i think that might be the key difference, the fact that the king's chamber is in an elevated situation in relation to it's entrance (unlike the tombs in the valley of the kings) that from a practical point of view it needed the air shafts to dispel 'bad air' (which generally rises) while work proceeded and then the funeral arrangements could take place, which may or may not have included the burning of oils and/or herbs (?)
their inclined angle up through the pyramid would be to draw the air upward like a chimney rather than a two way flow
and their north/south orientation perhaps serving a secondary ceremonial purpose either to the gods Nut (sky) or Shu (wind)
Since the "air passages" weren't open to the outside, I find this unlikely.
Also, "bad air" would be far more prevalent in underground tombs than in raised ones.
CO2, CO are both heavier than air. So is smoke.

Everyone knows of the famous Baghdad battery. Making electric cells using (citric and other) acid isn't really very hard and has been used for thousands of years eg to plate jewellery. The fact that no smoke residue is present inside the Pyramids lead us to the question of how the inside was lit if not by torches or lamps.
Mirrors have been suggested but I personally do think lightbulbs aren't really that hard to make. We know the ancients had glass and metal working skills. The ancient Egyptians knew how to blow glass;

From your own link:

Decorative glass was very difficult to produce and was quite rare. In ancient time glass was made from sand quartz and the ancients were using some very complex chemistry to both create and color the glass. They simply whetted beads, figures or bottles of any shape since they couldn't blow spherical forms.
Perhaps I can suggest you read your own sources?

Making a "crude" light bulb is the next step. We have to remember that our ancestors had as much capacity for thought as we do, I think more so in some ways, because the current attitude relies on our discoveries to base theories upon. We are constantly discovering new ancient civilisations and constantly pushing the date back for both civilisation and modern man because of new discoveries. It's one thing to rely on evidence to make theories but it's another to rule out possibilities because of lack of evidence. Some evidence simply hasn't been discovered by us yet.
It is certainly reasonable to not consider "possibilities" that we know aren't actually possible.
Of course, they used oil lamps to light their work. We have hundreds of examples from all over the time period covering Ancient Egypt.
If everyone used oil lamps, where are the light bulbs (which they couldn't make)?
