Except that the scale is wrong and the limits prevant it from happening. The amount a space a firebender would need to fill with heat to create those effects, and the amount of heat they would need to fill it are beyond the abilities even of a firebender with the power of Ozai and Azula combined during noon AND Sozin's commet.

Even if they could fill that much space with that much heat, they couldn't control it. Real physics don't work that way. By the time a firebender put that much heat in the air moisture, it wouldn't do what you say, but would explode instead. This is because it couldn't hold the extreme amount of heat required. So eventually it would release it. Kaboom! It's an effective bomb, but that's it.

Also firebenders can only control the heat part. The can't prevent the air or moisture in te air from exploding, and they can't make it hold more heat. They can only put heat into that area.
