The energy costs of an evaporator can be significantly reduced by using waste heat resources like hot water.
The energy costs of an evaporator can be significantly reduced by using waste heat resources like hot water.
Instead of using heating steam a multiple effect evaporation plant can be heated by hot water.
Hot water resources could be:
Another liquid heat source could be thermal oil.
The energy costs of an evaporator can be significantly reduced by using drier vapor for heating.
In case of multiple-effect evaporation plants, the exhaust vapor from the product are used to heat the downstream-arranged evaporation effect so that the steam consumption will be reduced accordingly.
机械蒸汽再压缩机 (MVR) 加热的蒸汽设备只需要特别少的能量。
使用热力蒸汽再压缩机 (TVR),和其他蒸发方法一样节省蒸汽/能源。
传统上,使用直接蒸汽加热的蒸发器有单效和多效之分。通常使用新鲜蒸汽作为能量来源,但是也可以使用废热(如干燥机蒸汽)。
