Abstract
A radiant box-type electric heating furnace comprises, from the outside to the inside, a box-type furnace steel structure, box-type furnace wall panels, and a heat-insulating lining. The box-type furnace steel structure supports the entire shell and is welded to the box-type furnace wall panels. A heat-insulating lining is installed on the inner side of the wall panels for heat insulation. Furnace tubes are horizontally arranged inside the box-type furnace cavity. The medium flows from top to bottom along each row of furnace tubes. Electric heating tubes are inserted into every three or more rows of furnace tubes, with the electric heating tubes arranged at 90° angles to the furnace tubes. Multiple rows of furnace tubes are arranged horizontally, with each row spaced 1.5 times or more the tube center distance. The overall furnace structure of this device adopts a box-type structure, with the interior filled with horizontally and vertically arranged furnace tubes and electric heating tubes, maximizing the use of the furnace's internal space.
