An analytical device has an oven arrangement (1) with an oven (2), an insulation system, a ventilation system and a housing. The ventilation system has a first convection system that uses natural convection, arranged to keep the housing cool, as well as a second convection system that uses forced convection, arranged to reduce the temperature in the oven (2). In particular, the analytical device is a component of a Karl Fischer titration instrument.

The invention relates to a charging installation (1) of a metallurgical reactor, with a cooling assembly (4) disposed for cooling a reactor side of the charging installation (1). In order to facilitate the installation and maintenance of a heat protection shield in a charging installation of a metallurgical reactor, the cooling assembly (4) comprises a plurality of cooling panels (10), each cooling panel (10) comprising at least one coolant channel (12). The channel (12) is formed as a groove in the base plate (11), which groove is covered by a cover plate (13) mounted on the base plate (11).

A sidewall for a metallurgical furnace and a metallurgical furnace having the same are described herein. In one example, a sidewall of a metallurgical furnace is provided that includes an outer wall, a hot plate and a buckstay. The hot plate is coupled in a spaced apart relation to the outer wall. The buckstay is mechanically coupled to the outer wall and the hot plate. The buckstay includes a buckstay web extending from a buckstay flange. The buckstay web includes a first end coupled to the buckstay flange, and a second end mechanically and movably coupled to the hot plate.

The invention relates to a heat protection assembly (2, 30) for a charging installation (1) of a metallurgical reactor. In order to increase the lifetime of a heat protection shield in a charging installation of a metallurgical reactor, the assembly (2, 30) comprises a plurality of heat protection tiles (31.1, 31.2, 31.3, 31.4) disposed adjacent to each other along a surface The assembly further comprises a plurality of heat protection panels (10, 110), each panel (10, 110) comprising a common base plate (11, 111) to which a plurality of tiles (31.1, 31.2, 31.3, 31.4) are connected, which heat protection panels (10, 110) are configured to be mounted on the charging installation (1) adjacent to each other.

A high temperature vacuum furnace including a prefabricated tongue-and-groove, low-mass insulation ring assembly hot zone, resulting in decreased energy costs and increased energy efficiency, faster heating and cooling cycles, and expedited maintenance capability resulting in lower maintenance costs. Decreased time of a workpiece in the furnace improves production turnaround and lowers energy costs for each heat treating cycle. Furnace manufacturing is also easier and less expensive compared to prior art vacuum furnaces. A bottom support structure replaces the prior art metal support ring resulting in an approximately 80-85% weight saving in the furnace hot zone. This reduces the time and energy required to heat and cool the furnace components and workpiece.

A heater is provided to heat a metallic workpiece as a heating treatment target. In a heat treatment chamber, the heater and the workpiece are disposed. A shielding member is disposed between the heater and the workpiece inside the heat treatment chamber, and provided to be capable of shielding radiation of radiation heat from the heater to the workpiece.

A thermal insulation structure is disposed at an exterior of a chamber of a heating device. The thermal insulation structure includes a heat conduction layer, a heat storage layer and a reflection layer. The heat conduction layer is adapted to conduct heat from the chamber to the heat storage layer. The heat storage layer is adapted to store heat. The reflection layer is adapted to reflect radiation heat back to the chamber, whereby a temperature of the chamber could be kept at a constant so as to reduce heat dissipation of the chamber.

A flame holder system includes a support structure configured to support a plurality of burner tiles within a furnace volume. The support structure includes a frame supporting a support lattice. A number of burner tiles are arranged in an array on the support lattice. The support structure is configured to be assemblable without tools inside the furnace volume, using components that are sized to fit through an access port in a wall of the furnace.
