DME gas through the regultor problem.
DME gas through the regultor problem.
(OP)
I am currently setting up a combustion experiment and I encountered a problem with a fuel I am using.
For this set up, I am using DME gas and thread type is POL.
When DME is released through the regulator, it gets really cold that it almost freezes over in few minutes. (This is beacuse of latent heat of vaporization within the bottle, and for regulator - isentropic expenstion of the gas, cools and joule thomson cooling effect)
Thus, this needs to be fixed.
For this issue, the one proposed method is putting heaters near the regultor so it does not freeze
Other method is placing a flexible line between DME bottle and regulator. Flexible line from the bottle to the regulator (In line heaters)
Heat up these line with the heater is or put the flexible line in the hot bucket of water is suggested.
Since the bottle connection doe not involove the electricity, this option is came out to be most relevent method.
However, I wonder would there be better way to deal with such a problem.

RE: DME gas through the regultor problem.
If you must evaporate liquid outside the bottle, you'll need sufficient heat transfer area to do so. They do make heated regulators for this purpose.
