Gas Turbine Combustion Efficiency Calculations: A Study of Fundamental Concepts and the Derivation of a Practical FormulaTHE alternative definitions of combustion efficiency based on the ratio of actual to theoretical heat releases and of theoretical to actual fuel requirements are discussed in relation ...
The semi-empirical data that was used in their model was in the form of non-dimensional compressor and turbine maps. These maps provided steady state mass flow, pressure ratio and efficiency as a function of the rotational speed of the shaft. The first map plotted the pressure ratio versus ...
For gas turbine engines operating at constant rpm, power output is controlled by fuel flow into the engine. The performance of gas turbine engines is affected by compressor efficiency, turbine efficiency, pressure ratio, peak cycle temperature, and combustion efficiency. Compressor and turbine ...
formula obtained for this type gas turbine are consistent with the practical data.The part-load performance of cogeneration is studied with saturated steam supply.It is pointed out that the approaching temperature difference may be negative in low load condition with high steam parameter and low ...

Currently, there are not enough studies related to the co-pyrolysis of mixed biomass. The main objective was to identify the conditions when the efficiency of pyrolysis of mixed biomass in a gas medium with a variable component composition and temperature can be significantly improved. The paper ...
stage turbine. In fact, a single stage turbine can work up to a pressure ratio of 4 with an acceptable efficiency. Let us search for the compressor pressure ratio which yields exactly the turbine pressure ratio of 4. Close this window to proceed. ...
Gas turbine maintenance and inspection model enhancement Hydrocarbon Processing / February 2025 Improving asset performance is a major concern throughout industry and is associated with maintenance costs, experience, machine/equipment age, and operational and environmental conditions. This article will focus ...
This gas turbine produces up to 58 MW (77,852 ISO horsepower), has a net efficiency of 41.3%, and can drive a load on either or both ends. Sign in to download full-size image Fig. 8.1.3. LM 6000 aeroderivative gas turbines.(Courtesy of General Electric.) The advantages and ...
In such cases, due to the lack of information and difficulties in prediction of gas turbine and compressor efficiency, techniques which depend on experimental data such as artificial neural networks (ANNs) may be applied. In their work they use ANNs within a genetic algorithm to predict the ...
