The can-type combustion chamber

The can-type combustion chamber

  • The can-type combustion chamber is typical of the type used on turboshaft and APUs. Each of the
  • can-type combustion chambers consists of an outer case or housing, within which there is perforated stainless steel (highly heat resistant) combustion chamber liner or inner liner. The outer case is removed to facilitate liner replacement.
  • Older engines with several combustion cans had each can with interconnector (flame propagation) tube, which was a necessary part of the can-type combustion chambers.
  • Since each can is a separate burner operating independently of the other cans, there must be some way to spread combustion during the initial starting operation.
  • This is accomplished by interconnecting all the chambers. As the flame is started by the spark igniter plugs in two of the lower chambers, it passes through the tubes and ignites, the combustible mixture consists of an undivided circular shroud extending all the way around the outside of the turbine shaft housing.
  • The chamber may be constructed of heat-resistant materials, which are sometimes coated with thermal barrier materials, such as ceramic materials. The annular combustion chamber.
  •  Modern turbine engines usually have an annular combustion chamber.
  •  the annular combustion chamber also uses louvers and holes to prevent the flame from contacting the side of the combustion chamber.
