| Zusammenfassung: | The invention discloses a method for softening water for boiler steam. The method is characterized in that equipment comprises a boiler, the outlet of the boiler is bidirectionally communicated with a heater through a first pipeline, the air outlet of the heater is communicated with a separator through a second pipeline, and the air outlet of the separator is communicated with a water storage tank through a third pipeline. According to the invention, through the flow matching of the step 1, the step 2, the step 3, the step 4 and the step 5, water in a water storage tank of a boiler can be heated to 90 DEG C or above by utilizing tail steam which cannot be directly recycled into the boiler, and calcium (magnesium) bicarbonate in the water is completely converted into calcium (magnesium) carbonate to be separated out and precipitated at the bottom of the water tank, so that all the water entering the boiler becomes soft water without free calcium and magnesium ions, the purpose of softening the boiler steam wat |
