Gas turbine engine combustor, method of supplying air to the combustor, and dome assembly

摘要

A combustor (16) for a gas turbine (10) includes a dome assembly that facilitates extending a useful life of the combustor in a cost-effective and reliable manner. The dome assembly includes a dome plate (142) and a heat shield (170) coupled to the dome plate. The dome plate includes an impingement baffle (148) and an opening extending therethrough and sized to receive a fuel injector. The impingement baffle also includes a plurality of cooling openings (164) in flow communication with the heat shield that direct cooling airflow for impingement cooling and film cooling of the heat shield.
