Steam injection for power and efficiency augmentation in aeroderivative gas turbines has been commercially established for natural gas-fired cogeneration since 1980. Steam-injected gas turbines fired with coal and biomass are being developed. A performance and economic assessment of biomass integratedgasifier steam-injected gas turbine (BIGISTIG) cogeneration systems is carried out here. A deta...

The use of controlled heating to separate centrif­ ugally the white and green protein fractions from freshly expressed alfalfa juice has been investi­ gated. Heating in a batch-type operation, with a slug flow heat exchanger, or by direct steam injec­ tion has been conducted over a range of tempera­ tures (30-64°), times (10 sec-20 min), and pH values (5.5-8.6). Results indicate a superiority o...

Injecting hot steam into the cascade flow is one of procedures for resisting losses and damages caused by condensation. In current study, utilizing a 3D (three-dimensional) geometry turbine blades, has been injected via embedded channel. power plant industry, injection process done in two ways: constant pressure with reservoir or mass rate control valve. Therefore, considering these methods TOP...

Solvent–steam mixture is a key factor in controlling the economic efficiency of the solvent-aided thermal injection process for producing bitumen in a highly viscous oil sands reservoir. This paper depicts a strategy to quickly provide trade-off operating conditions of the Expanding Solvent–Steam Assisted Gravity Drainage (ES-SAGD) process based on Pareto-optimality. Response surface models are...

Integrated solar thermal steam generation and heavy-oil recovery projects have garnered interest because of their ability to decrease the variability of steam generation costs arising from fluctuations in natural gas prices as well as life-cycle carbon dioxide emissions. The viability of a solar thermal steam generation system (with and without natural gas back-up) for thermal enhanced oil reco...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

A device using a steam injection funnel is described by means of which air can be driven quickly and surely from an autoclave load. It is simple and inexpensive, necessitates no changes in the working routine of a microbiology laboratory, and does not interfere with the operation of the autoclave in its normal mode.
