“…This is less expensive than alternative drying methods like electric or gas-fired dryers. By substituting solar drying for fossil fuel-based drying, greenhouse gas emissions can be decreased [ 114 , 119 ]. Walz et al [ 120 ] analyzed that P.T.C is an efficient heating device and can be used for portable dryer machines.…”

“…The experiment (Figure 7) found that the attachment of the heat exchanger and evacuated tubes ensured the maximum distillate productivity at 4 cm water depth. Chaanaoui et al [61] conducted a comparative analysis for fin configuration on the performance of solar drying applications. A fin tube-type heat exchanger was used for experimental study, as shown in Figure 4.…”

Solar desalination is a process to convert saline water into potable water by the application of solar energy. The enhancement of the distillate output of the solar desalination is low, so it is not considered as a method to produce potable water. A heat exchanger is an important device used for heat transfer applications. The present review article illustrates the application of a heat exchanger with a solar desalination system to enhance the distillate output. In the current review, it is found that the heat exchanger is an important device to improve the distillate productivity of the solar desalination system. Finally, the future work and future challenges of using a heat exchanger with a solar desalination system are presented.

“…Figure 9 shows thermal imaging of the operating dryer during testing in solar mode, where the inlet air temperature was 100 °C. To achieve solar heating of the inlet air, the rotary dryer was coupled to a parabolic trough [13] system via a finned tube heat exchanger designed [14,42] for this solar application.…”

“…This would allow their reuse to process phosphate sludge after some adaptation, with the required drying energy supplied by fossil fuels. Solar thermal energy could, however, be a possible ecofriendly alternative [13,14]. To the best of our knowledge, this study is the first of its kind to study the drying of phosphate washing sludge by a rotary kiln.…”

As an eco-friendlier way to manage mining waste, the use of solar energy to dry phosphate sludge in a rotary dryer is envisioned. As a first step toward this end, a design study for a bench-scale rotary dryer for phosphate sludge is detailed, using a one-dimensional mathematical model developed for this task. Using the Engineering Equation Solver (EES) software, a steady-state transport phenomena model was developed that enables an estimation of the moisture and temperature profiles for both gas and product in the dryer. A sensitivity analysis evaluated the effects and influence of different geometric parameters and operating conditions on the product moisture profile. Parameters involved include the diameter of the dryer, the residence time of the product to dry, inlet air temperature, and inlet product humidity. This allowed for the selection of suitable design parameters for the operation of a phosphate sludge dryer with a 1.5 m length and an internal diameter of 11.5 cm. The inlet air temperature of the rotary dryer was set at 200°C to achieve a reduction of moisture content in the product from 30% to 7%. The model was validated through literature and experimental datasets, with an error averaging 0.22% and 1.52%, respectively.
