Multi-effect evaporation complete equipment

A kilo of steam condensation releases heat and a kilogram of water evaporation need to absorb heat, is basically the same, so the single efet evaporation, evaporation material by one kilo of water, need to consume a kilo of firesh steam; if the evaporation of the two steam is used as a effective heating steam, two. Steam, steam consumption than single effect saves 50%. The effect increases, steam to reduce equipment investment, but increased a lot, so is generally not more than 5.
