ABSTRACT:
In a vapor recovery system, vapors are drawn into a combustible fluid storage tank as the fluid is pumped into a vehicle fuel tank. The storage tank need not have provision for the aspiration of a carrier gas to remove the vapors. At a threshold pressure, a pressure sensing switch is tripped to pass vapors to a combustion chamber. An ignitor ignites the delivered vapors. A flame detector senses the presence of burning gases. A relay is responsive to the flame detector and latchs open a timing mechanism. If no flame is detected, the timing mechanism causes an interruption in the flow of vapors. A flame arrestor prevents a flame flashback in the vapor line. A temperature sensing switch interrupts the flow of vapors in the event it senses flame flashback. An auxiliary disposal circuit is operable to process high pressure vapors due to storage tank refilling.
