Tunnel kilns are used for the continuous firing of catalysts, ceramics, and other products in a hydrogen-protected atmosphere.
The furnace body includes parts such as the furnace shell and lining, where the shell is welded from steel plates and sections, featuring a fully sealed structure; the lining is constructed from lightweight clay bricks, insulation bricks, and refractory fibers, etc. This equipment is suitable for continuously firing catalysts, ceramics, and other products in a hydrogen-protected atmosphere. The tunnel kiln should be used in a well-ventilated room with air humidity ≤ 85%, and there should be no conductive dust or corrosive gases around the equipment.
