<P>PROBLEM TO BE SOLVED: To prevent increase of facility costs and running costs, to suppress fluctuation of a main steam pressure, and to suppress change of a power generation amount of a turbine generator, in supplying process steam from a boiler turbine power generating facilities to factory facilities. <P>SOLUTION: In this steam supply system 5 having a steam supplying system 3 for supplying the process steam from the boiler turbine power generating facilities 1 to the factory facilities 2, and a control device 4, or a method of controlling the same and a method of supplying steam, the steam supplying system 3 includes a bleed pipe 40 for branching and extracting part of the steam generated from a boiler 10, an accumulator 42 for storing the steam extracted from the bleed pipe 40 and reduced in its temperature and pressure, and a factory steam pipe 43 for supplying the stored steam to the factory facilities 2 as the process steam, and the control device 4 implements control for replenishment by calculating a necessary fuel charging amount to the boiler 10 on the basis of the pressure, temperature and flow rate of the process steam flowing in the factory steam pipe 43, and adding the same to fuel charging command. <P>COPYRIGHT: (C)2012,JPO&INPIT |
