combustors


Also found in: Dictionary, Thesaurus.

combustion chamber

i. The section of the gas turbine engine into which fuel is injected and burned. The combustion results in very high temperatures, which expands the air flowing through the combustion chamber and directs it onto the turbine at a uniform speed and temperature. A large amount of air passes around the walls of the combustion chamber to protect them. The three main types of layouts used for combustion systems are the multiple chamber, turbo-annular or cannular chamber, and annular chamber. Also known as burners and combustors. See can-type combustor.
ii. In a reciprocating engine, the space above the top dead center. See clearance volume.

Related to this work, the in-house CRN code was originally developed by Pratt and co-workers who also applied the software to model high-intensity combustors, e.g., [55-58].
In Application, the simulation zooming research is conducted that takes triaxial gas turbine of a certain type as physical model, establishing 2D simulation model for the combustor with Fluent, establishing system simulation model which consists of 0D component simulation models with Simulink.

However, any skeptics should remember the travail and tribulation (alluded to at our beginning here) early gas turbine developers experienced to perfect the deflagration combustors of today.
Additional complications come from the fact that the combustor pressure (and with it the pressure drop in the fuel system) depend on the engine load.
Annular combustors, while more compact than cannular combustors, are often more problematic to restore due to the fact that they have to be repaired as a whole rather then in sections.
The rates and mechanisms of metal loss are complex functions of the characteristics of the particles, i.e., composition, shape, size, and strength; of the conditions inside the combustors, such as temperature, gas or particle velocity and impact angle, gas composition, solids loading, and location; and of the characteristics of the metal, i.e., composition and morphology (Wang et al., 1990).
