Not sure about flames but a kettle of boiling water poured over the crank end can help. Aluminium expands more than steel so have the pedal pointing forward, the spanner pointing back with just a few degrees of up so when you stand on the spanner it'll move 1/2" or so in the desired direction, then pour the boiling water steadily over the crank end and once done stand on the spanner. I usually have the front wheel against the wall so the bike doesn't move.
