The combustion chambers are enclosed in a removable shroud that covers the entire burner section. This feature makes the burners readily available for any required maintenance. Can-annular combustion chambers must have fuel-drain valves in two or more of the bottom chambers. This ensures drainage of residual fuel to prevent its being burned at the next start. The flow of air through the holes and louvers of the can-annular system is almost identical to the flow through other types of burners. Reverse-flow combustors are mostly of the can-annular type. Reverse-flow combustors make the engine more compact. Pratt & Whitney use a can-annular-type combustion chamber in their JT3 axial-flow turbojet engine. Moreover, General Electric and Westinghouse use this type in their industrial gas turbines. Advantages of can-annular types are as follows:

Mechanically robust
