Aiming at such problems in combustion system of homemade middle and miniature boiler, as a complex system with the character of dead zone, time variation, serious non - linearity, large time delay, coupling and a lot of disturbance, this paper presents a new set of optimal control resources. by using well - matched control method on system, stable automatic running is realized. having the serious divulgence coals difference a lot from each other in character, instability of chemistry, value of lowest emission of heat, home - made boiler controller is not at all ideal. instead of traditional model that controls the ratio based on proportional control or with the correct signal of the amount of oxygen, this paper, combined with intellect control theory - - fuzzy control and self - optimizing concept, propounded a kind of fuzzy self - optimizing controller to be used in air supplying system of the boiler, and expatiates on the idea of dividing the control process into two parts, dynamic and static to realize, thus meets the demand of homemade boiler economic running
本設計針對國產中、小型電站鍋爐燃燒系統參數時變、嚴重非線性、干擾因素復雜、耦合嚴重、模型不易確定的特點,提出多變量協調控制方案,解決了系統可控性差,難以實現穩定自動運行的問題;在此基礎上,改變以往以煙氣含氧量控制送風的傳統模式,針對國產電站鍋爐設備主體及一、二次送風迴路泄露嚴重,煤種混雜、成分不穩定、燃燒發熱值低、燃燒效率不高等問題,應用智能控制理論中的模糊控制技術,結合自尋最優控制的思想,設計了一種模糊自尋優控制器,應用在電站鍋爐送風控制系統上,並闡述了動靜態兩種實現途徑,通過在線優化風煤配比,實現最佳經濟燃燒,切實保障了鍋爐的經濟運行。In the construction industry there has always been a mismatch between the research investment and construction expenditure and this has lead the industry to proceed on a scale with an inadequate understanding of many aspects of construction, such as, deterioration mechanism for structures that has often meant that due allowance has not been made for practical repair and maintenance. however, notwithstanding this situation there have been encouraging signs that within the last twenty years the transition from the conventional materials to the more advanced materials is being spear - headed by the construction industry where over 30 of all polymers produced are now utilised in that industry
水工建築物是社會各建築群體中的一類,是所在地環境的一個有機組成部分,隨著經濟社會的發展,水工建築物的外觀越來越受到重視.水工建築物的外觀質量控制主要在設計與施工兩個環節.外觀設計的質量表現在建築物滿足運行功能要求的情況下,既方便施工,又具有特色.施工的質量表現在建築物的實施效果.常見的外觀質量缺隙主要有蜂窩麻面、色澤不一、氣泡偏多、表面平整度差等,應從施工工藝、建築材料的質量等方面加以控制The thesis was written under the direction of dynamic theory of forming reservoir, follows the rules of comprehensive information, judgment, interpretation and assessment and even makes full use of outcrop geology, data from drilling and logging, data from laboratory analysis and achievements in geophysical exploration. considering the basic factors of forming reservoir in the south of ordos basin as the starting point, the thesis defines that yanchang group of triassic goes into the start of generating oil in the late period of mid - jurassic and that the largest oil generation peaks in the middle period of early cretaceous, after the analogue - history of hydrocarbon generation. meanwhile it also establishes the relationship between the evolution of oil and gas and the formation of traps, the time of oil exploration
本文以成藏動力學理論為指導,本著綜合信息、綜合判斷、綜合解釋、綜合評價的原則,充分利用露頭地質,鉆測井資料,實驗分析資料及物化探成果,以鄂爾多斯盆地南部的基本成藏要素為出發點,通過生烴史模擬,確定了三疊系延長組在中侏羅晚期( 150ma )進入生油門限,于早白堊世中期達到最大生油高峰期;同時並確立了油氣演化與圈閉形成、捕油時間的關系;通過流體勢的全區計算,提出了該區油勢具有明顯的「雙層」結構特徵,並建立了以靜水壓力為主的重力流系統和以差異壓實作用為主的壓實流系統的流體動力分佈模型;通過成藏動力學系統的劃分及事件分析,探討了該地區油氣聚集規律,最終指出了有利的含油氣遠景區。Through having done field surveys in the campus of chongqing university, this paper tested classroom indoor and outdoor climate parameters in june, july and september of 2005, it used questionnaire to acquire subjects ’ thermal sense, draft sense and humidity sense in classroom each month, and programmed composition to compute predicted mean vote and compared pmv with the field testing results of mean thermal sensation vote. it is discovered that pmv is overvalued the college student ’ thermal sensation in chongqing. it finds that people in chongqing adapt to the typical summer hot and winter cold sweltering weather
對重慶地區高校教室的現場調查,測試了重慶大學2005年六月、七月和九月教室室內外熱環境參數,通過採用問卷主要掌握了受測對象教室里的冷熱感、氣流感和潮濕感,通過編製程序求得預測平均熱感覺評價pmv的值,比較pmv和問卷調查得到的平均熱感覺mtsv ,發現pmv預測值高估了重慶地區高校學生的熱感覺,這里的人群對重慶這種夏熱冬冷地區比較典型的悶熱氣候具有一定的熱適應性,對現場問卷調查的結果進行分析,得出了室內空氣溫度、氣流速度、相對濕度與人體主觀感覺之間的回歸曲線,發現重慶地區高校學生熱中性時的空氣溫度為25 . 5 , fanger根據歐美人群調查得到的公式計算出的預測熱感覺為中性時的空氣溫度為25 . 0 ,兩者相差0 . 5 。Using cfx4. 3 code with finite difference and simplec methods, the temperature distribution of ladle lining baked at different preheating temperature of combustion gas was studied numerically and experimentally
