BOILER SYSTEM, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/039311
Kind Code:
A1
Abstract:
The present invention efficiently lowers the surface temperature of pipes that make up a boiler system, thereby suppressing high-temperature corrosion of the pipes. A boiler system 1 comprises: a pipe (first connection pipe 14, second connection pipe 15, reheater pipe 40a) for circulating steam; and a steam temperature control unit (pump 7, pipes 7a, 7b, 7c, first regulating valve 18, second regulating valve 19, third regulating valve 60, control unit 30) that lowers the temperature (T1, T3, T5) of the steam circulating through the pipe below a predetermined temperature (T12, T34, T56) by supplying fluid to the interior of the pipe.
