An Inverse Dynamic Neuro-Controller (IDNC) is developed to improve the superheater steam temperature control of a 300MW boiler unit. A recurrent neural network was used for building the Inverse Dynamic Process Models (IDPMs) for the superheater system. Two inverse dynamic neural network (NN) models referring to the first-stage and the second-stage water-spray attemperators are constructed

Modelling, identification and control of a grate boiler

Grate boilers are widely used as active steam generation units in Finnish pulp and paper mills to control the steam network of the plant. The fuels burned on grates are typically bark and waste-wood. To ensure good stability and load following properties for grate boilers both drying and combustion processes must be well controlled. This presumes good instrumentation for the grate, special

Model Predictive Fuzzy Control of a Steam Boiler

Abstract. Boilers generate steam continuously and on a large scale. Controlling the boiler process is extremely difficult - it is a highly nonlinear process, its dynamics vary with load and it is strongly multivariable. It is also inherently unstable due to the integrator effect of the drum.
