Learn MoreAlthough the solar energy captured by flat plates is low-grade (50–100 C), the use of this energy in lignite drying saves high-grade furnace energy (approximately 1200 C). This high-grade energy, originally intended for moisture evaporation, can be used to generate more high-grade live and reheat steams at temperatures exceeding 500 °C.
