Present situation and development of superheated steam temperature control in steam drum boiler of thermal power plant

The superheated steam temperature is the maximum temperature in steam drum boiler of thermal power plant, it has the significant influence regarding the power plant security economy movement.Because the steam warm adjustment process is a typical big extends, big inertial system, it hardly be controlled well for the multi-capacities. The perturbation factor is multitudinous, enable the steam warm adjustment to have the very major difficulty. In this paper, the structure, control methods and present situation and development of the superheaded steam temperature in steam drum boiler of thermal power station are introduced.
