The PVC pipe threaded into to my pressure tank broke off at the threads. The tank has no water in it, and I need to release all the pressure out first.
How can I remove the piece of pipe still in the tank opening? Can I heat it with a torch?

The best way to do it is to pick up an extractor such as this one from Lowe's or use an internal pipe wrench as mentioned by @DIY75 in the comments. Regardless, if the bladder's stop is visible at the opening, make sure you get a tool short enough to do so without damaging it.
If you're trying to get by without it, my recommendation would be taking an old set of needle nose pilers and use a torch (MAPP will make it quicker) to heat the tips. Insert them into the hole, open to melt the PVC, then turn to unscrew the broken bit. Make absolutely sure you're steady and DO NOT over-insert if you choose this method.
You appear to have already cut or melted a slot in the broken pipe stub.
Insert a screwdriver and twist in the slot to bend part of the broken pipe away from the iron female threads. Bend until it either breaks off, or you can grab it and pull it out.
Bending the "upper" side in this picture away will make removal by rotating what's left counterclockwise easier, as you'll be pulling rather than pushing what's left of the plastic pipe fitting. Once you have a little space you can also slip additional tools in from the end to pry the plastic away from the iron.
