Preheater for oil burner - has at least one fuel conducting duct making contact with electrical heating system

摘要

The conducting line section is surrounded closely esp. by the heat transmitting heater, at least in the heating region of the preheater. The heater (5) at its side has such a cross section, that its surface line, at least at one place (6) is designed as a straight line. One heating system (2) at least is provided, at one level casing surface, formed by at least one such straight line (6) in the continuous flow direction. The heating system (2) makes close thermal contact with the largest part of the casing surface. USE/ADVANTAGE - Preheating of heating oil before nozzle in burner nozzle assemblies. Simple as possible construction. Easily produced and ensures effective thermal coupling in fuel conducting line(s). Creates possibility of short burner nozzle assemblies.
