【正文】 想實現(xiàn)鍋爐安全運行，保證向用戶提供高質(zhì)量的蒸汽 ，減輕工人的勞動強度，減少環(huán)境污染等目的，采用自動控制也是必須的。由此可見， 提高 鍋爐的效率 ，具有十分重要的意義。據(jù)不完全統(tǒng)計，我國共有各類鍋爐近 四十 萬臺，每年的耗煤量達 三 億多噸，占我國原煤產(chǎn)量的三分之一。而燃煤鍋爐又是一種廣泛實用的工業(yè) 鍋爐，廣泛地應用于國民經(jīng)濟各個領(lǐng)域。 工業(yè)鍋爐是工業(yè)生產(chǎn)的重要設(shè)備 ， 往往直接影響生產(chǎn)的正常進行和產(chǎn)品的質(zhì)量、產(chǎn)量和成本。 1 課題研究背景 隨著科學技術(shù)的飛速發(fā)展，帶動社會生產(chǎn)的發(fā)展，人類對能源的需求不斷增加，世界上發(fā)達國家為了解決能源緊張而帶給各行業(yè)的沖擊，都努力在開發(fā)能源的同時，致力于節(jié)能新方案的研究。 intelligent instrument。 關(guān)鍵詞： 過熱蒸汽溫度 ； 智能儀表 ；組態(tài)王 Abstract: Superheated steam temperature is a variety of important industrial boiler equipment parameters, in the production process, the entire path of soft drink is the highest temperature of superheated steam temperature, superheater temperature normal working hours, there are generally closer to the material to allow the maximum temperature, if overheating steam temperature too high, easy to damage superheater and steam turbine will cause excessive internal seriously affected the production of thermal expansion of the safety of operation。同時利用智能儀表控制系統(tǒng)，在所設(shè)計的組態(tài)王監(jiān)控界面中，進行相關(guān)儀表調(diào)校和控制器參數(shù)整定。 本課題利用智能儀表控制系統(tǒng)，結(jié)合組態(tài)王監(jiān)控軟件設(shè)計人機對話界面，實現(xiàn)鍋爐過熱蒸汽控制系統(tǒng)設(shè)計。因此，必須控制過熱器出口蒸汽溫度。 摘 要 ： 過熱溫度是各種工業(yè)鍋爐設(shè)備的重要參數(shù) 。 如果過熱蒸汽溫度過高，則過熱器容易損壞，也會使汽輪機內(nèi)部引起過度的熱膨脹嚴重影響生產(chǎn)運行的安全；過熱蒸汽溫度偏低，則設(shè)備的效率將會降低，同時使通過汽輪機最后幾級的蒸汽濕度增加，引起葉片的磨損。鍋爐過熱 蒸汽溫度 的控制任務，就是為了維持過熱器出口蒸汽溫度在允許的范圍內(nèi)，并保護過熱器管壁溫度不超過允許的工作溫度。通過對現(xiàn)場系統(tǒng)數(shù)據(jù)的采集 處理，在組態(tài)王中實現(xiàn)動畫顯示、報警處理、流程控制、實時曲線和報表輸出等功能。最后向用戶提供鍋爐過熱蒸汽控制系統(tǒng)的動態(tài)運行結(jié)果。 superheated steam temperature is low, it will reduce the efficiency of equipment, while the adoption of the final class of steam turbine steam humidity increased, the wear and tear caused by the leaves. Therefore, we must control the export steam superheater temperature. Overheated steam boiler control is tantamount to the task, that is, in order to maintain the export steam superheater temperature in the permit, and to protect the superheater tube wall temperature does not exceed allowable operating temperature. The subject control system using smart meters, bined with monitoring software Kingview dialogue manmachine interface design, the realization of superheated steam boiler control system design. Through onsite data acquisition and processing system, in achieving kingview animation, alarm processing, process control, realtime curves and the functions of the output statements. At the same time, the use of intelligent instrument control system, designed in Kingview monitoring interface, the associated instrumentation and controls to adjust the setting parameters. Finally, to provide users with superheated steam boiler control system for dynamic results. Key Words: suerheated steam temperature。 Kingview 目 錄 ................................................................................................................................ 1 課題研究背景 ...................................................................................................... 1 課題研究意義 ...................................................................................................... 1 ................................................................................................. 2 2. 系統(tǒng)方案設(shè)計 .............................................................................................................. 3 鍋爐概述 .............................................................................................................. 3 鍋爐的基本構(gòu)造 ....................................................................................... 3 鍋爐的工作原理及過程 ........................................................................... 4 ............................................................................................................. 5 .................................................................. 5 .......................................................................................... 7 ...................................................................................................................... 12 智能儀表概述及選型 ........................................................................................ 12 溫度傳感器概述及選型 .................................................................................... 15 變送器概述及選型 ............................................................................................ 17 執(zhí)行器概述及選型 ............................................................................................ 18 4過熱蒸汽溫度度控制監(jiān)控系統(tǒng)設(shè)計 ........................................................................... 19 組態(tài)軟件概述 .................................................................................................... 19 組態(tài)王概述 ........................................................................................................ 21 過熱蒸過熱蒸汽溫度度控制界面設(shè)計 ............................................................ 22 報警和事件窗口設(shè)計 ........................................................................................ 23 建立數(shù)據(jù)庫連接 ................................................................................................ 24 報表系統(tǒng)設(shè)計 .................................................................................................... 25 5 鍋爐過熱蒸汽控制的動態(tài)運行結(jié)果 .......................................................................... 26 6 結(jié)束語 .......................................................................................................................... 29 參考文獻 .......................................................................................................................... 30 致 謝 .......................................................................................................................... 31 附 錄 .......................................................................................................................... 32 附錄 1：基于組態(tài)王智能儀表鍋爐過熱蒸汽控制系統(tǒng)電氣原理圖 .................... 33 附錄 2：基于組態(tài)王智能儀表鍋爐過熱蒸汽控制系統(tǒng)工藝流程圖 錯誤 !未定義書簽。 鍋爐是化工、冶煉、發(fā)電等作為公用民用部門必不可少的主要動力設(shè)備，其產(chǎn)品是蒸汽， 即 將一次能源（煤炭、石油、提燃氣等）轉(zhuǎn)換為二次能源（蒸汽）。工業(yè)鍋爐又是能耗極大的設(shè)備，在整個工業(yè)生產(chǎn)的能源消耗中占相當大的比重。由于技術(shù)落后、設(shè)備
