Yes, a blown fuse can cause your furnace to not turn on. Check the breaker box and see if any of them have tripped.
I'm not sure why your furnace would shut off after a power outage but first check your breaker in the breaker box to make sure it is in the on position. If this is not the problem remove the cover on furnace and look for a red reset button on the pump. Press this button and hold for a second or two and you furnace should restart. If however it shuts down again you have other problems and will need a furnace repairman.
The equation for amperage is I = W/E, Amps = Watts/Volts. The amperage for the furnace would be, Amps = 15000/240 = 62.5 amps. So to answer the question, yes a 100 amp breaker with a #4 copper conductor will be sufficient to operate a 15 kW furnace. A 70 amp breaker will work but it is cutting the edge a bit too fine as you don't need the furnace to trip off during the winter months (northern hemisphere) if you are away from your home for an extended period of time.
It's in the basement. Turn on the light switch behind the dryer, walk past the furnace, stay to the left of the water heater, and you'll eventually see the breaker box on the wall in front of you. For heaven's sake, do be careful.

The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
Breaker boxes do not have fuses associated with them unless the main disconnect is independent from the breaker box. If that is the case both fuses have to be the same in the main disconnect that protects the breaker box.
The BREAKER box is in the factory.
