To solve the water wall overheating in lower furnace, and further reduce NOx emissions carbon fly ash, continuous improvement of previously proposed multiple injection staging combustion (MIMSC) technology lies on three aspects: (1) along furnace arch breadth, changing centralized 12 burner groups into a more uniform pattern with 24 burners; (2) increasing mass ratio pulverized coal fuel-rich flow to that fuel-lean from 6:4 9:1; (3) reducing arch-air momentum by 23% tertiary-air 24%....
Hydrocyclones have the advantages of fast separation speed, simple structure, small footprint, and convenient operation/maintenance, resulting in satisfactory performance wide applications. However, conventional hydrocyclones are incapable separating fine particles or droplets. A hydrocyclone with media-size redistribution (HMSR) was designed studied to alleviate this shortcoming. The overall efficiency could be improved by design. Based on theory analysis numerical simulation, mechanism...
We reexamine the method of upward integration a nonlinear force-free field (NFFF), which is, as is well known, an ill-posed problem. It can be modified to well-posed one by following means: instead using finite difference express partial derivatives, we use smooth continuous functions approach magnetic values, write down three components consisting amplitude multiplying morphology functions, and reduce four basic NFFF equations ordinary differential ones. They are then solved in asymptotic...
The economic and efficient treatment of mixed media in offshore produced fluids is great significance to oilfield production. Due the small space limited load-bearing capacity platforms, some mature multiphase separation processes onshore oilfields are difficult apply. Therefore, high-efficiency processing methods with small-occupied required. Mini hydrocyclones (MHCs) a potential method due their simple structure, footprint, high efficiency (especially for fine particles or droplets)....
Aims.The aim of this paper is to understand the magnetic configuration and evolution an active region, which permitted X1.7 flare be observed during decaying phase a long-duration X1.5 on 2005 September 13.
Hydrocyclones are widely used in the separation of two-phase immiscible mixtures. In various application scenarios, three-phase hydrocyclones (3PH) often urgently needed. this work, typical 3PHs classified into six categories according to their structural characteristics. A comprehensive analysis feature, design points and processing difficulties carried out provide guidance for 3PH structure. On basis, technical economic analyses conducted based on operating parameters, performance pressure...
Numerical simulations and industrial experiments were conducted to study the effect of stoichiometric ratio fuel-rich flow (0.46, 0.49, 0.51, 0.53, 0.55) on flow, combustion, NOx emission characteristics in a 600-megawatt electric (MWe) supercritical down-fired boiler with multiple-injection multiple-staging combustion technology. The simulation results indicate that as increases from 0.46 0.55, fields all form symmetric W-shaped pattern; this is identical temperature distributions obtained...
Under the approximation of incompressible flow, we solve both momentum equations (for neutrals and ions) magnetic induction equation at three-dimensional level, obtaining solutions for steady spine fan reconnection in partially ionized plasmas. In case weak coupling between two species, sharp structures can form not only field but also ions' velocity, while level "sharpness" falls off by an order ionization degree. strong when species move together appear field. The results could be used to...
