Two ongoing projects to improve the existing Cutlass auto boiler control algorithms to provide improved control accuracy, reduced emissions, reduced risk of plant damage, greater operating flexibility and load changing capability.

• Cottam PS (coal fired, 4x500MW) ~ significant improvements to FD combustion air control and superheater steam temperature control. The latter is targeted as reducing plant damage due to temperature exceedances. All areas of the auto-boiler controls will be addressed under this project (firing, drum level control etc).

• Ratcliffe PS (coal fired, 4x500MW) ~ significant improvements to ID/FD draught control giving improving load changing, reduced emissions, and greater operating flexibility. FGD Bypass Control has been improved leading to major reductions in works power with full pay back measured in just days.
