Weber When steam power cycles are modeled, thermodynamic properties as functions of pressure and temperature are required in the critical and supercritical regions (region 3 of IAPWS...

...Atsushi Katoh; Masahisa Shinoda; Kuniyuki Kitagawa; Ashwani K. Gupta Addition of steam to a flame has important implications in the combustion process. The dissociation of the added steam (e.g., H 2 O ↔ H + OH , etc.) is one of the effects that contribute to the production of radical species...

... belonging to the same typology are proposed. These cycles use water/steam as working fluid, which is compressed in liquid and vapor phase, and the internal combustion process, which takes place between syngas and pure oxygen. The top Brayton cycle and the bottom Rankine cycle are integrated together...

.... 8 Deviation from the basic equation in T sat with IST-85 tolerances The computing speeds of TTSE functions were compared with IF97. The FORTRAN codes in “ASME Steam Properties for Industrial Use Based on IAPWS-IF97, Professional Version” ( 11 ) were used as the reference...

...A. F. Massardo, Mem. ASME; B. Bosio The aim of this work is to investigate the performance of molten carbonate fuel cells (MCFCs), with external sensible heat reformer and gas turbine/steam turbine (GT/ST) combined cycles. The analysis of these MCFC-GT/ST combined cycles has been carried out using...

... percent total fuel), and equivalence ratio (0.4 to 0.8 depending on the moisture levels). The moisture levels were achieved by injecting steam into dry air well upstream of the fuel-air premixing nozzle. Computations were made for comparison to the experiments using GRI Mech 2.11 kinetics...

... at an additional cost of about 13 mill$/kWh. The plant configuration based on steam/methane reforming presents poorer performance (2.5 percentage point lower efficiency and 22 percent loss of power output, based on the same gas turbine unit). The atmospheric operations anticipate higher dimensions and costs...

...T. Nakagaki; T. Ogawa; K. Murata; Y. Nakata The purpose of the present work is to establish the design method of methanol steam-reformer for application to chemical recuperation in a gas turbine system. The reaction rate of the methanol steam-reforming was measured with a small amount of catalyst...

...N. Beithou, Graduate Student; H. S. Aybar, Assoc. Mem. ASME, Associate Professor, There are several proposed advanced reactor systems, which consider the utilization of a steam-driven jet pump (SDJP) as an emergency core cooling system. The steam-driven jet pump is a device without moving parts...
