CONVEYOR OVEN HAVING AN ENERGY MANAGEMENT SYSTEM FOR A MODULATED GAS FLOW

摘要

A conveyor oven (20) has a modulating gas valve (30), which raises and lowers the thermal output of a burner (50) that heats the oven. A bypass line (35) passes a minimum amount of gas to prevent the burner (50) from completely shutting down during periods while the oven remains above a threshold demand for more heat. Electrical isolation is provided between temperature controlling devices (32) to prevent an electrical feedback, which might otherwise prevent a complete shut down of the oven during hazardous conditions.
