SYSTEM FOR AUTOMATIC REGULATION OF STEAM PRESSURE IN THE MAIN LINE OF A DRUM BOILER

摘要

FIELD: boiler engineering. ;SUBSTANCE: invention relates to automatic control systems for drum steam boilers and can be used for pressure control tasks, in particular the steam pressure in the main line of a drum steam boiler. The system consists of a drum steam boiler with a furnace unit, a steam line, a pressure sensor, a pressure transmitter, an executive unit (dust preparation system), an adaptive regulator, a reference predictor, a filter-corrector, and the second adder.;EFFECT: invention expands the functionality of the system, i.e. ensures the possibility of controlling objects only the output signal of which is available for measurement (not its derivatives), improves the quality of work in case of a significant change in the parameters of the object and the presence of disturbances with a relatively simple implementation of the control loop. ;1 cl, 5 dwg
