Abstract (en)
[origin: CA2936372A1] Heating element for heating gases to high temperatures, comprising at least one tube (1) arranged for the flow of gas to be heated and an electrical heating wire in the tube, which is designed for the transfer of heat to the gas flowing past the heating wire. A process heater and a corresponding heating element are provided, which permit a generation of gas temperatures up to 1000 °C or above and nevertheless have a relatively long life, which usually is at least 10 times as long as the life span of conventional heating coils when generating gas temperatures up to 1000 °C. According to the invention, it is proposed that the heating wire is formed as a heating rod (2) extending along the tube axis, whose maximum clear distance to the inner wall of the tube does not exceed a value of 10 mm over at least 80% of the circumference and/or at least 80% of the overlapping length of the tube and the heating rod.
