The outgassing occurs quickly above the boiling point of HCN. As I showed earlier those rooms used a heater and blower. The heater was to keep the temperature in the room between 30C and 35C (above the 25.6C boiling point of HCN). The blower was to penetrate small spaces. At the 30-35C temperatures, the graphs on Berg's page there show that the full outgassing occurs in under 1/2 hour:Turnagain wrote: ↑Sun Sep 08, 2019 12:36 amBlake121666 wrote:I'm not talking about the air recirculation for penetrating clothing.

Then we have:Method for generating the necessary heat for the vaporization of poisonous substances for gases used for pest control.
Then:The air was heated before it passed through the granules in the basket. The heated air drove the hydrocyanic acid out of the granules...
Obviously the heated forced air was first and foremost a means of expediting the complete outgassing of the Z-B. Your conclusion that the heated forced air was only used to penetrate tightly woven cloth is spurious, Blake.After at least an hour, the operator could begin the venting phase...
On the right is a graph with the blower and on the left is a graph without the blower.
The curves are of the 5 corners and the center of the room (the center of the room is the bold line). The corner nearest the Zyklon is the first to have its graph rise to a maximum at full outgassing. As you can see,with the blower the gas distribution settles down to be uniform pretty quickly. Without the blower, you see that only the corner nearest the Zyklon reaches its maximum fairly quickly and the other corners only rise as the gas meanders through the clothing.
The process takes over an hour because it takes that long to ensure that everywhere that nits could be have received a sufficient amount of HCN to kill them. That means that the HCN needs to penetrate to very very small dimensions.
Such is of course definitely, without any doubt, NOT the case in the human gassing scenario. There's no penetration of anything required at all. What would be the reason for a blower? I'm not saying that the process would not go slightly faster WITH a blower. It just simply is of no necessity in the human gassing scenario. For the very large rooms that were the alleged gas chambers, a fan system such as for these little rooms is an absurd idea.
EDIT: BTW, hydrocyanic acid is HCN in water. Your highlighted text is technically incorrect. The temperature evaporates the HCN GAS out of the hydrocyanic acid - which had been adsorbed onto the carrier material - and into the air. The fan does indeed help in this - but is of secondary significance compared to the temperature in the room and the thinness of the Zyklon layer. The evaporation happens much more quickly when there isn't anything blocking it - such as other Zyklon granules. The Kula basket distributes the Zyklon thinly. And I'm sure the Zyklon tossed in the windows was splayed out a bit as well.
