Abstract
A heating element is described for a regenerative heat exchanger that is constructed as a profiled steel sheet. The aim of the invention is to produce a heating element that is resistant to acids, has anti-soiling properties and, however, has a good thermal output. To these ends, the heating element is provided with an enameling, and a fluoroplastic coating is applied to the enameled surface.
Claims7
A heating element for a regenerative heat exchanger, comprising:
- a profiled steel plate having an enameled surface;
- and
- a fluorocarbon plastic coating disposed on said enameled surface.
A method for producing a heating element for regenerative heat exchangers, which comprises the steps of:
- profiling steel coils by roll forming;
- cutting the heating element from the steel coils according to a required size resulting in a steel plate;
- enameling the steel plate resulting in a steel plate having an enameled surface;
- and
- applying a fluorocarbon plastic coating to the steel plate.
