Dynamic Simulation of Mono-tube Cavity Receivers for Direct Steam Generation
The ANU 500 m dish has been in operation since 2010 with a mono-tube steam cavity receiver, the SG4 system for the production of steam used for electricity generation. Dynamic modelling of this system is crucial for achieving robust control and optimised performance. This paper presents ongoing work with the dynamic modelling and simulation of a mono-tube steam cavity receiver for direct steam ...
متن کاملBuffer storage for direct steam generation
Fast reaction times and high discharge rates make steam accumulators a promising option for compensation of fast transients in insolation for solarthermal systems using steam as working medium. Using the volume of components like separator drums or heat exchangers for storage of pressurized hot water is a cost-effective approach to integrate buffer storage capacity. While the basic steam accumu...
متن کاملDesign Considerations for Direct-Conversion Receivers
This paper describes the issues and tradeoffs in the design and monolithic implementation of direct-conversion receivers and proposes circuit techniques that can alleviate the drawbacks of this architecture. Following a brief study of heterodyne and image-reject topologies, the direct-conversion architecture is introduced and effects such as dc offset, I=Q mismatch, even-order distortion, flick...
متن کاملDirect Steam Generation with Dish Concentrators
This paper presents current research on Direct Steam Generation (DSG) by the Solar Thermal Group at ANU. It includes ongoing work on a transient model for a dish steam cavity receiver that is suitable for model-based control of DSG as well as reporting on the experimental set-up on a new 500m paraboloidal dish solar concentrator. A comparison of two transient models of a dish steam cavity recei...
متن کاملDIRECT STEAM GENERATION USING THE SG4 500m PARABOLOIDAL DISH CONCENTRATOR
The ANU 500 m dish is the first prototype of a new design geared towards mass production and low levelised cost of energy. The dish has high quality optics, with a geometric concentration ratio above 2200, and can be used for a variety of energy conversion technologies. The SG4 concentrator is currently being operated in direct steam generation mode with a monotube steam receiver. Experimental ...
