Once-through steam generator control

CHAPTER 2 Steam Generators - EMU Academic Staff Directory

Forced-convection boiling Besides pool boiling, vapor is also generated by passing liquid through a tube heated either by firing fuel, as in a once-through boiler, or by condensing steam, as is commonly used in process industries. This method of generating vapor is

Once-through boiler steam temperature control using Dynamic Matrix Control …

29/7/2010 · This paper presents an application of Dynamic Matrix Control (DMC) for controlling steam temperatures in a large-scale once-through boiler-turbine system. In order to control the steam temperatures, we choose a spray and a damper as two controllers. The step response model for the DMC is generated for the two major output variables, superheater and reheater temperatures, by performing …
