Title:
STEAM SYSTEM AND METHOD OF CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2010/067646
Kind Code:
A1
Abstract:
A steam system provided with a first high-pressure header, a first low-pressure header, a first boiler, and a first turbine. A first supply valve (33A) controls to a preset level the flow rate of steam supplied to the outside from the first low-pressure header. The steam system is also provided with a second low-pressure header. In order that the pressure in the second-low pressure header reaches a preset level, an auxiliary boiler controller controls the amount of supply of steam supplied to the second low-pressure header by an auxiliary boiler. An export line provided with a check valve and a pressure control valve connects the first low-pressure header and the second low-pressure header to each other. An import line provided with a check valve and a flow rate control valve connects the first low-pressure header and the second low-pressure header to each other. The steam system requires a reduced number of boilers.
