I bought a 1994 spectrum tanning bed and can't get it to come on its a 220 volt bed and I have 220 volts going to bed but it will not come on I can hear a humming noise but the bulbs will not light up

This will most likely be as simple as just replacing the blown bulbs. If too much power goes through most bulbs they act like a fuse and 'Pop'. Looks like you've been lucky and the blown bulbs have stopped the 220 volts from damaging other parts of the tanning bed.

This seems to be a Tanning Bed, so let's move you from the category Cars and Trucks!

All questions need a simple 'make model (what is is)', at the beginning of all questions please.

Was your furnace electric or gas? If it was electric it was probably 220 and should work (although testing with a volt meter would be a great idea)

If the bed is a 220 volt, you can only use a 220 volt outlet.
If the bed is 110/220 you should check the web for specs and wireing.

I have 1987 SCA-24 series 1 wolffsystems tanning bed how do I change the bulbs or where can I get owners manuel?

no, voltage is not the issue, what is the amperage you need. If you need more than you have, then you could have 2000 volts and it will not work. Also your taking AC to AC, or DC to DC. There's a big difference in what you need for each.
look up Ohms law for for the calculations needed for voltage vs amperage using one socket.
good luck
