In the design of the boiler room when the water softening system, the device of water softening, softening tanks, the device that removes oxygen , circulating pumps, pumping up the water automaticly are in accordance with the relevant values of the calculation and under the selection. The entire puter automatic control systems enable to transport the coal, automatic softening water system, and automatic desecrator. The system is so automatic and high intelligenced that the management and the repair latter. The water is used in rinsing the slag。 number of boilers and models。 我對鍋爐房內(nèi)的輔機設(shè)備進行選擇計算。 本次鍋爐房設(shè)計從搜集 參考資料 開始 。 在設(shè)計這個鍋爐房時 ,對水系統(tǒng)的軟化設(shè)備,軟化水泵,軟化水箱,除氧設(shè)備,除氧水箱,循環(huán)水泵,補水泵的選擇都是按照有關(guān)的規(guī)定的進行計算和選擇的。整個系統(tǒng)采用計算機進行自動控制,實現(xiàn)了對聯(lián)合上煤、全自動軟化水系統(tǒng)、自動除氧、自動補水的自控。資料包括 鍋爐房建設(shè)地點的 氣 象、地理、水電資料。 我 根據(jù)計算繪制鍋爐房設(shè)備布置平面圖、鍋爐房水管布置平面圖和剖面圖,繪制鍋爐房水系統(tǒng)原理圖和設(shè)備安裝大樣圖。 boiler room water systems, drums, induced draft fan system, the removal system of the coal slag, the design of the system that removes the coal slag and the selection of device。 the slag is removed directly, in order to protect the environment near the boiler house. The design of the boiler room was beginning when I collected a variety of design reference books and reference datum. The datum includes the location of the boiler room, and the information of geography, water, electricity. I determine the type of the boiler with hot type and the user. I determine the capacity of the boiler according the total heat load. The design includes the calculation of the boiler39。 4 3 熱負荷計算及鍋爐選擇 .............................................................................................................. 5 熱負荷計算 ............................................................................................................................... 5 采暖季最大計算熱負荷 6 鍋爐型號與臺數(shù)確定 ............................................................................................................... 7 燃料 種類的確定 7 鍋爐參數(shù)的確定 8 鍋爐的選型 9 4 給水及水處理設(shè)備的選擇 ........................................................................................................ 11 給水設(shè)備選擇 ......................................................................................................................... 11 鍋爐房補給水量的計算 12 鈉離子交換器的選擇和計算 19 鍋爐房運煤方式的選擇 ...................................................................................................... 19 除渣方式的選擇 .................................................................................................................. 20 煤場和灰渣場面積的確定 20 煤場面積的確定 23 省煤器的阻力 23 除塵器的阻力 23 煙囪抽力和煙道阻力 23 煙氣除塵設(shè)備的選擇 24 煙囪設(shè)計計算 24 8 供暖熱水鍋爐房內(nèi)監(jiān)測與控制 ................................................................................................ 25 供暖熱水鍋爐房內(nèi)監(jiān)測與控制的主要目的 ......................................................................... 25 燃燒系統(tǒng)監(jiān)測與控制 25 鍋爐房水系統(tǒng)的監(jiān)測控制 32 防腐 ......................................................................................................................................... 33 10 鍋爐房布置 .............................................................................................................................. 34 11 鍋爐房人員的編制 .................................................................................................................. 35 12 設(shè)計技術(shù)經(jīng)濟指標 .................................................................................................................. 36 工程概預(yù)算 ........................................................................................................................... 36 工程概預(yù)算的定義 盡管 目前我國鍋爐房使用天然氣的前景十分廣闊,但是在哈爾濱地區(qū) , 天然氣價格較貴, 且 靠近我國主要煤產(chǎn)區(qū),因此燃煤較天然氣更經(jīng)濟。 設(shè)計概述 本設(shè)計為一熱水 采暖 鍋爐房,為住宅提供熱水。季節(jié)性熱負荷的特點是:它的大小與室外溫度、濕度、風(fēng)向、風(fēng)速和太陽輻射熱等氣候條件密切相關(guān),其中對它的大小起決定性作用的是室外溫度,因而在全年中有很大的變化。 采暖設(shè)計熱負荷 工業(yè)建筑采用體積熱指標,民用建筑采用面積熱指標 。hQ ——建筑物的供暖設(shè)計熱負荷, w; hQ——建筑物的供暖體積熱指標, w/ m3hQ = AQh ( 22) 式中 39?!? 建
