Working principle View to the East from the parabola center One of the 63 heliostats. The principle used is the concentration of rays by reflecting mirrors (9,600 of them). The solar rays are picked up by a first set of steerable mirrors located on the slope, and then sent to a second series of mirrors (the concentrators), placed in a parabola and eventually converging on a circular target, 40 ...
The doorway is closed by two fireclay blocks at E. High temperature muffle-furnace, maximum temperature is 1,473 K (1,200 °C; 2,192 °F). A muffle furnace or muffle oven (sometimes retort furnace in historical usage) is a furnace in which the subject material is isolated from the fuel and all of the products of combustion, including gases and ...
Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash , flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste and may take the form of solid lumps or particulates carried by the flue gas.
In soldering, a thermal profile is a complex set of time-temperature values for a variety of process dimensions such as slope, soak, TAL, and peak. [8] Solder paste contains a mix of metal, flux, and solvents that aid in the phase change of the paste from semi-solid, to liquid to vapor; and the metal from solid to liquid.
Microwave oven: Reflector oven: Rotimatic: An automatic kitchen robot that bakes rotis and tortillas Russian oven: Self-cleaning oven: Solar cooker: Roaster oven An electric table or cabinet top popular in the 1950s. Large enough to bake turkeys, they had removable inserts which held the food and a lid, often with a glass insert. Tabun oven ...
A graphical example of a convection reflow oven. The oven contains multiple zones, which can be individually controlled for temperature. Generally, there are several heating zones followed by one or more cooling zones. The PCB moves through the oven on a conveyor belt, and is therefore subjected to a controlled time-temperature profile.

This keeps the lid at a lower temperature than the pot bottom. Further, little notches on the inside of the lid allow the moisture to collect and drop back into the food during the cooking. Although the Doufeu (literally, "gentlefire") can be used in an oven (without the ice, as a casserole pan), it is chiefly designed for stove top use.
