Abstract
Embodiments of a heating system maintains the temperature of a fuel additive (e.g., AUS32) at and/or above freezing temperature to avoid crystallization. The heating system can form a fluid circuit with one or more coaxially arranged sleeves disposed about hoses that transport the additives. The fluid circuit can also include a central compartment that encloses a flow meter. A fluid heater couples with the fluid circuit to provide heating fluid, e.g., to the central compartment. The heating fluid disperses throughout the heating compartment and into the sleeves, thereby direction heating fluid in thermal proximity to the hoses and other components that handle the fuel additive.
Claims22
A method of heating for a fuel dispensing system, comprising:
- receiving at a flow meter surrounded by an enclosure a fuel additive from a storage tank, the fuel additive flowing from the flow meter to a hose extending coaxially through an entire longitudinal length of an elongated sleeve that extends from the enclosure to a nozzle, the nozzle being configured to dispense the fuel additive;
- and
- heating the fuel additive flowing in the hose.
A fuel dispensing system, comprising:
- a flow meter configured to receive a fuel additive for delivery to a nozzle configured to dispense the fuel additive;
- a heating element;
- and
- a coaxial fluid pathway that includes a hose extending coaxially through an elongated sleeve, the hose having an outer surface, the elongated sleeve having an inner surface, and a gap being defined between the outer surface of the hose and the inner surface of the elongated sleeve, the hose being configured to receive the fuel additive from the flow meter for flow through the hose and delivery to the nozzle, the heating element being configured to provide heat in the gap that heats the fuel additive in the hose.
A fuel dispensing system, comprising:
- a flow meter configured to receive a fuel additive for delivery to a nozzle configured to dispense the fuel additive;
- a heating element;
- a coaxial fluid pathway that includes a hose extending coaxially through an elongated sleeve, the hose being configured to receive the fuel additive from the flow meter for flow through the hose and delivery to the nozzle, the heating element being configured to provide heat that heats the fuel additive in the hose;
- and
- a compartment enclosing the flow meter, the heating element being configured to provide heated fluid into the compartment that flows therefrom into the elongated sleeve.
