Abstract:
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.
Abstract:
An energy exchange system employing a hot water loop, a chilled water loop, an energy exchanger, a boiler plant for heating water flowing through the hot water loop and for heating water flowing through the chilled water loop via the energy exchanger, a chiller plant for chilling the water flowing through the chilled water loop and for chilling the water flowing through the hot water loop via the energy exchanger, and a control for calculating a hot energy load for operating the at least one boiler to heat the water flowing through the hot water loop and for heating the water flowing through the chilled water loop via the energy exchanger, and for calculating a chilled water energy load for operating the at least one chiller to chill the water flowing through the chilled water loop and for chilling the water flowing through the hot water loop via the energy exchanger.
Abstract:
A fluid recirculation system includes an arrangement of a flow control valve located to receive a flow of fluid from an inlet. The system further comprises an economizer inlet mixing device located to receive the flow of hotter fluid from the arrangement of the flow control valve and from a cooler feedwater stream. An economizer inlet mixing device located upstream of an economizer in a supercritical pressure boiler includes a sparger assembly through which a flow of fluid from the waterwall outlet is received, an inlet through which a flow of fluid from a feed stream is received, and a wave breaker assembly through which an outlet stream from the economizer inlet mixing device is directed.
Abstract:
An entertainment system (1019, 2) having a fluid system with a smoke generator (1007, 4), the smoke generator being supplied from at least one pump (1005, 8, 10) connected to at least one container for fluid (1003, 12, 14), which at least one pump (1005, 8, 10) is controlled by a controller (1009, 6), wherein the controller is adapted to perform a shutdown process upon malfunctioning of at least a part of the entertainment system. The shutdown process performs a purge of at least part of the fluid system. Furthermore, a method of operating the entertainment system (1001, 2), has the steps of performing a shutdown process upon malfunctioning of at least a part of the entertainment system, the shutdown process including the step of purging (2009, 3003a, 3003b) at least a part of said fluid system.
