MULTI-BOILER INSTALLATION SYSTEM OF BOILERS WITH NUMBER- OF-BOILERS CONTROLLER

摘要

PROBLEM TO BE SOLVED: To prevent deteriorating of stability of vapor pressure and to prevent an oscillation in a multi-boiler installation system of boilers. ;SOLUTION: In the multi-boiler installation system of boilers with a number- of-boilers controller 3 for controlling number of the boilers by installing a plurality of boilers 1, gathering vapors generated at the respective boilers, then supplying the vapors to a vapor using equipment 2, dividing the control pressure width of the vapor pressure, setting a plurality of pressure control sections, deciding the number of burning boilers according to the pressure value of the gathered vapors, and burning the boilers of necessary number, if the boiler 1 which cannot operate is brought about of the boilers controlled in the number, the boiler which cannot operate is separated from the control of the number, the pressure control sections are reset, and the number is controlled based on the reset pressure control sections.;COPYRIGHT: (C)2001,JPO
