20120247406 | METHOD OF CONTROLLING DRUM TEMPERATURE TRANSIENTS - An evaporator system comprises an evaporator; a drum; and a pump that are in fluid communication with each other. The pump is operative to create a temporary pressure gradient during start-up of an evaporator system and transport a fluid from the evaporator to the drum prior to the fluid reaching its boiling point in the evaporator. Following the fluid reaching its boiling point in the evaporator, the fluid naturally circulates in the evaporator system. | 10-04-2012 |
20120325940 | NOZZLE AND NOZZLE ASSEMBLY CONFIGURED TO MINIMIZE COMBINED THERMAL AND PRESSURE STRESS DURING TRANSIENTS - In a nozzle and a nozzle assembly, for use in a pressure vessel, stress analysis is used to determine areas of stress concentration. The nozzle is configured to reduce these stress concentrations. | 12-27-2012 |
20140238019 | SYSTEM AND METHOD FOR PRE-STARTUP AND POST-SHUTDOWN PREPARATIONS OF STEAM GENERATORS OR POWER PLANTS - System and method for pre-startup or post-shutdown preparation for such power plants are disclosed which are subject to frequent startups and shutdowns, such as a solar operated power plant. The system and method introduces an auxiliary fluid flow to be circulated in an opposite direction to a direction of normal working fluid flow responsible for producing electricity. That is, if the working fluid flow in a first direction for operating the power plant, than the auxiliary fluid flows in a second direction, opposite to the first direction. The auxiliary fluid flows in the second direction for a predetermined time and at a predetermined conditions through a plurality of superheater panel arrangements of solar receiver former to activation of the working fluid circuit, as pre-startup preparation of the power plant, and after cessation of the working fluid circuit, as post-shutdown preparation of the power plant, to attain predetermined conditions in the superheater. | 08-28-2014 |

20150128593 | AUXILIARY STEAM SUPPLY SYSTEM IN SOLAR POWER PLANTS - An auxiliary steam supply system in a solar power plant includes a solar receiver having a superheater section, a turbine, a steam circuit, a thermal energy storage arrangement and an auxiliary steam circuit. The thermal energy storage arrangement, including a thermal energy storage medium, is configured for the steam circuit to receive a portion of the steam to heat the thermal energy storage medium. The thermal energy storage arrangement may receive the steam from any location across the superheater section. Moreover, the auxiliary steam circuit generating auxiliary steam flow, which thermally communicates with the thermal energy storage arrangement to be heated, is introduced to any location across the superheater section. Capacity of the thermal energy storage arrangement may be relatively small as compared to the solar receiver and may be compact for placement on top of a tower. | 05-14-2015 |

20150362218 | SOLAR RECEIVER CONFIGURATION - A solar receiver configuration (receiver) adapted to include a plurality of receiver heat transfer passes. Each pass includes a plurality of panels. Further, each panel includes a plurality of tubes, tangentially arranged, vertically extending between horizontally placed lower and upper headers. The headers, which are pipe assemblies with closed ends, of adjacent panels are horizontally and vertically offset one to another to form a substantially continuous tube surface. Such continuous tube surface enables solar heating of the fluid flow therefrom in at least a parallel flow arrangement and a serpentine flow arrangement. | 12-17-2015 |
