In this chapter we have seen how a `master demand' signal is generated with respect to the nature of the duties that the plant is designed to undertake. This signal is responsible for ensuring that the boiler reacts to changes in demand, and it must also coordinate the operation of each of the subsidiary systems. The main areas involved in this process are the combustion and draught systems in conventional boilers, the feedwater and the steam temperature control systems in both conventional boilers and HRSGs.
