Abstract When ensuring the normative limit of heat gas transmitted to main pipelines by means air cooling devices transmission compressor station, modes parallel operation fan motors device system are considered. At same time, a comparison was made methods for adapting factors affecting energy-efficient operating modes. As result, based on mathematical model combustion mode through gas-air devi...

determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

and other process equipment in a secure web-based environment and allows users to; • Run your process more efficiently. • Improve your operating margins. • Avoid unnecessary shutdowns. • Improve your maintenance management decisions. GAS TURBINE PERFORMANCE is subject to degradation over time. When gas turbine engines are run, they become fouled with airborne contaminants such as oil, pollen, s...

The instantaneous mass flow was measured during the intake and discharge processes of a reciprocating gas compressor (1)*. The purpose of these measurements was to identify the mechanism which caused a loss of adiabatic and volumetric efficiency that could not be accounted for by valve flow losses. The measurements were made wi ·th square-edged orifices and fast response differential pressure t...

Abstract The gas booster station of a steel works has experienced excessive bearing failures since commissioning over two decades ago. This was designed with redundancy, allowing for automatic switch-over between fans. Bearing were observed, on average once every 15.7 days, instances where both fans simultaneous downtime. Booster resulted in regular downtime, preventing Coke Oven Gas (COG) tran...

This two-part paper describes a compressor redesign program for improving efficiency, lowering sound emission, and cost. Part 2 indicates how sound and discharge pulse were reduced through research conducted on transmission loss of plastic vs. steel manifolds and discharge pulse modeling using four pole parameters Common reciprocating compressors utilize steel flapper valves and a Cylinder Head...

The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...

The gas flow estimation is crucial for the proper operation and monitoring of turbocharged (TC) engines with a torque structured engine control unit (ECU). This paper presents mean value models developed for modeling gas flow over the compressor, the turbine and the wastegate (WG) in a TC gasoline engine not equipped with a hot film air-mass flow meter (HFM). The turbine flow ...
