Worn or damaged filter grids. Replace all grids with holes and recharge filter.
Baking powder is not a gas, but it does make a cake rise by releasing carbon dioxide into the batter through chemical reaction.

Pass the mixture through filter paper. The salt water will pass through leaving the chalk behind in the filter paper.
copper will not 'spark' causing ignition of the powder. Steel can produce a 'spark' causing the powder to ignite................
Something is allowing the DE to pass through the filter - probably a hole in one of the filter pads or a damaged manifold. You can take out the filter pads and visually check them. A hole will be fairly obvious.
Umm...a solid chemical that's been ground to a fine powder?
The thermal decomposition of baking powder is a chemical change.
I"m not sure what a Doughboy is, I'll take a stab that it is a filter system. I have added DE through the pump intake. I put a little at a time in a bucket and dilute it then pour it into the skimmer. As the water flows through the filter, the DE powder adheres to the 'fingers' that hang down in my filter allowing the filter to filet out more minute particles than the clothe 'fingers' alone.. Some also use DE powder in conjunction with sand filtration to improve filtration. I think it causes backwashing more often, then the DE powder ends up in the yard or wherever the backwash goes. Good Luck
