Show The MSW burning boi ler has a conventional superheater with temperature UP to 300°C, and is desinged so that the steam turbine can continue to operate whi Ie the gas turbine is turned off, such as at night time. Figure 13 below shows the flow system. The differences of this system from the basel ine are I isted below.
