Dynamic Simulation of Mono-tube Cavity Receivers for Direct Steam Generation
نویسندگان
چکیده
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 generation. A ray-tracing study of the heat flux distribution inside the steam receiver is used to spatially refine the model and improve its accuracy for large transients. A subdivision of the dynamic model into sub-models is proposed and a simulation is presented to support this approach. Initial modelling results show qualitative agreement with experimental data, and the model will be progressively expanded to cover the full range of possible operational scenarios.

Estimation of Outlet Mass Flow for a Mono-tube Cavity Receiver for Direct Steam Generation
This paper presents recent developments on a dynamic model for a mono-tube cavity receiver for direct steam generation with large scale parabolic dishes. Simulations of the model show that it is possible to assume a homogeneous distribution of heat flux along the receiver pipe without loosing accuracy in the calculation of receiver outlet temperature. The model in its current state produces an ...
متن کاملA Modified Extended Kalman Filter to Estimate the State of the SG4 Receiver at the Australian National University
The temperature control of direct steam generation depends on information about the dynamic heat transfer behaviour of the receiver during operation. This information may come from sensors or dynamic mathematical models of the heat transfer process taking place at the receiver. In practice, sensors are susceptible to noise and calibration errors and models suffer from uncertainty due to inexact...

متن کاملSimulation of a Solid Oxide Fuel Cell with External Steam Methane Reforming and Bypass
Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
