節(jié)能雙效濃縮器：一效二次蒸汽作為二效的熱源給物料加熱，再次利用熱能，提高利用率，能有效節(jié)能。
Energy-saving double-effect concentrator: the secondary steam of the first-effect is used as the heat source of the second-effect to heat the materials, which improves the utilization rate of heat energy.
熱泵雙效濃縮器：通過熱泵將一效二次蒸汽壓縮后再提供給二效加熱，從而大量節(jié)約鍋爐蒸汽的使用量，降低生產(chǎn)成本。
Heat pump double-effect concentrator: the secondary steam of the first-effect is compressed by the heat pump and then supplied for the second-effect heating, thus greatly saving the consumption of boiler steam and reducing the production cost.
