You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
Yes, a 130 watt fan can be plugged into a 120 volt receptacle. The current draw will be I = W/E, Amps = Watts/Volts = 130/120 = 1.08 amps.
You can't "convert" a 120V receptacle into a 240V receptacle.A proper new 240V branch circuit complete with correctly sized circuit breakers, wiring and socket outlet is required.For more information see the Related Question shown below.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Someone has wired 240 volts into your 120 volt outlet. If you have 240 volts you need a specially configured outlet so that a standard 120 volt plug cannot be inserted. If you have this situation you would see 120 volts to ground and not neutral. Sometimes if you don't look carefully an outlet will look like the standard 120 volt variety but it isn't. One of the slots is horizontal and not vertical although there may be a small vertical split. 240 volts doesn't just magically appear. What you are describing is on purpose. If it really is 120 volt receptacle you need an electrician to put in the proper receptacle or re-wire the circuit.
The larger of the two is neutral, smaller is hot.
I'm guessing you mean 120 volt, 20 amp receptacle. Look at the receptacle. If the grounding prong is down, the flat slot on the left is your neutral. In a 120v/15 amp receptacle, this slot will be parallel to the hot slot next to it. In a 120v/20 amp receptacle, this slot will be shaped like a sideways 'T'. The reason it is designed this way is so you are able to put either a 15 or 20 amp plug into a 20 amp receptacle, but you can not put a 20 amp plug into a 15 amp receptacle.

Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.
You will burn up your appliance!!!!!

You can't. I'm not sure exactly what you're trying to do, but the way it is written is not possible. It seems you might want to use half of a duplex receptacle for 120 and half for 240. This would not be code compliant, nor would it make sense. A plug designed for 240v will not even fit into a 120v receptacle. You need a 240 volt receptacle rated for the amperage you will need. Also, an existing 120v receptacle has nothing to do with your 240v receptacle. For a 240 volt receptacle, you'll need to run 2 new 120v lines (in the same cable). The existing 120v circuit cannot be used here, even if you added another 120v circuit, because when a load uses 240v, both 120v circuits supplying the 240v must be controlled by a common disconnect (a 2 pole breaker designed for 240v circuit). My advice would be to show an electrician what you want done. I'm sure they can tell you how to make that happen.
Absoluteyl not.
Don't be stupid. No.
Chances are there is more than 1 outlet connected to the 110volt circuit you are looking to convert. So therefore the easy answer is No. The 240volt dryer circuit must be a dedicated single circuit for the dryer only.
