I supposed DGT can replace spark plug for glow plugs to misdirect, but that
would still not explain the temp spike.
Sparks are the only mechanism that can bring H2 temps that high and then
quickly back down again. Glow plugs will not result in a temp spike.
When you look at the end plates of DGT reactors, you will notice that the
thermocouples are very close to the spark plug. A series of sparks would
quickly raise the temperature of the H2 gas in the vicinity of the sparks,
which is also where the thermocouples are. Then a second later, the hot H2 gas
diffuses and the temps are down again. Hence a temp spike.

After surfing the different glow plugs on the web, I believe that Jojo is
correct, that what is shown in the pictures offered by DGT are probably spark
plugs.
However, might there be misdirection in DGT's pictures? Would a glow plug
screw in place of the spark plug in their reactor? DGT could have put the
spark plugs in their reactor for the pictures, while they normally use glow
plugs in those positions. The spare spark plug on the table was obvious and
suspiciously left in the open.
Another possibility is that DGT found that the glow plugs were wearing out
too quickly and they modified their reactor for a different type of heater that
would have greater life. Since they were left with the tapped glow plug holes,
they plugged the holes with the spark plugs. The spark plugs are never shown
connected, but everything else is shown connected.
The comment from W&M about DGT having trouble with the glow plugs not lasting
long enough goes with what Jojo observes for a glow plug.
I am not convinced either way.

And only if you want to waste your money. Like I said, they don't last
very long when used continously as would be the case if DGT were using these to
heat their reactors.
A heating cartridge would make more sense for heating.
I tried using glow plugs in my first generation reactors with so-so
results. They tend to overheat and melt your ingredients. Hard to control
heat output. They are designed to heat fast and furious. Controllability is
not an issue for their intended application as Diesel engine preheaters as they
are fired only for a few seconds. but, even in their intended application in
diesel engines, they are one of the more frequently failing items.

PS. Those pictures are definitiely spark plugs. No question about it.

using a glowplug for heating is very natural, since it is very resistant,
cheap, and easy to find.
