This paper deals with improvement of superheated steam temperature fuzzy control of high-pressure part in once-through boiler. The improvement of fuzzy control quality is based on optimization of fuzzy controller parameters. The optimization is based on minimization criteria. Optimized fuzzy parameters are function of high pressure steam temperature. More possibilities of optimization are prese...

This paper deals with the state and unmeasured disturbance estimation within the nonlinear model predictive control of the superheated steam temperature in a once-trough boiler of a fossil fuelled power plant. The nonlinear model of the once-trough boiler has very high order, it is significantly nonlinear and load dependent. Model is excited by several disturbances, but not all of them are meas...

The low cost of electricity in some areas facilitates the adoption high-temperature electrolysis plants for large-scale storage electricity. Supercritical water gasification (SCWG) is a promising method syngas production from wet biomass. Additionally, it potential source steam electrochemical plants. However, commercialisation standalone SCWG systems hindered by efficiency and high operating c...

Summary High-temperature electrolysis for reducing H2O (and CO2) to H2 CO) converts concentrated solar energy into fuels and chemical feedstock. We invented an integrated reactor concept comprising a cavity receiver reactant heating, solid oxide electrolyzer (SOE) stack water electrolysis, photovoltaic (PV) cells the SOE stack's electricity demand. A nu...

The cooling of the steel strip in ROT (run out table) of the hot rolling process is very important in that the ROT is the final process to control the mechanical properties of the final products. In general the products are cooled by the circular water jets which makes the comparatively thick residual water layer about 100–200 mm with the supplied flow rate on the plate. The basic phenomenon go...

Coupled electro-thermal field exists widely in chemical batteries and electrolysis industry. In this study, a three-dimensional numerical model, which is based on the finite-element software ANSYS, has been built to simulate the electro-thermal field in a magnesium electrolysis cell. The adjustment of the relative position of the anode and cathode can change the energy consumption of the magnes...
