A transformer designed for 220V operation will not give much more than 
220V. The voltage is limited by core saturation. You can overcome this by 
increasing the frequency, using an inverter of some kind. If it was rated 
for 220V at 50Hz then you can get (roughly) 440V at 100Hz, 880V at 200Hz, 
and so on. Or you can use an ignition coil driver circuit. In this case the 
(peak) output voltage can be very high. The insulation will probably fail 
if you try to get more than 2 or 3 kV.
