Abstract (en)
[origin: EP0208241A1] A heating unit for heating great amounts of flowing gas, such as a process gas to be heated to a temperature of about 300-500 DEG C, e.g. for drying products. The heating unit consists of a number of units mounted in side by side relation and each comprising a great number of series connected heating wires (16) suspended in a frame mounted in the flow duct of the gas and adapted to apply its high voltage of from 1 to 36 KV, the series connected heating wires having such a resistance that an effect of not less than 1/2 MW is dissipated in the plant. As a result a heating unit is obtained which compared to its output is encumbered with exceptionally low costs of construction and operation, particularly in areas with an inexpensive electricity supply due to water power.
