11. It also required a gas-fired heater to simulate combustor inlet conditions. 12. Increasing the overall pressure ratio of the compression system raises the combustor entry temperature. 13. In 1989, CFMI began work on a new, double-annular combustor . 14. A combustor must contain and maintain stable combustion despite very high air flow rates. 15. Early gas turbine engines used a single chamber known as a can type combustor . 16. Afterburners are often considered another type of combustor . 17. During the whole process, the operating conditions are relatively uniform for the combustor . 18. An open circuit gas turbine cycle has a compressor, a combustor and a turbine. 19. The combustor , or burner, was primitive by the standards of modern turbojet engines. 20. However, a cannular combustor can be more difficult to maintain than a can combustor.
