A glass heating furnace is disclosed. The glass heating furnace allows glass to be heated up more uniformly, which reduces effectively the formation of the thermal stress marks on the glass. The glass heating furnace uses primarily a roller power module to control the rollers to displace reciprocatively, allowing the glass to be heated up uniformly and reducing significantly the formation of the thermal stress marks in the heating process of the glass, through the reciprocative displacement of the rollers. A glass is made by the glass heating furnace. The glass displaces in a chamber of the glass heating furnace along an S-shaped moving path or an 8-shaped moving path.

A sintering furnace can have a housing, one or more heating elements, and a conveying assembly. Each heating element can be disposed within the housing and can subject a heating zone to a thermal shock temperature profile. A substrate with one or more precursors thereon can be moved by the conveying assembly through an inlet of the housing to the heating zone, where it is subjected to a first temperature of at least 500 C. for a first time period. The conveying assembly can then move the substrate with one or more sintered materials thereon from the heating zone and through an outlet of the housing.

An auxiliary heating means for improving the melting efficiency of melter kettles used to melt thermoplastic pavement marking materials. The auxiliary heating means includes a tube assembly through which thermoplastic material received from the bottom of the melter kettle is transferred to the top of the melter kettle. The tube assembly comprises an odd number of tubes having augers therein. The tube assembly is coupled to a side portion of the melter kettle and located within a heat chamber through which hot combustion gases from a combustion chamber at the bottom of the melter kettle flow and transfer heat into the tube assembly. The heat chamber comprises an extended portion of a heat chamber that surrounds the melter kettle.

The invention relates to a multi-level furnace for thermal treatment of the material flow which has at least two process chambers arranged one above another, each providing at least two level floors, and is equipped with one or more transfer devices for transferring the treated material flow from an upper process chamber to a lower process chamber. In order to separate the two process chambers in terms of gas flow, the transfer device has means for forming a material column in the transition region between the upper and the lower process spaces, wherein said means for forming a material column comprise at least one conveying unit or at least one chute, and the at least one conveying unit or at least one chute also forms a material removal device for the upper process chamber and/or a material input device for the lower process chamber.

The present disclosure concerns a system for curing a wet coating of a coated substrate, the system comprising: a curing room having a curing room inlet and a curing room outlet, the curing room being configured to receive the coated substrate being introduced at the curing room inlet thereof along a first displacement axis, the system comprising a conveyor assembly for conveying the coated substrate through the curing room along a second displacement axis transverse to the first displacement axis, wherein the system further comprises a gas catalytic IR system, provided in the curing room, for producing an infrared radiation to partially cure the wet coating while the coated substrate is in the curing room. The disclosure concerns also a corresponding process.
