Lpg Gas Stove Flame Is Soft And Noisy

I have a gas stove , it had problem with the flame , mine is yellow instead of blue so it left the smoke onpot?

I don't know how to fix your stove.
But if you are asking how to clean the pot, use bicarbonate/baking soda. And a damp cloth, or nylon scrubber.

Why the flame of LPG on stove does not make fire in the gas cylinder itself?

The container pressure is one factor, but actually it is the absence of oxygen in the cylinder that inhibits combustion.

Conversely, if you are using a propane tank (instead of acetylene) with oxygen for cutting metal it IS possible for the flame to flash back into the cylinder. Use of a flashback valve prohibits this.

Your LPG gas stove at home is giving a yellow flame. What can this mean?

Gas stoves are popular with homeowners because they provide efficient heat transfer with precise heat control. They heat cookware with flame from a burner. A properly adjusted gas stove burner burns with a blue flame. But if the burner is out of adjustment, the gas flame will be yellow.Needs More AirGas burners burn blue if the ratio of fuel to air is correct. A yellow burner flame is a symptom that the burner is not getting enough air for complete combustion of the gas. Correcting this problem involves adjusting the burner’s air shutter to admit more air, something that an experienced do-it-yourselfer can do.Open StovetopIf you want to fix the problem of a yellow flame yourself, allow the stove to cool, remove the top grates and lift up the stovetop to expose the burner piping. On most stoves, the air shutter is just behind the burner gas valve. It is a sliding plate or tube that covers the burner air vent. Loosen the set screw that keeps the shutter from moving. Turn the burner on fully and slowly open the shutter until the flame turns blue. Retighten the set screw, turn off the burner, lower the stovetop and replace the top

Why is the flame in a gas stove so much less bright than in a candle?

Candles are meant to give light, and humans have done their best to make candles that give as much light as possible. As others have said, the light is emitted from glowing particles of incompletely combusted wax. If you put anything above the candle to try to make it hot, you’ll see a lot of fine soot get deposited on it.A gas stove, and I’m assuming you mean a town gas or natural gas stove rather than a petrol stove, is meant to give heat. The burners are designed, using engineering principles, to make the most heat possible, as efficiently as possible. Efficient combustion means no particles of carbon in the flame.The best way of producing light from heat is the use of an incandescent mantle, found in camping gas lamps, Coleman lamps, Tilley lamps and formerly in street gas lamps all over the world. the rare earth oxides that form the ceramic mesh of the mantle convert infra-red (heat) into visible light, giving a bright glow from a relatively small flame.

Why does my gas stove show orange with the blue flame?

Sodium burns with an orange flame. Sodium salts, including table salt, are everywhere and tiny amounts will give the characteristic orange flame. Cheap soaps and most detergents contain sodium salts of fatty acids. Cleaning your stove top will deposit enough of these salts for the flame to burn orange.The above is separate from the orange flame caused by incomplete combustion. If this occurs, you’ll get a smoky flame. If you get a smoky flame from a gas appliance for more than a few seconds, switch it off and call the relevant maintenance service. A smoky flame from a gas appliance is caused by incomplete combustion and could lead to the production of carbon monoxide, an exceptionally dangerous and toxic gas.

What colour should the flame be in a gas oven? What do the colors indicate?

It should be a blue flame.  In a perfect world the gas would, under heated conditions provided by the existing reaction that’s occurring, react with oxygen.  Since matter is neither created nor destroyed the oxygen and gas molecules would become water and carbon dioxide during the course of the reaction and everyone would be happy.  Perfect combustion is extremely difficult to achieve however, though your stove burning a blue flame is coming extremely close.  Since we don’t get perfect combustion reactions in a stove, instead of only producing water and carbon dioxide it will also produce some carbon monoxide and some carbon soot.  If the flame is blue it is producing only a very, very small amount of carbon monoxide or soot (enough that they are virtually undetectable).Yellow/orange flames indicate that the combustion reaction has become much less complete, therefore producing more carbon monoxide and carbon soot. This can indicate several things.  Firstly, there may be some materials, like bits of food, that have fallen onto or near the burner and are now burning off.  It may also indicate that the flame is not receiving enough oxygen, or too much gas or too little gas is being burned at once.  If the small holes that the gas flows through on the burner become obstructed, it can also alter the flow-path of gas and how air (oxygen) is entrained into the flame thereby affecting its ability to achieve close to perfect combustion.If the flame is any other color it indicates that some type of other substance is being burned.  I’m not sure what that substance might be, but perhaps an ingredient in a cleaning agent may (I doubt it though) be the culprit.  I know that copper will burn green, and some flammable metals will burn white, and pure ethanol actually has a clear flame.  I don’t think that you’ll see an exotic colored flame in a stove though.  If you see blue you’re good, if you see yellow perhaps try cleaning around the burner especially if there’s a build of up soot or burned food around it.  If it continues to burn yellow I would contact the gas company and the appliance’s manufacturer.

What temperature does a gas stove flame go to?

The LPG gas burning in your stove is a Saturated Hydrocarbon which gets sufficient oxygen for burning. That's why it burns blue. Paraffin wax in candles are Unsaturated Hydrocarbons. That's why they don't get sufficient Oxygen for burning and cause a bright yellow flame to form and release Carbon Dioxide on combustion. The reason why a candle is brighter than an LPG stove is because of the fact that Blue light is of much higher frequency than Yellow light emitted from the candles. That means it has a much lower wavelength than the yellow light. Lights with lower wavelengths do get reflected properly and are absorbed by other materials in a phenomenon called the Photoelectric Effect. That's the same reason why they use red lights as stop signals. So that it can rip through thick mist and fog. Bottom line is, lower wavelength(as in case of blue) equals dimmer light. Higher wavelength(as in case of yellow) equals brighter light.

What is the reason of back fire in burner of lpg gas stove while spark light ignites?

When you first turn it on from cold look at the flame. It should be equal height all around and the color of the flame should also be the same all the way around. If the burner has been removed and cleaned it might be installed at an angle. Grab it while cold to see it it's positioned firmly.
If the flame color is off it is air flow. if the flame is higher or lower then the burner is in wrong. See if moving it around a little changes anything. It doesn't take much more than a pot boiling over to clog the jets. A pin or toothpick will clean them.
