Vaporizing cold propane

Most propane storage tanks store propane in a liquid state. The regulators that are used on internal combustion engines incorporate a heat exchanger. Drawing the heated coolant of the engine in to warm the propane. If the generators are order to run on propane should be on the engines all ready. Unless you are going to the extreme north should not have any problem.

Thanks for the informative response.

Still wondering about what temp will cause tank problems. If the temperature is 40 below and I am drawing propane from the tank it will get even colder due to heat of vaporization and I believe propane stops vaporizing (above ambient pressure) at around -44F.

Just realized my 1st question was incomplete. Assume 300 gal tank, 10% full. Using 2 gallons per hour.

If you are operating in minus 40F deg below you will be struggling with the last 10% in the tank.

Liquid vaporisers should be installed in low temperature locations. Presumably you would need to install automatic ignition for the vaporisers also as they are emergancy backup so would only be fired up when needed.

Propane should vaporize above minus 42 C.

At my house in Vermont, the gas company simply installs 2 300 gal. tanks so you hopefull will never need to use the last 20%

Someone on the team suggested a fine system for your purposes, recently.
