essentially a one way valve that closes if there is any rapid change of pressure on the outlet side i.e. a flame.

The flame will heat the air molecules above it.These gas particles being free to move in any direction will move in the direction which has least opposition to it's motion .This is because the air above the gas has a lower density and hence is sparcer than the air below it .also the flame particles have a higher energy (due to their temperature)they tend to stay as far away from each other as possible .This creates a lower density of air around the flame .This low density sir will be pushed up by the surrounding air of higher density due to buoyant forces.Due to both these regions the flame has to move up

The electrolysis of water with the o2 and h collected in seperate test tubes a lit match will ignite the hydrogen...POP! and a matchstick that has been blown out but still has a hot ember will burst into flame in the oxygen.

By itself, water is an unreactive substance by nature. So you cannot separate oxygen and hydrogen from the water molecules. However, there is only one ay in hich this canbe done: electrolysis.\n\nIt involves the passage of an electric current into a liquid, which naturally conducts electricity. Electrodes are used to pass the electric current. At both the electrodes, gases are evolved, depending upon the liquid.\n\nSome acid or alkali should be added to water for the evolution of gases, namely hydogen and oxygen at the electrodes.\n\n\n\nIt can be mass-produced, but the process is too costly. An application could be to use hydrogen in hydrogen powered cars to replace the more polluting petrol powered cars. \n\nMoreover, oxygen is also obtained by the fractional distillation of liquid air. It involves cooling air by decreasing the its pressure by placing them in special containers, capable of bearing atmospheric pressure. This process is more economical, compared to electrolysis. Liquid oxygen and hydrogen is used to power rockets in order to propel them into space. This process for the production of liquid oxygen and hydrogen is mass produced nowadays to power rocket and hydrogen powered cars. \n\nThanks

Hi. Usually to minimize pressure variations in a home's water system. Fire extinguishers, aerosol cans, Coleman stoves, etc. all use them to store potential energy.

Suppose that you have gas under low pressure, with an electrostatic field applied.  If an atom of the gas is ionized by some means, it will drift toward the negative electrode, with a speed that increases the farther it falls (just like a rock under gravity).  At some point, it will collide with another atom, and by the time it does so, it will - or will not -- have acquired enough energy from the electrostatic field to ionize the target atom.  If it does, the current will increase; if it doesn't, it will kick the target and lose much of its own energy in the process.  If the target is ionized, the process can accelerate in a chain reaction, and the current will increase rapidly until it runs into some sort of limit which is typically imposed by the external circuitry.  Bottom line: if the pressure is too high, the mean free path is too short for ionization to occur; if it is too low, there are not enough gas atoms to carry the current.

First of all, the "ballast" is not a transformer, but a shock coil and is used to create an extra current  just in order to ionize the gas inside (a mixture of neon-if neon lamp, or others like krypton , argon and so on). That's why when you apply a shock to both sides of the tube (with the tube being tide in parallel withe the wires) and the filaments inside are burned or not you can start ionizing  the gas. The ionized gas is current conducting so it by-passes the circuit from the wires, and also starts illuminating.\nDfriend :)

because it contaminates the color of the flame and produces a differently colored flame then say a hydrogen flame which is colorless

Good question.  The flame converts wax into chemicals that evaporate into the air. Here's how it works:\n\nThe heat from the flame melts the wax into a liquid.  The liquid is drawn up the wick by a process known as capillary action.  The liquid wax is heated by the flame until it turns into a gas.  The gaseous wax combines with the oxygen in the air.  This chemical reaction produces many chemicals, but since wax is a hydrocarbon, (it contains mostly hydrogen and carbon, just like other flamable chemicals such as gasoline and wood) the byproducts are mostly water (a combination of hydrogen and oxygen) and carbon dioxide (a combination of carbon and oxygen).  In the heat of the flame, both water and carbon dioxide are gasses and float away into the air.  That is where the wax goes when the candle burns.

It has hydrogens all around the outside if it which are going to have a partial posative charge on each so they will readily bind to other substances in the air and effectivley trap them.

Fuel, Heat, Oxygen - Also known as the traditional fire triangle.\n\nFuel - Something that can be burned\n\nHeat - The fuel must be heated to the point that it can burn.  Yes, it's true that once the fire starts it can and does generate it's own heat, but if that heat were removed somehow (i.e. the application of water), the fire goes out.\n\nOxygen - Fire's need oxygen to burn.  This is either the oxygen in the air, or from the chemicals that are burning, such as oxidizers.  If you were to interrupt the oxygen with say another gas, such as CO2 (as in a CO2 fire extinguisher), or blanket the fuel with dry chemical, a fire blanket, foam, etc., the fire goes out.\n\nThere is actually a fourth component to fire, and that's the chemical chain reaction itself.  Adding this forth component changes the fire triangle to a fire tetrahedron.  If the chemical reaction is halted, say by adding Halon, FM-200, FE-13, or some other gaseous fire extinguishing agent, the fire goes out. (and NO, halon does not "suck" all the oxygen out of the air, there's much more to it than that.)\n\nThat all being said, I like hatingmsn's answer that you may also need a permit!  HEHE... good one and may actually be a fifth component!

I have never heard of the idea of burning "Water" in a carbureator.  Actually (not that I am a car expert), I have never heard ot burning anything in the carbureator, isnt that suppose to mix the fuel-air before it gets into the engine for combustion?\n\nAnyhow, when gasoline (or any Hydrocarbon) is combusted/"burnt" one of the products is water.  It doesnt make much sense to burn somethat to produce extra energy if it is already being produced anyway as a byproduct.\nYour not going to get anything extra out of trying to burn water, more like than not, you'll loose a lot of energy by having to heat it up...stealing energy away from other expanding gasses.\n\nOne thing though, if you put water (steam) into your engine, you will be displacing fuel and Oxygen which ordinarily would be combusted.  Having less fuel-air in the engine to cobust would mean less energy would come out of each "cycle" of the engine.  As long as your not very demanding on your engine (not trying to tow a boat up a big hill), this might well be OK, you will use less gasoline and therefore get better "Gass" mileage....in theory.\n\nOf course there is a way to seperate the Hydrogen (and Oxygen) out of water, actually, there are a lot of water to do this, but every way requires more energy input than you will ever get out of combusting the Hydrogen back with the Oxygen.  The basic laws of thermodynamics tell us this is a no win situation and any attemp to try to electrolysize the water using the alternator (a popularly spread theory) is bound to fail, since in essence, your trying to make a perpetual motion machine.  The alternator is powered by the engine, the engine is powered by the fuel.  If the fuel your using is made by the alternator, you have got a cycle going that wont last long.

Someone has used a gasifier and captive-piston engine to make a one-moving part alternating-current generator. The piston is magnetized and the coils are in the body of the cylinder. The trapped air in the cylinder at each end of the piston acts as an air shock to eliminate rebound and impact damage. No sensors needed. No make and break circuit. The voltage drops to zero at the end-points of travel of the piston. Search on this and you can probably find the same one I saw. I think this is where they got the idea for those new shake-up LED flashlights.

Water is what you get when you burn hydrogen. After combustion the bonds between the H and O atoms are so strong, that no more burning happens.\n\nWhen you burn any molecule that contains hydrogen, like CH_4,\nnatural gas, the same thing happens. All the hydrogen ends up in water molecules.

Separating the Hydrogen and the Oxygen from regular water is a simple grade school physic's experiment. I have included a link to a experiment page. Now whether it is illegal in Great Briton, I do not know. Now why we don't use it, you would have to ask the major car manufactures that question. The technology is not new, there has been powerful fuel cells floating in outer space for almost 4 decades. The problem with hydrogen as a fuel, is that if it expands uncontrollably you will have one big explosion on your hands.

I don't know the specific name for it, but, in telecommunications, there is a certain type of plastic used for insulating wires.  This insulation is known as self extinguishing, in that, as heat is applied to it and it gets to the point where it starts to try to burn, it releases some kind of gas that extinguishes the combustion that is beginning to take place.
