Project: TubeMon - New online flux density and temperature measuring systems for MONitoring and optimized operation of external TUBE receivers

Acronym TubeMon (Reference Number: JTC-2_2019_050)
Duration 01/09/2019 - 31/08/2022
Project Topic Solar power towers offer the highest cost reduction potential among all CSP technologies. Raising the receiver efficiency and extending its lifetime are suitable measures to reduce the electricity generation costs. In order to do that, the flux density and the temperature distribution have to be measured and controlled. Previous measurement methods suffer from severe disadvantages. The moving bar technique for measuring the flux density distribution is hardly feasible for large-scale receivers due to high efforts and costs. Formerly used thermography methods assume a constant emissivity and ignore the receiver's aging and spatial inhomogeneities. The TubeMon project is a key for overcoming these limitations and boosting the enhancement of measuring systems, simulations and control for industrial-scale external tube receivers. It puts emphasis on the improvement of a promising flux density measurement technique and will lead it to application at large tubular receivers. Emissivity and thermographic temperature measurement will substantially gain accuracy. Demonstrational tests at a commercial power plant pave the way for posterior application and commercialization of the technologies. Progress in raytracing, modeling and control of flux and receiver operation supplement the project very well. The project is carried out by a strong trinational consortium, bringing together experts of industry and science. Together, they make a significant contribution to the decrease of CSP costs.
