If you have 3 ph delta 220, you will be able to supply 220 1 ph for the
kilns by connecting between any two hots, but there won't be any 120
volt to neutral (delta doesn't have a neutral, and the voltage from any
hot to ground won't be 120 volts).

Not true. Phases A and C to neutral yield 120V, phase B to neutral yields
208V. Delta panels *do* (or can) have 120 volts. My shop is wired three
phase delta and has 5 wires, four conductors ( A, B and C phase, plus
neutral) and one ground. One avoids using the B phase for 120V, obviously.
