Abstract

A solar tower central receiver with separated boiler and Super-Heater allows better control on the output steam's temperature. The boiler takes higher solar flux density and works at lower temperature while the Super-Heater takes lower solar flux and works at high temperature to optimize the cost to performance ratio. The solar fluxes of the boiler and super-heater are adjustable through the pointing of the heliostats. The boiler consists of parallel pipes as solar absorber and the Super-Heater consists of helix parallel pipes as solar absorber. The steam drum chamber interconnects boiler and Super-Heater. The absorb pipes and circulation pipes are connected to water chamber, steam drum chamber, and Super-Heater chambers. The water level sensor and temperature sensors provide information regarding the operating status of the receiver.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention broadly relates to a central solar energy receiver and more particularly it relates to a solar energy receiver assembly for receiving radiant energy and generating steam from water. In a particularly preferred embodiment of the invention, it relates to a central solar energy receiver assembly for use in the solar tower power plant.

[0002] The present invention relates to a central solar receiver with separated boiler and steam super heater for solar tower thermal power plant.

[0003] The solar energy flux is not a constant or controllable during the operating hours. The solar flux various from daytime to evening, from summer to winter, and from good to bad whether, resulting that received energy density on central receiver is not constant, and is depending on the azimuth angles. The central receiver requires special cares before the optimized performance to cost ratio and high reliability to be reached. A high performance solar centr...
