2 清徐縣位于山西省中部，是省城太原的南大門。 208、 307兩條國道、青銀高速公路和正在建設(shè)中的太中銀鐵路穿境而過，交通便利，土地肥沃，水系密布，湖泊眾多。全縣總面積 609平方公里，轄 4鎮(zhèn) 5鄉(xiāng) 1個街道辦事處、 192個行政村和 6個社區(qū)居委會，常住人口 34萬，享有“文化名城 醋都葡鄉(xiāng)”的美譽。 清徐古稱梗陽，始建于春秋，歷史悠久，人文薈萃，迄今已有 2500多年的歷史，是古典文學名著三國演義作者羅貫中的故里。堯城村曾是堯帝建都之地，因此有 “中華第一都”之稱。清徐也是晉商的重要組成部分，至今徐溝、大常、賈兆等地尚有保存相對完整的晉商古民居和古村落。全縣共有國家級文物保護單位 2個、省級 4個、市級 6個，其中，國家級文物保護單位狐突廟、清源文廟享譽全國，省級文物保護單位香巖寺、千佛洞是中國北方地區(qū)佛教石窟藝術(shù)的代表。清徐還是中國民間藝術(shù)之鄉(xiāng)，徐溝背鐵棍藝術(shù)被譽為“空中舞蹈、 流動雜技、無言戲劇”，是省級非物質(zhì)文化遺產(chǎn)。 清徐有中國葡萄之鄉(xiāng)之稱。“清徐有葡萄，相傳自漢朝”。清徐葡萄種植歷史悠久，所產(chǎn)的龍眼葡萄皮薄、味甜、營養(yǎng)豐富，是鮮食、釀酒的佳品，被中國特產(chǎn)之鄉(xiāng)評審委員會評為中國葡萄之鄉(xiāng)。全縣葡萄種植面積 5萬畝，葡萄品種超過 160個。成為全國傳統(tǒng)四大葡萄名產(chǎn)地之一。地處白石溝山區(qū)的葡峰山莊生態(tài)環(huán)境優(yōu)良，葡萄漫山遍野，吸引了無數(shù)游人慕名而來，現(xiàn)已成為國家級農(nóng)業(yè)生態(tài)旅游示范點。同Selection.ParagraphFormat.LineSpacingL inesToPoints(2)

1924年巴拿馬國際商品博覽會優(yōu)質(zhì)商品一等獎?，F(xiàn)有老陳醋、陳醋、熏醋、白醋、保健醋、風味醋六大系列 60多個品種。是全國最大的老陳醋生產(chǎn)基地，被中國特產(chǎn)之鄉(xiāng)評審委員會命名為中國陳醋之鄉(xiāng)。 1.4項目建設(shè)的必要性 太原玉盛源能源發(fā)展有限公司 集團有限公司緊鄰

5 第二章 燃料及熱負荷 2.1 燃料 2.1.1燃料來源 本工程為 太原玉盛源能源發(fā)展有限公司 焦爐煤氣綜合利用工程，本工程采用燃氣鍋 爐，鍋爐燃料為 周邊 焦化廠副產(chǎn)的焦爐煤氣。 焦化廠主要工藝流程如下： 由備煤車間來的洗精煤，由輸煤棧橋運入煤塔，裝煤推焦機行至煤塔下方，由搖動給料機均勻逐層給料，用 21錘固定搗固機分層搗實，然后將搗好的煤餅從機側(cè)裝入炭化室。煤餅在 950-1050的溫度下高溫干餾，經(jīng)過約 22.5小時后，成熟的焦炭被推焦車經(jīng)攔焦車導焦柵推出落入熄焦車內(nèi)，由熄焦車送至熄焦塔用水噴灑熄焦，熄焦后的焦炭由熄焦車送至晾焦臺，經(jīng)補充熄焦、晾焦后，由刮板放焦機放至皮帶送焦場。熄焦塔處設(shè)光電自動控制器，通過控制器中的時間繼電器調(diào)整噴灑時間， 保證紅焦熄滅。熄焦后的焦炭卸至晾焦臺上，冷卻一定時間后送往篩貯焦工段。 干餾過程中產(chǎn)生的荒煤氣經(jīng)炭化室頂部、上升管、橋管匯入集氣管。在橋管和集氣管處用壓力為約 0.3MPa，溫度約 78的循環(huán)氨水噴灑冷卻，使約 700的荒煤氣冷卻至 84左右，再經(jīng)吸氣彎管和吸氣管抽吸至冷鼓工段。在集氣管內(nèi)冷凝下來的焦油和氨水經(jīng)焦油盒、吸氣主管一起至冷鼓工段。 從煉焦車間來的焦油氨水與煤氣的混合物約 80入氣液分離器，Selection.ParagraphFormat.LineSpacingL inesToPoints(2)

100mg/Nm3以下，煤氣經(jīng)捕霧段除去霧滴后全部送至硫銨工段。 由脫硫及硫回收工段送來的煤氣經(jīng)煤氣預熱器后進入噴淋式飽和器上段的噴淋室，在此煤氣與循環(huán)母液充分接觸，使其中的氨被母液吸收。煤氣經(jīng)飽和器內(nèi)的除酸器分離酸霧后送至洗脫苯工段。 來自硫銨工段的 粗煤氣，經(jīng)終冷塔冷卻后從洗苯塔底部入塔，由下面上經(jīng)過洗苯塔填料層，與塔頂噴淋的循環(huán)洗油逆流接觸，煤氣中的苯被循環(huán)洗油吸收，再經(jīng)過塔的捕霧段脫除霧滴后離開洗苯塔，其中一部分送焦爐做回爐煤氣，一部分送粗苯管式爐作燃料，剩余部分送熱電廠發(fā)電。 為綜合利用焦爐剩余煤氣，同時解決全廠生產(chǎn)、生活、采暖等用蒸汽的需要，本工程擬建設(shè)一座綜合利用自備熱電廠。遵照國家計委“關(guān)于鼓勵發(fā)展小型熱電聯(lián)產(chǎn)和嚴格限制凝汽式小火電建設(shè)的若干規(guī)定”的精神，本設(shè)計采用熱電聯(lián)產(chǎn)的方案。在滿足供熱需要的前提下，多發(fā)電。這不僅具有
