Need to know what type of dryer.
Yes you can... have one and plugged into regular wall plug (110v) in USA.
Different plugs are designed so that you can't plug an appliance into the wrong voltage. A dryer is usually 220-240 Volts and your standard outlet is 110-120 Volts. You can't do what you suggest.
The maximum height of the dryer plug from the floor should be 1.5m.
Not normally, the pins are in a different configuration.
in a power outlet
As long as the new dryer has the same plug configuration as the old one, just plug it into the same receptical that the old dryer was plugged into.
Plug a blow dryer in and dry it.
Probably not, the pin configuration of a 30A dryer plug should be different from a 15 or 20A A/C plug. The demand draw of a dryer is higher than that a A/C unit and would trip the 15 or 20A breaker. By putting a bigger breaker on the A/C circuit would not be a good idea either because the wire size to the A/C plug would then be under sized.
No, the two receptacles can be installed side by side.
Just immerse the spark plug in a recipient with solvent, kerosene or thinner, and use a hair dryer to get the spark plug dried again.
An electrical plug for a clothes dryer can be bought in most general hardware stores or even in some department stores with a reasonable hardware department.
