Most of the electric power produced worldwide is based on fossil fuel combustion, largely in plants operating with low efficiency cycles. The large amounts of fuel consumed in this process release harmful emissions including toxic nitrogen and sulfur oxides, mercury, and greenhouse gases such as carbon dioxide. The necessity to reduce the negative impact of power generation on the environment, ...

The aeroderivate gas turbines are widely used for power generation in the oil and gas industry. In offshore marine platforms, the aeroderivative gas turbines provide the energy required to drive mechanically compressors, pumps and electric generators. Therefore, the study of the performance of aeroderivate gas turbines based on a parametric analysis is relevant to carry out a diagnostic of the ...

Cooling characteristics are given in terms of the variation of average blade temperature at mid-span with cooling-flow rate, Reynolds number, gas/cooling-air absolute temperature ratio, and, for the rotor, gas-stream incidence. Chordwise and spanwise variations of blade temperature are also presented. Measured pressure-drop characteristics indicate that in a gas-turbine engine, with the cooling...

A design point simulation and adaptation of anindustrial GE LM2500+ gas turbine engine is presented. The design point is chosen when the engine runs steadily at operating point and close to the nominal design condition at 29MW power output. The targeted performance parameters are the fuel flow rate (FF), the compressor exit total pressure (P3), the compressor turbine total exit temperature (T8)...

The current research is aimed at carrying out an exergy analysis of a 33-MW gas turbine power plant that operates on the Brayton cycle. Quantitative exergy analysis for each component and for the whole system was done. Based on the exergy balance models developed, a computer program is written which is used to investigate the performance of the power plant under varying ambient and turbine inle...

A reliability model for a power generating system comprising two gas turbines and one steam turbine is developed wherein scheduled inspection is done at regular interval of time for maintenance. Initially, all the three units i.e. two gas turbines as well as one the steam turbine are operating and working of the system is called the working at full capacity. On failure of one of the gas turbine...

The present chapter addresses the problems of gas turbine gas path diagnostics solved using artificial neural networks. As a very complex and expensive mechanical system, a gas turbine should be effectively monitored and diagnosed. Being universal and powerful approximation and classification techniques, neural networks have become widespread in gas turbine health monitoring over the past few y...

This paper describes a construction and characteristics of a coal-gas-burning high e ciency power plant which emits no carbon dioxide (CO 2 ) into the atmosphere. In the plant, CO 2 gas and superheated steam are used as the main and sub working uid, respectively, of a closed dual uid gas turbine power generation system. It is assumed that a coal gas whose principal compositions are CO, H 2 , CO...
