Default Propane @ Generators

I would like to thank you for all of your input with this site !!! Can you tell myself and others the proper way to feed a generator with propane or lp gas ?? Do you need 1 regulator or 2 as well as pressure and water column problems.

Iam in the middle of cooking but you will need a pound to ounces regulator.Then a demand regulator and a shut off solenoid.Will get back to you on the system later.It is not that much to it.

Simplest thing is to call a dealer for propane carburetors etc and give your application so they can tell you what you need. IMPCO and CENTURY are two major brands of this stuff. Both of these companies sell a combination regulator and vaporizer for liquid cooled engines which takes the propane from tank pressure liquid to low pressure vapor and incorporates the demand regulator. I have also used these without hooking up the radiator water circuit when drawing vapor instead of liquid propane. There might be something cheaper for vapor only, but we have quite a few vehicles on propane so there are some extra vaporizers around. The smaller versions are used on forklifts etc. and the larger ones on 500 + cubic inch displacement trucks so there is quite a selection available on the market.

On a vehicle the sequence is from tank to electric solenoid valve to vaporizer(regulators included) to gas mixer (carburetor). One suggestion which was made is to stop the engine by shutting off the gas solenoid valve and letting it run out of gas so there is no liquid propane left to vaporize and potentially leak a lot of vapor out into the engine and its surroundings. Like any gas equipment, prompt attention to any gas smell or other evidence of leakage is very important. That being said, I would much rather have propane fueled engines sitting around the house than gasoline fueled ones.

See thread on main Spark Arcs board about propane.
