Modeling, simulation and outdoor experimental performance analysis of a solar-assisted process heating system for industrial process heat

Industrial process heating applications in the temperature range of 50 degrees-250 degrees C consumes about 35% of the global fossil fuels, wherein solar thermal is envisaged as an alternative option. Outlet temperatures of both flat-plate collector (FPC) and photovoltaic thermal collector (PVT) are...

Q Science (General) T Technology (General) Industrial process heating applications in the temperature range of 50 degrees-250 degrees C consumes about 35% of the global fossil fuels, wherein solar thermal is envisaged as an alternative option. Outlet temperatures of both flat-plate collector (FPC) and photovoltaic thermal collector (PVT) are not high enough to serve industrial processes.

This well-engineered integration offers unique and sustainable solution to meet industrial process heat demand at a minimum fossil fuel usage. Such SAPH system with the compatible numbers of FPCs and PVTs can be implemented to accomplish low to medium temperature process heat requirements. (c) 2020 Elsevier Ltd. All rights reserved.
