3 phase kiln

A friend of mine purchased a kiln at auction and didn't realise that
it was wired for three phase power. Is it possible to rewire it for
single phase without replacing all the elements.

It may be possible depending on the voltage and configuration. Are the
elements connected to the power as the letter "Y" or Greek delta (triangle)?
In delta, each element gets the rated line voltage 208 volts on a 120/208
system and in Y each element gets 1/square root(3)=.577 of the line voltage,
120 volts on 208 systems. If this is the case, you could connect two elements
in series to run on a 240 volt single phase system. If you have an even
number of elements, you will be OK. If you supply the info from the nameplate
we could be more specific. Usually there will be ratings:voltage, current,
power and connections: a little diagram or table of terminal numbers and
voltage.
