Document Type and Number:
WIPO Patent Application WO/2010/038506
Kind Code:
A1
Abstract:
Disclosed is a control program for controlling combustion of a boiler group consisting of a plurality of boilers in which the quantity of evaporation can be controlled at stepwise combustion positions. Also provided is a control system and a boiler system. In a control program performing control of a boiler system comprising a boiler group consisting of a plurality of boilers in which the quantity of evaporation can be controlled at stepwise combustion positions and arranged to perform combustion control based on a demanded load, when combustion of any boiler among the boiler group is started, backup control for temporarily raising the combustion position of any one of those boilers which are already under combustion is possible, and when the quantity of evaporation increased by raising the combustion position of a boiler capable of backup control goes above the shortage quantity of evaporation, the timing for starting backup control is controlled depending on the rate of change of at least one physical quantity corresponding to the quantity of evaporation.
