The operational conditions of the solar-thermal receiver for a Brayton cycle engine are challenging, and lack a large body of operational data unlike steam plants. We explore the receiver's fundamental element, a pressurized tube in time varying solar flux for a series of 30 yr service missions based on hypothetical power plant designs. We developed and compared two estimation methods to predict the receiver tube lifetime based on available creep life and fatigue data for alloy 617. We show that the choice of inelastic strain model and the level of conservatism applied through design rules will vary the lifetime predictions by orders of magnitude. Based on current data and methods, a turbine inlet temperature of 1120 K is a necessary 30-yr-life-design condition for our receiver. We also showed that even though the time at operating temperature is about three times longer for fossil fuel powered (steady) operation, the damage is always lower than cyclic operation using solar power.

Abstract The food processing industry exists at the nexus between food, energy, and water systems. Improving the sustainability of this industry is critical to reduction of carbon emissions and enhanced utilization of vital resources such as water. The overarching aim of the present research is to create a process-based modeling platform for food processing systems that would allow the most appropriate combination of water-sustainable, energy-efficient, and renewable energy (WERE) technologies to be determined for a system. This paper focuses on one specific process in a thermal processing line: the cooling step after sterilization and prior to packaging. A typical process might use groundwater in a once-through loop. To reduce water use, two sustainable alternatives are considered and compared: (a) solar thermal coupled with an absorption chiller and (b) evaporative cooling of chilled water using a sub-wet bulb evaporative chiller (SWEC). The former uses a parabolic trough solar field with thermal storage that is connected to a single-effect water/lithium bromide (LiBr) chiller. The field and thermal storage are modeled using NREL’s System Advisor Model software and coupled to in-house Python code for the chiller and process heat exchanger. For the latter option, a novel SWEC is used as a chiller. The energy and water use, and capital cost of the two alternative technologies are presented.
