Nowadays, with the rapid progress and development of Chinese society, people’s material level has been continuously improved, demand for electricity also increasing year by year. For thermal power plants, it is great importance to strictly control feedwater quality conduct real-time tracking supervision, as well ensure safety production process. In this paper, we take boiler in process research...

This article presents the results of a techno-economic analysis repowering coal-fired power plant’s steam turbine system to instead accept heat produced by pressurized water reactor-type small modular nuclear (PWR SMR). type challenge due significantly lower pressure and temperature system. A 460 MW supercritical unit with parameters 28 MPa/560 °C/580 °C, operated in Łagisza Power Plant Poland,...

This work focuses on the design and implementation of a nonlinear model-based control system on an experimental reverse-osmosis (RO) membrane water desalination system to address large set-point changes and variations in feedwater salinity. A dynamic nonlinear lumped-parameter model is derived using firstprinciples, and its parameters are computed from experimental data to minimize the error be...

The present paper represents a methodology for investigating flow characteristics near orifice plate by using a commercial computational fluid dynamics code. The flow characteristics near orifice plate which is located in the auxiliary feedwater system were modeled via three different levels of grid and four different types of Reynolds Averaged Navier-Stokes (RANS) equations with proper near-wa...
