Turbine Diagnostic Services, Inc.

		The turbine generator skids sit in the lower shipping containers. The containers have a swing open door with grate covered louvers to allow for the air to exhaust from the container after cooling the oil and ventilating the unit. The container has one of these doors on each side. The insulation of the turbine casing can be seen though the door.
The exhaust elbow attaches to an expansion joint and is supported with brackets off of the turbine lower container. The upper container supports the exhaust silencer and the stack. The exhaust elbow is insulated for personnel protection. The air piping can be seen in the picture connecting the air skid to the supply manifold to each unit container. The air is supplied from the high pressure 475 psig skid and tanks to the supply manifold through a two back pressure regulators.

		Access to each container is attained through the swing open doors on each side of the turbine. The turbine exhaust expansion joint can be seen on the left side of the insulated turbine housing. The compressor inlet plenum is located on the right side of the picture and has a plexiglass viewing window in the side for viewing of the air stream. This will allow for verification that there is not excessive air inlet water fogging and saturated water droplets in the air stream. The turbine exhaust thermocouples on the right side of the turbine casing have been increased to six to allow for temperature spread monitoring to provide indication of degradation of the turbine volute contained within. The air inlet plenum connects to an expansion joint at the top that allows flexibility of the lower turbine skid position to the position of the air inlet duct contained in the upper container.

			The combustion can is located on top of the turbine casing and seen on the opposite side of the turbine casing in the picture. The foreground of the picture contains the air relief valve and the connection of the air to the atomizing air supply header. The combustor fuel nozzles located on the top of the combustion can are set up for liquid fuel operation. Due to the low 4:1 pressure ratio of the machine, any liquid can be burned as long as it can be pumped. The combustion system requires annual maintenance and more so than the rest of the turbine generator skid. Access in the floor of the upper container allows for access to disassemble the combustor and also the turbine section of the machine where the compressor and turbine impellers can be accessed for the tri-annual hot gas path inspections. A beam is installed in the upper box with a trolley that allows for rigging of components in the lower container.

The combustion can and manifold piping is shown in this picture. The access above can be seen to allow for the rigging of components from above. The sound insulation of the lower container ceiling can be seen in the picture.
		The fuel stop and control valves are located on the left side and the oil system components located on the right side of the container.

This picture was taken from the generator end of the container next to the oil filters viewing toward the turbine. The generator is on the right with the generator output lead routing flex joint. The upper generator compartment contains four busses. One for the generator neutral which grounds to the frame of the machine and container. The other three busses are for the output leads which must route to the electrical services building. These busses were installed to provide an easy method of landing the 500 mcm cables (4 per phase).

The sound insulation can be seen lining the inside of the shipping container. New gauges have been installed to allow for the local monitoring of systems. New transmitters have been installed to allow for closer monitoring of the control parameters in the new TurboNet Dash 1 control system.

This is a picture of the compressor inlet as viewed through the plexiglass viewing window. The shaft can be seen to the right of the picture.

Air enters the bell mount opening just to the left of the shaft. All hardware in the air stream is locked with wire or a locking device.
