Once-through steam generator in concentric annuli tube is a new type steam generator which adopts structure of double-face heat transfer. The model of steam generator is built by lumped parameters with moving boundary. In the basis of the built model, static and dynamic characteristics are analyzed. Because thermal capacity is relatively less, it enhances difficulty of control. On the basis of trails...
Because the water cubage is small, heat energy is few in the once through steam generator (OTSG), disturbs possess uncertain and non-linear, and the pressure of outlet steam is controller difficultly during load changes, on-line adjusted coordinated control based on fuzzy neural network of standard model is applied to control the outlet steam pressure of OTSG. The simulation results shows that the...
The internal ring matrix distribution of many special ceramic porous medium tubes on a circular plate constitutes an adsorbent device, which can retain nanoparticles aerosol agglomerate by the way of collision, adsorption and diffusion in the process of mass transfer. In this paper, the behavior of industrial flue dust diffusion in the ceramic porous medium device is researched by computational fluid...
