Abstract: A system for producing steam includes a source of superheated water with superheated water output; a membrane filtration system in fluid communication with the superheated water output and including a membrane filter with a permeate side and an opposing retentate side. The membrane filter includes a separation membrane constructed to reject organic molecules. The system may be used for removing organic compounds, such as anti-corrosion agents or contaminants, from superheated water to produce steam. A method for producing steam includes directing a cross-flow of heated pressurized water including a first concentration of an organic compound across a membrane filter. The membrane filter includes a separation membrane constructed to reject the organic compound; and one or more support layers adjacent the separation membrane. A steam permeate including a second concentration of the organic compound is collected, where the second concentration is lower than the first.

Abstract: A system can quickly cool and de-pressurize a boiler arrangement under non-normal operating conditions such as loss of plant power. A discharge system injects into the furnace a combined stream of steam from a steam discharge system and ambient air, thereby both cooling components of the boiler arrangement and reducing pressure in the steam/water circuit. This reduces or eliminates the additional cost associated with providing extra capacity in a steam drum and/or an independently powered boiler water pump. The system is particularly useful for quickly cooling the U-beams of a circulating fluidized bed boiler during a black plant condition.

Abstract: Disclosed is a method of controlling a real-time oxidation-reduction potential in a hot water system to inhibit corrosion in the hot water system. The method includes defining one or more operational protective zones in the hot water system. One or more of the operational protective zones includes an oxidation-reduction potential probe that is operable to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the measured real-time potential to the controller, which assesses and interprets the transmitted potential to determine whether it conforms to an oxidation-reduction potential setting. If the measured potential does not conform the oxidation-reduction potential setting, the controller is operable to feed or remove one or more active chemical species into or from the hot water system and further operable to change at least one system parameter.

Abstract: A method for generating steam from a feedwater inlet stream including impurities is disclosed. The method involves receiving the feedwater inlet stream at an inlet of a steam generator and causing the feedwater stream to flow through a tubing circuit to an outlet of the tubing circuit, the tubing circuit having a substantially un-rifled bore defined by a metal wall. The method also involves delivering a heat flux to the feedwater stream through the metal wall of the tubing circuit to generate steam by causing evaporation of feedwater within the tubing circuit, and controlling at least one of a flow rate of the feedwater stream and the heat flux to cause generation of an outlet stream at the outlet includes a steam portion and liquid phase portion, the steam portion being greater than about 80% of the outlet stream by mass. The steam portion provides sufficient cooling of the metal wall to maintain a wall temperature at less than a threshold temperature.

Abstract: Methods and systems relate to generating steam from water that may be recycled in thermal oil recovery processes and is heated in tubes having non-obtrusive features to limit fouling formation. The tubes may include jets to generate enhanced flow mixing along an inner wall of the tubes in order to increase heat transfer and disrupt bubble nucleation. Employing the tubes with the inner wall having an average surface roughness of less than one micron may further facilitate disruption of the bubble nucleation.

Abstract: At least one injector condenser (20) is used to supply secondary feedwater to the steam generator (1) during a phase in the course of which the temperature and the pressure of the coolant of the reactor coolant system (2) of the nuclear reactor are varied between hot shutdown conditions of the nuclear reactor and conditions making it possible to bring into service the residual heat cooling system (RRA). The injector condenser (20) is fed with steam withdrawn from an upper part of the steam generator (1), at a first inlet, and with feedwater from a storage tank (10), at a second inlet. High-temperature pressurized feedwater is supplied to the steam generator (1) by means of one injector condenser (20) outlet. The steam generator (1) is fed without using an additional pump for withdrawing feedwater from the storage tank (10) and for injecting feedwater into the secondary part (3) of the steam generator (1).

Abstract: In a steam generator or boiler used in a nuclear reactor, the secondary water is supplied via at least one pipe (48) issuing directly into the bottom of an annular recirculation space (32) formed between the outer envelope (10) and an inner envelope (26) surrounding inverted U-tubes (24), on the side of the cold branches of the tubes. A perforated collar or flange (56) placed in the annular space (32), above the pipe (48), produces a pressure drop or flow limitation preventing the rise of the feed water and controls the circumferential distribution of the recirculation water, which drops from the separators (28).
