Availability analysis of heat recovery steam generators used in thermal power plants
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The combined-cycle gas and steam turbine power plant presents three main pieces of equipment: gas turbines, steam turbines and heat recovery steam generator (HRSG). In case of HRSG failure the steam cycle is shut down, ...
Minimization of life cycle CO2 emissions in steam and power plants
(Springer, 2009-08)
A methodology is presented to minimize life cycle CO2 emissions through the selection of the operating conditions of a steam and power generation plant. The battery limits of the utility plant are extended to include CO2 ...
Air and Steam Gasification of Almond Biomass
(Frontiers Media Sa, 2019-08-21)
Experiments were performed on a laboratory scale fluidized bed gasifier to characterize the gasification products of almond shell and hull removed in nut processing operations and to determine the effect of gasifying media ...
Hydrogen generation from renewables: Steam reforming of ethanol and dimethyl ether over structured catalysts
(Teknoscienze Publisher, 2009-09)
Ethanol and dimethyl ether can be efficiently reformed with steam over appropriate catalysts for generating hydrogen. Both substrates provide a valuable example of the use of renewable chemicals for energy applications. ...
Catalytic walls and micro-devices for generating hydrogen by low temperature steam reforming of ethanol
(Elsevier Science, 2009-05-21)
Ethanol steam reforming (S/C = 3) was effectively performed at low temperature over catalytic wall reactors comprising a wide range of channel dimensions, ranging from conventional monoliths (channel width of 0.9 mm) to ...
Thermodynamic analysis of direct steam reforming of ethanol in molten carbonate fuel cell
(Asme-amer Soc Mechanical Eng, 2008-05-01)
Fuel cell as molten carbonate fuel cell (MCFC) operates at high temperatures. Thus, cogeneration processes may be performed, generating heat for its own process or for other purposes of steam generation in the industry. ...
Erosion-fatigue of steam turbine blades
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The premature failure of steam turbine rotor blades, manufactured in forged 12% Cr-NiMoV martensitic stainless steel, was investigated using visual inspection non-destructive testing, macro and microfractography, microstructural ...
Bio-ethanol steam reforming and autothermal reforming in 3-μm channels coated with RhPd/CeO2 for hydrogen generation
(Elsevier Science, 2013-02)
A silicon micromonolith of 7 mm diameter and 0.2 mm length containing 1.5 million regular channels with a diameter of 3.3 μm was used for obtaining hydrogen through ethanol or bio-ethanol steam reforming (ESR) and oxidative ...
Exergoenvironmental analysis of hydrogen production through glycerol steam reforming
(2021-01-01)
The increase in biodiesel production is leading to a scenario in which more glycerol, which is a by-product of this biofuel production, is generated each day. Among the many potential applications for this substance, steam ...
Failure Assessment Diagram in Structural Integrity Analysis of Steam Generator Tubes
(Elsevier Science, 2015-07-02)
The assessment of the structural integrity of Steam Generator Tubes (SGTs) in nuclear power plants has been receiving increasing attention in the literature in the last years due to the negative impact related to their ...
