Abstract
A propane gas delivery system having a large storage tank, a supply conduit to deliver propane gas, a first regulator and a second regulator to reduce pressure, where a secondary containment tank is provided to receive and retain any liquid propane which enters the supply conduit, whether due to overfilling of the main tank or condensation within the supply conduit, and which allows the liquid propane to reconvert into the gas phase. A float valve is provided in the outflow conduit of the secondary tank to prevent flow of liquid propane from the secondary tank in the event the amount of liquid trapped by the secondary tank exceeds its retention capacity.
