An embodiment of the invention provides a method wherein a simulation system having a simulator, a processor, and at least one display is assembled. A protective sheath surrounds the overwrap. The method includes coupling an assembly fixture to at least one swirler, coupling the assembly fixture to the spectacle plate such that the swirler is maintained in alignment with respect to the spectacle plate during assembly of the combustor, and attaching the swirler to the spectacle plate. The container assemblies are configured in accordance with the required volume of material to be collected or maintained in the respective container assemblies and to enable uniform head spaces despite the different volumes of materials in the respective container assemblies. The semiconductor substrate includes a resistance control structure configured so that a resistance to the current becomes higher in a central portion of the semiconductor substrate than a peripheral portion of the semiconductor substrate. The condensate is then drained out of the shield and into a condensate pan.
