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 ...
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 ...
which represents an electrical efficiency of 43.5% in the internal combustion engine. This result is approximate to the one obtained by Rahimpour et al. [20,21,22], in which, with a gas turbine, 2130 MW was produced from 365.5 MMSCFD. In the same conditions this value equaled 5.53 MW pr...
Hot exhaust gases coming from the gas turbine are evacuated to the atmosphere through a stack. The gases pass through a silencer to attenuate the sound of the exhaust gases before being released. In the exhaust system an expansion joint is provided to compensate for thermal expansion in the exh...
Hi all, I need to estimate the mechanical work I can recover from expanding hot air through a gas turbine. So far I am using the equation below, where...
Increasing the electrolyzer efficiency will reduce some of the power needs, as would operating the gas turbine on a blend of hydrogen and natural gas. Thus, large sources of power and water will be required to create a hydr...
The derivation details the factors that are part of the formula, including the discharge coefficient (C4), heat of combustion (Hc), combustion efficiency factor (μ), threshold heat flux (lth), flow factor gas constant (Q), gas temperature (T), emissivity factor (Xg), gas molecular weight...
