COGENERATION SYSTEM, COGENERATION SYSTEM CONTROL DEVICE, AND COGENERATION SYSTEM CONTROL METHOD

摘要

An energy saving effect of a cogeneration system is enhanced. A cogeneration system includes a cogeneration device, a fuel gas boiler (through-flow boiler 111), a steam header 114, and a heat source device 101 to which steam is supplied from the steam header 114. The control device of the cogeneration system is a hot / cold water flowing into the heat source unit 101 according to the pressure of the steam header 114, the flow rate of the fuel gas supplied to the once-through boiler 111, and the opening degree of the steam valve 114b of the steam header 114. The control part which increases / decreases the flow volume of is provided. [Selection] Figure 2
