Abstract: | This paper presents an analysis of main problems of controlling small- and medium-size steam boilers. Noted are deficiencies of current normative and technical documents, as well as those of the traditional concept of the process of fuel firing, the methods for and algorithms of boiler control. There is established an approach to creation of such control systems in which a boiler is treated, as to control and load channels, as a nonlinear linked controlled objects. To control load and efficiency of a boiler, an universal schematic diagram is suggested that allows for the possibility of implementation in modern controllers of both known methods and a new method using an extremal governor, which would provide minimum fuel consumption at given thermal load of a boiler. |
