Can-annular combustion chamberCombustion chambers must be designed to ensure stable combustion of the fuel injected and optimum fuel utilization within the limited space available and over a large range of air/fuel ratios. The combustion chamber design depends on the application and requirements in each case.
Can-annular combustion chambers are a combination of can-type and annular combustion chamber. All flame tubes have a common secondary air duct. The aerodynamic properties are inferior to those of an annular combustion chamber. The connectors between the individual flame tubes adversely affect the ignition behavior.
Can-annular combustion chambers are suitable for large engine and - for mechanical reasons - for engines with high pressure ratios. Development costs are lower and the volume smaller than with a can-type combustion chamber.
