A plate conveyor belt, and a furnace with such a conveyor belt, for transporting a material web which is to be continuously thermally treated using a gaseous tempering medium. The plate conveyor belt includes conveyor belt segments connected together in an articulated manner and each of which has a flat cover plate with a contact surface for the material web to be treated. The cover plate has openings for conducting the gaseous tempering medium, which can be conducted through the material web. The openings in the cover plate are arranged corresponding to the transport of the material web which is as wide as possible, and edge-side openings of the cover plate at least along a longitudinal face of the plate conveyor belt can be blocked from conducting the tempering medium via a wall-shaped blocking element in order to thermally treat a narrower material web.

Disclosed is a firing furnace for firing an electrode of a solar cell element, which is provided with: a transfer member, which transfers a substrate having a conductive paste applied thereto; a heating section, which heats the substrate and fires the conductive paste; and a cooling section, which cools the heated substrate. The furnace is also provided with a heating means for heating the transfer member. Specifically, at the time of firing the electrode paste using the wire-type firing furnace, since a wire is fired at a temperature substantially equivalent to the ambient temperature of the heating section, deterioration of yield due to having the electrode damaged by a deposited material of the metal component of the conductive paste is suppressed, said deposited material being deposited on the wire, and the wire-type firing furnace can be continuously used.

A finish heat treatment apparatus for an iron powder. Raw iron powder is placed on a continuous moving hearth and continuously charged into the apparatus. In a pretreatment zone, the raw iron powder is subjected to a pretreatment of heating the raw iron powder in an atmosphere of hydrogen gas and/or inert gas at 450 to 1100° C. In decarburization, deoxidation, and denitrification zones, the pretreated iron powder is subsequently subjected to at least two treatments of decarburization, deoxidation, and denitrification. In the pretreatment zone, a hydrogen gas and/or an inert gas serving as a pretreatment ambient gas is introduced separately from an ambient gas used in the at least two treatments is introduced from the upstream side of the pretreatment zone and released from the downstream side so as to flow in the same direction as a moving direction of the moving hearth.

A plant for recovering metals and/or metal oxides from industrial process waste, in particular oil product refining waste, comprises a furnace; a feed line connected to a main inlet of the furnace and configured to feed the furnace with a solid waste containing metals, in particular in oxide form; an outlet line, connected to a solid phase outlet of the furnace and configured to draw a metal-enriched solid phase out of the furnace; the furnace is a belt conveyor furnace having a belt conveyor closed in a loop with a substantially horizontal configuration and having a top face, which receives the waste to treat and conveys it between two longitudinal opposite ends of the belt conveyor furnace respectively provided with the main inlet and the solid phase outlet.

The invention relates to a device for treating container blanks for a container treatment installation. The device comprises a furnace for heating the container blanks. A planar drive system has a base element and a plurality of movement devices for transporting the container blanks. The plurality of movement devices are movable independently from one another relative to the base element. The container blanks can be moved through the furnace by means of the plurality of movement devices.

A method for ventilating an oven configured to cure a binder bonding mineral fibers placed on a conveyor, the oven including, in series on the path of the conveyor, an inlet, a plurality of heating chambers and an outlet, the method including a procedure in which a predictive model for estimating an amount of pollutants is used.

Methods and apparatuses for continuous, large scale, commercially viable production of nanoforests. A roll-to-roll process passes a flexible substrate, including fibers and fabrics, through a furnace. Precursors are introduced in a growth zone in which a vertical or horizontal nanoforest of nanotubes or nanowires is grown on the substrate. Sensors and actuators with feedback control are provided for parameters such as substrate speed, substrate tension, furnace temperature, precursor flow rate, nanoforest thickness, and nanoforest. The furnace is preferably enclosed for environmental and safety purposes. The feed roll and take-up roll are disposed in housings can be attached to the furnace via airlocks, which enables rapid loading and unloading of the rolls using techniques well known in the industry while maintaining furnace conditions. The furnace can encompass flattening rollers and a second growth zone to enable manufacture of orthogonal nanoforests comprising a vertical nanoforest grown on a horizontal nanoforest.

A method and an apparatus method for producing direct reduced iron (DRI) from iron ore using biomass as a source of reductant and as a heating source of the iron ore and electromagnetic energy as a further heating source in a furnace having multiple zones. The zones include a preheat zone and a reduction zone between an inlet for briquettes of iron ore and biomass and an outlet for direct reduced iron. The method includes counter-current movement of (a) briquettes of iron ore and biomass in a direction from the inlet to the outlet and (b) combustible gases in an opposite direction in the furnace.

This application relates to a conveyor and a baking device. A traction rope may bring an electrode plate to move in a transport space. The traction rope may be of high flexibility and can more smoothly bring the electrode plate to move in various complex environments such as an arcuate oven, thereby effectively avoiding derailment or jamming of the conveyor in the oven and conveying the electrode plate more smoothly in the oven.

The invention relates to a conveying system for conveying a material to be conveyed along a conveying path. The conveying system includes a conveying chamber in which the conveying path is arranged. At least one component of a conveying mechanism for conveying the material to be conveyed is arranged outside the conveying chamber. The conveying mechanism includes a traction drive having at least one traction element by means of which carrying elements can be moved in order to convey the material to be conveyed. The carrying elements are arranged in the conveying chamber and protrude through a through-opening out of the conveying chamber. Inside the conveying chamber and/or in the region of the through-opening, the surfaces of the carrying elements are at least partially provided with a thermal insulation material.
