The air going through the furnace is absolutely isolated from the pilot-- If not, don't you think it would just blow it out every time it ran??
There is nothing about forcing air through your ducts that will blow up a furnace....worst thing I can think of, is humidity collecting in the duct, and mold or mildew growing in them....blowing all over your house, but no explosions--
I am glad you said it. I have no idea how a furnace works but it seems like the air being heated is not in direct contact with the flame or gas for obvious reasons.
