In an example implementation, a sintering system includes optical fiber installed into a sintering furnace. A support structure inside the furnace is to support a token green object in a predetermined position and to hold a distal end of the fiber adjacent to the predetermined position. A light source is operably engaged at a proximal end of the fiber to transmit light through the fiber into the furnace. A light detector is operably engaged at the proximal end of the fiber to receive reflected light through the fiber that scatters off a surface of the token green object.

A flameless combustion oven arranges gas and air jets to directly impinge on product, being heated to substantially promote transfer of heat to the product by impingement transfer rather than by conventional radiation and thermally induced convection. In one embodiment, a set of spaced air and gas nozzles are uniformly distributed on a wall of the oven opposite the product to provide substantially uniform impingement over a surface of the product.

A batch furnace for annealing material, in particular a single chamber furnace or single coil furnace, with a furnace housing. The batch furnace has a closable charging opening, a receiving chamber for receiving furnace material, and a device for convective heat transfer onto the furnace material by a heat transfer medium. The batch furnace includes at least one fan, which is arranged in the furnace housing, at least one heating device for the heat transfer medium and/or at least one inlet for an externally heated heat transfer medium, wherein the heating device and/or the inlet is arranged directly in front of the intake side or directly behind the pressure side of the fan or circumferentially in an annular gap between the fan and the furnace housing, and a receiving chamber for the furnace material, which is arranged on the pressure side of the fan.

A heat treatment apparatus includes: a treatment chamber unit that is, inside a furnace shell, detachably fixed to the furnace shell; and a power supply portion, in which the treatment chamber unit includes: a treatment container in which a heat treatment is performed on a workpiece; a heat insulating material provided inside the treatment container; a heater that has a heating element located inside the treatment container and has a terminal located outside the treatment container; and a busbar that is provided on the outside of the treatment container and is electrically connected to the terminal of the heater, the power supply portion is provided outside the treatment container, and the busbar and the power supply portion are detachably connected to each other.

A heating furnace comprising a furnace body; an accommodation space in the furnace body, the accommodation space accommodating a work; an exhaust port; and a heat insulator provided between the accommodation space and the exhaust port, the heat insulator including a pillar-shaped honeycomb structure including ceramic partition walls sectioning a plurality of cells extending from one bottom to another bottom.

A method, apparatus and system for processing a composite waste source, such as e-waste, is disclosed. The composite waste source may comprise low-, moderate and high-melting point constituents, such as plastics, metals and ceramics. The composite waste source is heated to a first temperature zone, causing at least some of the low-melting point constituents to at least partially thermally transform. The composite waste source is subsequently heated to a second, higher, temperature zone, causing at least some of the moderate-melting point constituents to at least partially thermally transform. At least some of the at least partially thermally transformed constituents may be recovered. The method, apparatus and system disclosed may provide for the recovery and reuse of materials which would otherwise be sent to landfill or incinerated.

Embodiments of the disclosure provide a system including: an enclosure having an interior sized to enclose and the workpiece and form a vacuum and pressurized atmosphere within the interior. A plurality of thermal applicators may be in thermal communication with first and second portions of the interior. First and second thermal applicators may independently heat and cool the first and second portions of the interior. The first thermal applicator may apply a first thermal treatment to a first portion of the workpiece in the first portion of the interior. A second thermal applicator may apply a second thermal treatment to a second portion of the workpiece in the second portion of the interior independently of the first thermal treatment.

A multi-chamber type heating unit to heat a blank includes: a lower housing unit; an intermediate housing unit installed in an upper portion of the lower housing unit; and an upper housing unit installed in an upper portion of the intermediate housing unit. A plurality of intermediate housings are stacked to form the intermediate housing unit, and a heating unit to heat a blank is installed in each of the intermediate housings. Moreover, the intermediate housings are formed in the shape in which upper and lower portions thereof are opened, and an opening is formed in the front for a door to be inserted thereinto, and door sealing units provided on the intermediate housing portion and provided to seal the door when the door is closed.

The present invention relates to a plasma furnace capable of separating and discharging different kinds of molten material, which comprises a furnace body 110; and a heating portion 140 for heating the lateral discharge gate 120, 130, wherein the furnace body comprises a melt discharge portion formed through a lower portion of the melting chamber 101 provided for accommodating molten material; and at least two lateral discharge gates 120, 130 provided at different heights capable of discharging molten material.

A combustion system includes a fuel and oxidant source, a first distal flame holder body, a second distal flame holder body, and a thermal load. The fuel and oxidant source outputs fuel and oxidant. The first and second distal flame holder bodies simultaneously or alternately hold combustion reaction portions of the fuel and oxidant and/or of combustion products. The thermal load receives thermal energy from the first and second combustion reaction portions.
