What is 2 stage combustion chamber?

What is 2 stage combustion chamber?

Typically, propellant flows through two kinds of combustion chambers; the first called preburner and the second called main combustion chamber. In the preburner, a small portion of propellant is combusted, and the increasing volume flow is used to drive the turbopumps that feed the engine with propellant.

Can tubular type?

A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. 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).

What is combustion chamber in aircraft?

A combustion chamber is where the fuel is burned at constant temperature with air and gas turbine, where the air is expanded to generate electricity.

What is the use of combustion chamber?

A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the firebox which is used to allow a more complete combustion process.

What is the second stage in the combustion process?

Air staging, or two-stage combustion, is generally described as the introduction of over-fire air into a boiler or furnace. Staging the air in the burner (internal air staging) is generally a design feature of low NOx burners.

What type of combustion system is there in gas turbine?

Type of combustion chamber. The diffusion and premixed flame are two main type of combustion, which are using in gas turbines. Although there are different types of combustors, but generally, all combustion chambers have a diffuser, a casing, a liner, a fuel injector and a cooling arrangement.

What kind of combustion chamber is a can?

Can Type Combustion Chamber : Can combustors are self-contained cylindrical combustion chambers. Each “can” has its own fuel injector, igniter, liner, and casing. The primary air from the compressor is guided into each individual can, where it is decelerated, mixed with fuel, and then ignited.

What does a combustion chamber do in a gas turbine?

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.

Which is the best description of an annular combustion chamber?

Annular Type Combustion Chamber : Annular combustors do away with the separate combustion zones and simply have a continuous liner and casing in a ring (the annulus). There are many advantages to annular combustors, including more uniform combustion, shorter size (therefore lighter), and less surface area.

What’s the difference between a can and an annular combustor?

Like the can type combustor, can annular combustors have discrete combustion zones contained in separate liners with their own fuel injectors. Unlike the can combustor, all the combustion zones share a common ring (annulus) casing. Each combustion zone no longer has to serve as a pressure vessel.
