Abstract: An electrically powered furnace and related methods may include an electrically powered furnace having an output of at least one megawatt with a control system; a furnace housing comprising one or more housing walls at least partially defining an interior volume; a plurality of heating zones within the interior volume; and a plurality of heated tubes extending in the interior volume. A method may include providing the feed to the electrically powered furnace; and algorithmically adjusting the output of the one or more heating elements for each of the plurality of heating zones to heat the feed to a desired temperature while maintaining temperatures of the one or more heating elements within predetermined parameters.

Abstract: An electrically powered furnace may include a furnace housing and heating elements extending in the furnace housing. The furnace also may include heating tubes extending in the interior volume, and each of the heating tubes may define an interior passage positioned to receive and heat the feed as the feed passes through the interior passage. The heating tubes may be positioned in the furnace housing to receive heat radiated from the heating elements, and the heating tubes may be arranged in one or more of at least two rows or at least two columns and such that each of the heating tubes is substantially equidistant from three or more of the heating elements. A method may include supplying a feed to the heating tubes, heating the heating tubes via the heating elements, and heating the feed via as the feed passes through the heating tubes.
