Abstract
The novel segment electric in-line process electric heaters heater designed to
heat various fluids analyzed in this work. The complete electric heater consists
of several hollow cylindrical segment heating elements. The segment heating
elements can vary positioned in relation to the fluid flow. The total power of
the segment process heater is equal to the sum of the power of all heating
segments and is 0.756kW. Volumetric air flow variations in the amount of
0.001m3s-1, 0.002m3s-1 and 0.003m3s-1. The heating elements are positioned in
the three combinations in relation to the direction of the fluid flow. The
comparative numeric analysis, conducted for this work, has the goal to
determine the influence of the arrangement of segment heaters on the overall
energy efficiency of the segment electric heater. In order to verify the results of
the numeric simulations carried out and experimental investigations of the
segment electric heater.
