核[object Object]提示：[object Object]經(jīng)[object Object]軟化[object Object]水[object Object]易于結(jié)垢[object Object]由于蒸汽[object Object]斷蒸發(fā)[object Object]鍋爐內(nèi)水[object Object]鈣、鎂、雜質(zhì)濃度非[object Object]高——[object Object]自[object Object]水[object Object] 30 — 50 倍[object Object]其結(jié)垢[object Object]速度超[object Object][object Object]我[object Object][object Object]想象[object Object][object Object]需半[object Object]至[object Object][object Object][object Object][object Object][object Object]結(jié)垢 1 — 2mm [object Object]水垢[object Object]危害極[object Object][object Object]嚴重[object Object][object Object][object Object]引起鍋爐爆裂[object Object]水垢[object Object]金屬[object Object]導熱性能[object Object]比[object Object]
水垢導熱性能[object Object][object Object]金屬[object Object] 0.5% 左右[object Object][object Object]鍋爐結(jié)垢[object Object][object Object]要想達[object Object][object Object]水垢[object Object][object Object]熱效[object Object][object Object]要提高受熱面[object Object]溫度[object Object][object Object]：爐壁溫[object Object] 250 ℃[object Object] [object Object]結(jié)垢 1mm [object Object][object Object]要達[object Object]同[object Object][object Object]熱效[object Object]壁溫要提高[object Object] 650 ℃[object Object][object Object][object Object]熱吸收率極低[object Object]能耗增加[object Object]
1 、水垢主要[object Object]三[object Object]危害：（ 1 ）減少熱吸收[object Object]降低鍋爐熱效率[object Object]浪費燃料[object Object][object Object][object Object]增加鍋爐運行[object Object]本[object Object]
（ 2 ）結(jié)垢導致爐壁溫度[object Object]倍升高[object Object]鋼材應(yīng)力破壞[object Object]強度降低[object Object]嚴重[object Object][object Object]現(xiàn)爆裂[object Object]降低[object Object]使用壽命[object Object]
（ 3 ）影響蒸汽品質(zhì)[object Object]使蒸汽[object Object]含鈣、鎂離[object Object]、易使鍋爐配件（安全閥、壓力表、壓力控制器等）、蒸汽器械（[object Object]熨斗等）結(jié)水垢、堵塞[object Object]
2 、使用軟化水[object Object]三[object Object]理由：（ 1 ）《蒸汽（熱水）鍋爐安全技術(shù)監(jiān)察規(guī)程》規(guī)定所必須[object Object]
（ 2 ）保持熱效、節(jié)約燃料、提高蒸汽品質(zhì)、延[object Object]壽命[object Object]
