Abstract:
<span>One of the main reasons of the performance degradation of gas turbines is the axial compressor fouling due to air pollutants. Considering the fact that the fouling leads to high consumption of fuel, reducing of the axial compressor’s discharge air pressure and increasing of the exhaust temperature, thus designing a compressor degradation detection system will allow prevent such issues. Many gas turbine plants lose power due to dirty axial compressor blades, which can add up to 4% loss of power. In case of power plants, the power loosing could be observed by less megawatts produced

During hot days, gas turbine power output deteriorates significantly. Among various means to augment gas turbine output, inlet air fog cooling is considered as the simplest and most costeffective method.

In addition to cooling the inlet air, overspray can further enhance output power by intercooling the compressor.

The airfoil has a difficult time doing this reliably and well and so does the compressor. When it does, it allows for amazing performance of the engine in terms of power and efficiency.

Abstract:
To achieve at a more precise designing procedure in axial-compressors as well as a higher pressure ratio value, a comprehensive understanding on the flow aerodynamics and the governing phenomena is required. Existence of these complicated phenomena e.g., simultaneous production of supersonic and subsonic flows, shock-boundary layer interaction, unique incidence phenomenon, etc, makes it difficult to analyze the flow in the transonic compressors. One of the methods which is useful in the modeling of the phenomena occur in the compressors is investigating the flow in the blade to blade passage.

Abstract:
Inlet air filters are widely used to remove solids and liquid droplets from the ambient air before it enters the compressor of a gas turbine. Clean inlet air provides many advantages: Less corrosion of the compressor and of gas-path hot parts, such as the turbine, decreased compressor fouling, less erosion of the compressor bladeThese in turn prevent deterioration of output and heat rate, and reduce maintenance costs. Compressor fouling is caused by the ingestion of substances that deposit and adhere to blade surfaces, resulting in reduced aerodynamic efficiency and decreased available output.

Full text
Abstract:
Prior attempts to develop a generic Parametric Emissions Monitoring methodology for combustion turbines, particularly low emissions units, have failed due either to the reduction of a complex problem to too few degrees of freedom or the brute force reliance on regression analysis. Field test data collected by the research team clearly illustrated that a successful PEMS model will need to incorporate multiple zones to account for pilot fuel versus pre-mixed combustion, and changes in air/fuel ratio at the flame front. The information reported herein shows that, ideally, the PEMS model should re

Abstract:
This report describes field trial demonstration and validation of a Gas Turbine Predictive Emissions Monitoring System (PEMS) using engine data from Siemens Energy SGT-300 gas turbine compressor drivers at SoCalGas Blythe Compressor Station, California, USA. The advanced PEMS model results are compared with CEMS data taken from process analyzers measuring emissions in the gas turbine exhaust. After the necessary corrections on emissions for water content and oxygen content in the exhaust, the values for PEMS and CEMS show good agreement across a wide range of operating conditions.

Abstract:
To develop the requisite air flow rate, the turbocharger must operate at a relatively high efficiency. But as important, the system pressure losses must be minimized to optimize turbocharger operating flexibility so that the turbine can produce sufficient power to operate the turbocharger compressor. The relationship between the various pressures and pressure losses throughout the turbocharged engine system, the turbocharger overall efficiency, ambient conditions, and the required turbine inlet temperature for sustainability is rooted in fundamental thermodynamic principles.

Abstract:
Existing expansion-type starters at pipeline compressor stations require a significant quantity of start gas for purge, startup, and slow roll operating conditions, but they are widely used due to their relatively low cost and black-start capability. This effort examines the potential for available, easily adaptable, and new starter concepts and ranked them for various applications.

Abstract:
Increasing legislation and public awareness of noise are intensifying the efforts of industries today to reduce the noise. The natural gas industry has proved that it is one of the industrial leaders in its awareness of noise problems and has maintained a vigorous research program in noise control for over 30 years. A noise survey can be done in several ways: point measurements, grid point methods, contour methods, scanning techniques, etc. The selection of the method depends on the accuracy required, available personnel, expertise etc. For the most accurate determination of sound power, the s
