To control the temperature of the wheel space, there are two wheels separated in the gas turbine--the first-stage (the high-pressure wheel), which drives the axial compressor
, and the second-stage (low-pressure wheel), which drives the load.
stage performance is presented by the functional dependence of pressure ratio [[pi].
Ensuring 'mega capability' Dr Hans-O Jeske, chief technology officer and head of the Turbomachinery Strategic Business Unit at MAN Diesel & Turbo, stated: "As the world market leader in axial compressors
, we have closely followed the trend towards ever bigger plant complexes and have therefore constantly developed our relevant products to ensure mega capability.
In recent years, the growth in axial compressor
applications in pipeline projects has been driven by the following main factors: 1) improvements in the 3-D blade/rotor designs; 2) modern materials and blade design/manufacturing techniques; 3) a deep understanding of the aerodynamics of axial flows in axial-compressors; 4) advanced experimental methods/data analysis for the axial compressors
(such as optical measurement techniques); 5) modern/complex anti-surge systems especially designed for axial compressors
; and 6) new technologies for casing treatment, gas injection and bleeding.
6 presents (in relative characteristics) the characteristics of the axial compressor
stages with single-row and double-row bladed disks of the bladed disks under [[pi].
This includes losses from site elevation, all extractions for auxiliaries, inlet/exhaust ducting losses and axial compressor
The GE innovative high efficiency filter house is specifically designed to eliminate gas turbine shut downs for off line axial compressor
As a consequence, it has been possible to reduce the complexity (by reducing the number of total parts) of the axial compressor
and its external stator casing, which facilitates maintenance and improves operational reliability.
The new 16,000 square foot manufacturing center houses state-of-the-art tooling, designed specifically for manufacturing turbine and axial compressor
A comprehensive testing program, including the full scale test of the axial compressor
, a full-scale rotordynamic test and combustion system tests, has been completed.
x], CO and HC emissions within established limits with a variable load under actual operating conditions, it is essential to measure precisely the fuel fed to the burners and the air supplied by the gas generator axial compressor
The AS900 is configured with four axial compressor
stages, including two variable-geometry stators, a single centrifugal compressor, an effusion-cooled combustor, a two-stage high-pressure turbine and a three-stage low-pressure turbine driving a high-efficiency fan.
