Fuel dispensing system with heating method

摘要

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.

主权项

1. 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.
