Title:
BOILER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/109072
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a boiler system which is capable of improving pressure stability without repeatedly starting and stopping boilers. A boiler system (1) is provided with: a boiler group (2) provided with a plurality of boilers (20) capable of burning fuel while the load factor is being continuously changed; and a controller (4) for controlling a fuel-burning state of the boiler group (2) in accordance with a required load. In cases when a required steam amount required in accordance with the required load exceeds an increase-reference steam amount, the controller (4) increases the number of the boilers (20) made to burn fuel. At this time, the increase-reference steam amount is set by adding an increase hysteresis to a stop-reference steam amount serving as a reference for causing one of the boilers (20) from among the boilers (20) in a fuel-burning state to stop burning fuel, thereby inhibiting stoppage of the boilers (20) immediately after increasing the number of the boilers (20).
