WebMar 6, 2024 · Solar steam evaporation (SSE) is a new low-cost, energy-saving and environmentally friendly device as well as a new method for obtaining freshwater resources (Yang et al. 2024; Chen et al. 2024; Fu et al. 2024 ). Due to its internal transpiration structure, wood as a green natural resource can achieve moisture transport inside the … WebThe vapor-compression evaporation process replaced the once-through steam generators (OTSG) traditionally used for steam production. OTSG generally ran on natural gas which in 2008 had become increasingly valuable. The water quality of evaporators is four times better which is needed for the drum boilers. plbymvs03.ww930.my-it-solutions.net
