MODELLING APPROACH TO SUPERHEATER OF A BOILER

Modeling and simulation of a natural circulation water …15/10/2019 · Backi [] introduces a nonlinear approach to determine the medium enthalpy dynamics between the inlet of heater water (economizer) and the outlet of once-through boiler evaporator. Dhanuskodi et al. [ 8 ] developed a supercritical steam boiler model to predict the temperature of the tube inner wall using artificial neural networks.(PDF) Generalized minimum variance control of steam …This paper develops a nonlinear neuro-fuzzy network modelling and predictive control method and then apply it to the superheater steam temperature control system on 200MW unit steam-boiler. AMN(Associate Memory Network) is used as process predictive model because it provides a direct link between artificial neural networks and the fuzzy systems.

A NETWORK APPROACH APPLIED IN MODELLING THE HEAT …A 1-D thermo-fluid model for a superheater in coal-fired boilers was developed using the network approach encapsulated in the commercial software Flownex. This model brings to light the relationship between the boiler operations, the thermo-fluidCFD study of pulverized coal-fired boiler evaporator and …The modelling approach was applied to the boiler of a 620 MWe power plant. The results for 99%, 81% and 60% boiler loads compare well with experimental data. The proposed methodology forms the bases for a co-simulation framework which combines the CFD with a systems-level process modelling tool that can capture the internal steam maldistribution at low loads and the resultant effect on the metal …
