Now, if you decide to install a 240V appliance, it will need 240, so it would not run in a 110V 30A plug even if you are feeding both legs.
A 240V appliance could suffer damage if plugged in in this manner. Examples are a cooktop, water heater, AC, etc.
A purely 240V appliance (i.e. one that does not rely on the neutral or have some internal 120V circuitry) can not be harmed by this; it just won't work at all, as it has 0V applied to it and is effectively the same as being disconnected.
Most appliances that are 120/240V would also just not work properly. Typically the controls and timers would operate, but the heaters and motors and such don't have power. I'd be rather surprised if that caused damage, but I suppose anything is possible in theory.
