To operate a turbine at optimal efficiency, the actuation fluid must be extremely hot. The part of a gas turbine that is subjected to the most stress at high gas temperatures and large straining force is the casing. Fouling is the most common deteriorating issue in gas turbines, and it can lead to a loss of airflow, pressure ratio, and efficiency.
The gas turbine compressor is made up of four horizontal split casings. The four components are the inlet casing, compressor discharge casing, exhaust frame assembly, and diffuser casing. Lines related to the compressor section, such as cooling and sealing lines, and surge control lines, should be removed before disassembling the casings.
The upper halves, atomizing air, purge air, and gas fuel manifolds should all be removed. The front and after casings, which may or may not be included in the bell mouth, are removed first, followed by the CDC (compressor discharge casing). Before the bell mouth can be removed, the Bell-housing mouth must be removed first. They ensure that as little turbulence as possible enters the compressor.
When cold temperatures and excessive moisture content combine, the gas turbine inlet filter system and the turbine itself can be harmed. Damage can occur in seconds, but the consequences can be long-lasting and costly for operating performance and maintenance expenses.
The third is the exhaust plenum and stacks linked to the exhaust output section of a gas turbine to take exhaust gas. In the exhaust plenum, there is the first wall. A seal attachment component on the first wall is in thermal contact with the external shell of the first wall and is used to attach an annular flex seal to it.
Finally, a gas turbine casing defines the number of segments, each of which is supported by several radially projecting struts. It marks the boundary of a piece of the turbine flow duct. At least one of the struts interposed between the deformable struts is relatively rigid, allowing relative thermal expansion between the heated segments and the supporting casing.
Prismecs works with a wide range of engine parts and materials for purchase. For decades, they’ve been the market leader in all types of casing and their operations.
