鍋爐為什麼要使用軟化水

核[object Object]提示:[object Object]經[object Object]軟化[object Object]水[object Object]易于結垢[object Object]由于蒸汽[object Object]斷蒸發[object Object]鍋爐内水[object Object]鈣、鎂、雜質濃度非[object Object]高――[object Object]自[object Object]水[object Object] 30 ― 50 倍[object Object]其結垢[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 )結垢導緻爐壁溫度[object Object]倍升高[object Object]鋼材應力破壞[object Object]強度降低[object Object]嚴重[object Object][object Object]現爆裂[object Object]降低[object Object]使用壽命[object Object]
( 3 )影響蒸汽品質[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]熨鬥等)結水垢、堵塞[object Object]
2 、使用軟化水[object Object]三[object Object]理由:( 1 )《蒸汽(熱水)鍋爐安全技術監察規程》規定所必須[object Object]
( 2 )保持熱效、節約燃料、提高蒸汽品質、延[object Object]壽命[object Object]
其爐膛[object Object]般采用 3 ― 4mm 厚鍋 20# 鋼管[object Object]管内[object Object]水[object Object]管外[object Object]火[object Object][object Object]間[object Object][object Object][object Object]管内壁水垢加厚[object Object]管外[object Object]強火焰[object Object]沖刷[object Object](特别[object Object]側燒立式爐)局部鋼管高溫[object Object]易造[object Object]鋼管爆裂[object Object][object Object]鍋爐内[object Object]結構[object Object]原[object Object][object Object]般[object Object][object Object]焊接修複[object Object][object Object]能報廢[object Object] [object Object][object Object][object Object][object Object][object Object][object Object][object Object]使水軟化[object Object]達[object Object]《鍋規》要求[object Object]1 、自[object Object]水[object Object]加入軟化劑:依據水質化驗結[object Object][object Object]每[object Object]加入适量[object Object]軟化劑[object Object][object Object][object Object][object Object]尺度難[object Object]掌握[object Object]且效[object Object][object Object]般[object Object]佳[object Object]
2 、使用全自[object Object]軟水處理器:工作原理:用離[object Object]樹指[object Object][object Object]吸附水[object Object][object Object]鈣、鎂離[object Object][object Object][object Object][object Object]達[object Object]理想[object Object]軟化水[object Object]目前使
用[object Object]廣效[object Object]較[object Object]、經濟簡便[object Object][object Object]美[object Object]制造[object Object]阿圖祖( AUTOTROL )或福萊克( FLECK )全自[object Object]軟水處理器[object Object]
建議: 使用美[object Object]全自[object Object]軟水處理器[object Object]節約燃料省油省錢 、延[object Object]壽命[object Object]鍋爐質量[object Object]保障[object Object]特别[object Object]立式水管鍋爐[object Object]要配全自[object Object]水質處理器[object Object] 供應商提供[object Object]資料數據[object Object]否規範真實[object Object] ([object Object]油爐[object Object]例[object Object]并[object Object]耗油量[object Object]基準估算)
額定蒸發量( kg/h )≈耗油量× 14 标準産熱量(萬[object Object]卡 /h )≈耗油量× 0.9 供應商提供[object Object]證件應包含[object Object][object Object] 8 [object Object]項 :1、[object Object]産廠制造許[object Object]證(複印件)
2 、鍋爐安全質量監檢證書(原件、複印件[object Object]效)
3 、鍋爐質量證明書(原件、複印件[object Object]效)
4 、強度計算書
5 、安全閥排放量計算書
6 、安裝使用說明書
7 、總圖原件([object Object][object Object]省質技監鍋審字第××号[object Object]批準專用章[object Object]複印件[object Object]效)
8 、本體圖 鍋爐銘牌[object Object]應[object Object]鍋檢所監檢鋼印标記[object Object]
