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 flying ash. [1] After the development of high-temperature heating elements and widespread electrification in developed countries, new ...
A glass melting furnace is designed to melt raw materials into glass. [1] Depending on the intended use, there are various designs of glass melting furnaces available. [2][3][4] They use different power sources. These sources are mainly fossil fueled or by fully electric power. A combination of both energy sources is also realized.
Bungs of saggars inside a bottle kiln. A saggar (also misspelled as sagger or segger) is a type of kiln furniture. [1][2][3] It is a ceramic boxlike container used in the firing of pottery to enclose or protect ware being fired inside a kiln. The name may be a contraction of the word safeguard. [4]
Heat recovery steam generator. Modular HRSG. A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).
Flame supervision device. For gas appliances, a flame supervision device (FSD) – alternative name: flame failure device (FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished. This is to prevent a dangerous buildup of gas within the appliance, its chimney ...

Reverberatory furnace. A reverberatory furnace is a metallurgical or process furnace that isolates the material being processed from contact with the fuel, but not from contact with combustion gases. The term reverberation is used here in a generic sense of rebounding or reflecting, not in the acoustic sense of echoing.
The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder.
