- A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the combustor or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the exhaust is directly fed out through the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates. To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process. Early gas turbine engines used a single chamber known as a can-type combustor. Today three main configurations exist: can, annular, and cannular (also referred to as can-annular tubo-annular). Afterburners are often considered another type of combustor. Combustors play a crucial role in determining many of an engine's operating characteristics, such as fuel efficiency, levels of emissions, and transient response (the response to changing conditions such as fuel flow and air speed).

- Kombustor merupakan sebuah komponen atau daerah dari turbin gas, ramjet, atau mesin scramjet di mana pembakaran terjadi. Kombustor ini juga dikenal sebagai burner, ruang pembakaran atau pemegang api. Dalam mesin turbin gas, ruang bakar (combustor atau combustion chamber) diumpankan suatu udara bertekanan tinggi oleh sistem kompresi. Combustor kemudian memanaskan udara ini pada tekanan konstan. Setelah pemanasan, udara melewati dari ruang bakar melalui panduan baling-baling nozzle untuk turbin. Dalam kasus mesin ramjet atau scramjet, udara secara langsung diumpankan ke nosel. (in)
- Per combustore si intende un sistema atto alla realizzazione della combustione allo scopo di produrre energia sotto forma di calore. Esistono varie tipologie di combustore, a seconda delle caratteristiche del combustibile che può venire utilizzato. In generale le dimensioni della camera regolano:
* L'altezza definisce il tempo di permanenza del combustibile all'interno della camera
* La larghezza è determinata in base a calcoli di natura fluidodinamica, posti ad ottenere una appropriata distribuzione di temperature all'interno della camera di combustione
* La profondità determina generalmente le potenzialità termiche del combustore (it)
- 燃焼器(Combustor)とはガスタービンの構成要素の一つで燃料を圧縮された空気と燃焼する装置である。レシプロエンジンやロケットエンジンの燃焼室(Combustion chamber)に相当する。 (ja)
