Abstract
A fluid system for example for steam raising comprising a flow control device (20), means (28) to supply a head of fluid to the flow control device (20), and at least one fluid using means such as a flash boiler (12-14), the flow control device (20) comprising a chamber (48), an inlet (49) to the chamber from the fluid supply means (28), and an outlet (21-23) from the chamber (48), a valve means (40) associated with the outlet (21-23) operable to direct fluid from the outlet (21-23) either to the fluid using means (12-14) or to a relief means (43-45).
Claims12
A fluid system comprising a plurality of water using boilers, a single pump means, and a flow control device, the flow control device comprising a chamber, an inlet to the chamber, means connecting the inlet to the single pump means which supplies a head of water to the flow control device, and the flow control device further comprising a plurality of outlets, one for each of the water using boilers, a valve means associated with each outlet, means connecting each of the outlets to the respective valve means, each valve means being operable to direct water fed thereto from the associated outlet alternatively to one of the respective water using boilers and a relief means.
A method of operating a fluid system comprising a plurality of water using boilers, a single pump means, and a flow control device, the flow control device comprising a chamber, an inlet to the chamber, means connecting the inlet to the single pump means which supplies a head of water to the flow control device, and the flow control device further comprising a plurality of outlets, one for each of the water using boilers, a valve means associated with each outlet, means connecting each of the outlets to the respective valve means, each valve means being operable to direct water fed thereto from the associated outlet alternatively to one of the respective water using boilers and a relief means, the method comprising the step of sensing a parameter of the system to which each of the boilers contribute, signaling a control means when an upper threshold value of the parameter is sensed, the control means in response deactivating at least one of the boilers and signaling the associated valve means to direct fluid from the respective outlet of the flow control device to the relief means, the sensor means signaling the control means when a lower threshold value of the parameter is sensed, the control means in response reactivating at least one of the boilers which are inactive, and signaling the respective valve means to direct water to the reactivated boiler.
