propane doesn't have smell and so it's not detectable. this can be very dangerous. this is why the parfume is mixed with it (just to give it smell).
and since it has to be cheap, it doesn't smell too nice :lol: :lol: :lol:
I dont know about the rest of the world but in the US they use Butane in lighters, butane is not propane, they are different gasses.
Butane is CH3CH2CH2CH3
Propane is CH3CH2CH3 or C3H8
Butane: also called n-butane, is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3. Butane is also used as a collective term for n-butane together with its only other isomer, iso-butane (also called i-butane, isobutane, or 2-methylpropane), CH3CH(CH3)2.
Propane: a hydrocarbon fuel gas with the formula C3H8 that is used primarily as a bottled gas for heating and cooking. Being heavier than air, if propane is in a buried pipeline, it will require a separate pump to bring a sample into a gas detector's sensor chamber.
About the Smell of Propane:
By nature, propane is clear and contains no scent at all. For safety purposes propane companies add a substance known as ethyl mercaptan to the propane fuel. Ethyl mercaptan has a strong rotten egg, or skunk-like scent, which allows the consumer to smell it in the case of a leak. If you smell something similar near your appliances and your tank it is ALSO possible that you are low on fuel. Ethyl mercaptan is heavier than propane and sinks to the bottom of the tank so when the tank is low on fuel the ethyl mercaptan odorant will become even more noticeable.
Oh, and Finally, Desel Fuel (at least as far as I know) does not have any additives to make it smell so wonderful, and yes I mean wonderful( I love tractor trailer trucks, lol) Although here in the US they do add a red dye to it to sell it as heating oil.
If you want a little bit more substantial spark, you can use a barbecue grill ignitor. You can buy replacements from a hardware store usually, or get one online. Should be around $5 or so. The sparks can be about 1 inch long if I remember correctly, and are good for making potato cannons.
They all look about the same: long plastic housing, red button with black bezel. It uses the same piezo technology in a butane lighter, only on a bigger scale, and the force required to press the button is a bit more.
On the right there's a piece of piexo crystal connected to the electrodes.
On the left there's a spring with a pin and a catch mechinism attached to the button.
When you push the button the spring compresses first, then when it's fully depressed the catch releases firing the pin at the piezo crystal and all the mechanical energy is converted into a pulse of electrical energy powerfull enough to ignite gas and even kill some insects but too small to harm you.
