Model Based Control of the Circulating Fluidized Bed …

1/1/2009 · The CFB boiler dynamics is represented by a non-linear low order model which captures the key CFB boiler behavior. The model exhibits strong cross-interactions between the process variables, therefore the control based on single input single output PID loops is difficult; however, it is shown the CFB boiler can be successfully controlled using the multiple-inputs multiple-outputs (MIMO) model.

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.

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
