Title: Boiler control method
Inventor: TASHIRO ICHIRO
IPC: F22B35/00
Filed: 1988-03-10
Abstract: PURPOSE:To prevent fluctuation of main steam pressure and temperature and improve controllability of generator output by adding a BIR signal to a boiler master signal which is obtained by converting a load dispatching instruction into function and converting the added signal into function. CONSTITUTION:Since a BIR signal 15 which is set by a function generator 14 through a differentiator 13 on the basis of a load dispatching instruction and corrected by a load correcting gain 18 is added to a boiler master signal 3 which is a basis of boiler control, a feed water instruction 5, a burning quantity instruction 7 and an air flow instruction 9 generated through function generators 4, 6, 8 are in the conditions that the BIR signals corresponding to load are added. Therefore, since the quantity of the BIR signals 28, 29, 30 added to each instruction 5, 7, 9 can be lessened and its regulating width can be decreased, the control is stabilized, the fluctuation of main steam pressure and temperature are prevented and the controllability of generator output can be improved.

Abstract: PURPOSE:To improve effective permeability, increase magnetic flux, obtain excellent magnetic properties and reduce a core in size, by forming the core to be circular in cross-section. CONSTITUTION:A ferrite core 1, 8 is employed which is no cut surface and can be formed into any desired shape as well as is excellent in magnetic properties. For the application of a cylindrical coil bobbin 12 for providing a winding thereon, the cross- sectional configuration of the core is selected to be a circle 9 or a polygon 10 close to a circle or a circular square 11 which is closer to a circle, so that the cross-sectional configuration is completely matched with the inner peripheral configuration of the coil bobbin 12. Two parts of the cylindrical coil bobbin 12 which is divided beforehand are bonded together. The coil bobbin 12 is rotated with respect to the core when the winding is provided. Forming the core to have the circular cross-section 9 permits the gap between the core and the bobbin 12 to be completely small. In addition, since the ferrite core is employed, it is possible to improve effective permeability and obtain excellent magnetic properties. At the same time, the core can be reduced in size, so that working properties are improved. It is to be noted that as the cross-sectional configuration of the ferrite core, the configuration 9 is most efficient, followed by the configuration 11 and then the configuration 10 in the drawing.
