Title:

BOILER SYSTEM, POWER GENERATION PLANT, AND BOILER SYSTEM OPERATION METHOD

Document Type and Number:

WIPO Patent Application WO/2020/110473

Kind Code:

A1

Abstract:

The purpose of the invention is to have the temperature of vapor generated by a boiler be a desired temperature even when variations in solar radiation occur. A boiler system (1) comprises: a boiler (3) that generates vapor from feed water; a fourth feed water pipe (23) through which feed water supplied to the boiler (3) passes; a solar heat collector (51) that heats a heat transfer medium by using the heat generated by collecting solar heat; a circulation channel (50) that circulates the heat transfer medium; a solar feed water heater (52) that performs heat exchange between the feed water flowing through the fourth feed water pipe (23) and the heat transfer medium flowing through the circulation channel (50); and a spray water volume regulating valve (39a) and a fuel flow rate regulating valve (33a) that are provided in the boiler (3) and that regulate the temperature of the vapor generated by the boiler (3).
