An advantage steam generator and a steam generation system with an arrangement of heat-exchangers within a hot gas path. To protect the facilities and to increase the efficiency at least at the output of several heat-exchangers an attemperator is arranged, wherein each of them is connected via a fluid distribution valve with a distribution piping.

A learning device, for constructing a learning model for generating a prior acceleration command value for controlling a control target in advance of the time a load on a boiler used for thermal power generation changes, includes: a learner configured to generate the learning model by mechanically learning, as learning data, a data set including a power generation command value for the thermal power generation and the prior acceleration command value which have been used in a previous operation of the boiler.

A boiler facility includes a boiler having a combustion chamber in which a burner is installed, a fuel pipe for supplying fuel to the burner, an air duct for supplying air sucked by a blower to the boiler, an oxygen supplier having an oxygen pipe connected to the air duct and a flow rate controller provided in the oxygen pipe, and a control unit. The control unit sets an air amount that is smaller than the reference air amount for burning the fuel, and controls the blower so that the set air amount is supplied to the boiler. Further, the control unit sets an oxygen amount for fuel combustion, and controls the flow rate controller so that the set oxygen amount is supplied to the air duct.
