A system includes an engine case for a gas turbine engine defined around a longitudinal axis. An access opening is defined through the engine case for access from outside the engine case to a space inside the engine case. A combustor is housed in the space inside the engine case. The combustor includes an inner annular wall and an outer annular wall radially outboard from the inner annular wall. The inner annular wall includes a first rail on an upstream end thereof. The outer annular wall includes a second rail on an upstream end thereof. The first and second rails each include a respective access portion configured to receive line replaceable injector components from through the access opening of the engine case into the first and second rails to form a combustor dome of the combustor.

Disclosed are a burner assembly and a gas stove. The burner assembly includes a burner, a gas distribution disk mounted on the burner, and a flexible metal seal ring located between the burner and the gas distribution disk, and the bottom of the gas distribution disk is provided with a first fitting surface, the top of the burner is provided with a second fitting surface, the flexible metal seal ring is provided with a first surface and a second surface opposite to the first surface, the first surface is in seal-fit with the first fitting surface, and the second surface is in seal-fit with the second fitting surface of the burner. The gas stove comprises a panel, a bottom shell and the burner assembly. The burner assembly can prevent gas leakage during operation of the gas stove, thereby improving the safety of the gas stove.
