A flare stack that preferably comprises a burner assembly, an exhaust stack, an housing, and a fuel line. The burner assembly burns a fuel to generate therm al energy and combustion byproducts. The exhaust stack is cooperatively associated with th e burner assembly to direct the thermal energy and combustion byproducts away from th e burner assembly. The housing at least partially defines a fluid-receiving chamber i n thermal communication with the exhaust stack. The fluid-receiving chamber has a heat - transfer fluid disposed therein. The fuel line is in fluid communication with the burner assembly to deliver fuel to the burner assembly. At least a portion of the fuel line is in thermal communication with at least one of the exhaust stack, housing, or heat- transfer fluid to permit fuel in the fuel line to absorb thermal energy before reaching the burner assembly In one embodiment, the burner assembly includes a pressure-variable burner t o increase the rate of fuel consumption of the burner in relation to the pressure in th e fuel line. In the preferred embodiment, the housing has an inlet and an outlet formed therethrough in fluid communication with the fluid-receiving chamber. The inlet permits heat- transfer fluid to flow into the fluid-receiving chamber to absorb thermal energy from the exhaust stack, and the outlet permits heat-transfer fluid to flow out of the fluid-receiving chamber.
