Get a certified technician to work on gas. He will have to change the orifice, possibly the gas valve.
You can just refill the propane tank. It is more difficult to do something like change a gas generator to a propane generator.
YES, you could use those little tanks for a fireplace (providing you have the proper adapter and gas regulator. BUT it won't work for more than a couple hours. The BTU output is to great for such a small canister and the pressure drop causing carbon monoxide (from the fireplace).
The weight will never change. Allow the volume can change depending on the temperature. The hotter it is the more propane liquid will expand. This is the reason for only filling propane tanks to 80%.
It is a chemical change
Check with your gas appliance service company. With most gas burning appliances, it is necessary to change the size of the jet. IF the maker has a correct sized jet, it could likely be converted to NG.
You don't have to change or remove the converter unless the converter is stopped up.
Propane burning is a chemical change. The propane reacts with oxygen. New compounds are the result of the process.Let me add a little more information to this. Propane stored in the tank is in liquid form under pressure (actually an equilibrium of propane gas in the top of the tank, and liquid propane in the bottom). When you open the valve, the gas escapes into the hose and goes to the burners.As the gas escapes, some of the liquid propane evaporates into gas form.The change from liquid to gas is a physical change.
Yes, Propane burns hotter.
it is a chemical change. this is because when you burn anything it is going to be a chemical change
it is quite safe, propane gas does not explode. you should know how propane smell and should leave the house once you smell it. Gas doesn�??t burn as hot as oil therefore propane isn't looking particularly economical. although propane is cleaner.in addition it is so much quieter, there is no oil smell. if you looking to save money do not change otherwise propane is a very good choice
Change out the gas flow orifice size to propane and adjust the gas valve.
