High-temperature heating apparatus

A heating apparatus for generating heat for industrial processes, the heating apparatus comprising:

• at least one heating unit connected via connecting electrodes to an electrical unit, the at least one heating unit being configured to heat fluid streams entering the heating apparatus along a longitudinal axis from an inlet temperature to an outlet temperature, wherein the at least one heating unit comprises a first end that is connected via one of the connecting electrodes to a first electrode of the electrical unit, and a second opposite end that is connected via another one of the connecting electrodes to a second electrode of the electrical unit,
• wherein the at least one heating unit further comprises at least one heating element, wherein the at least one heating element comprises an inlet end that is in electrical connection with the first and second ends of the at least one heating unit, and is configured to receive the fluid streams having the inlet temperature, and
• wherein the at least one heating element further comprises an outlet end that is configured to be heated above the outlet temperature.
