熱變質煤 的英文怎麼說
中文拼音 [rèbiànzhíméi]
熱變質煤
英文
thermally affected coal-
This article aims at the boiler ' s problems in operation : 1 ) under nominal load, the smoke temperature at the outlet of hearth reaches 1200, far more exceeds 1050 the original designed temperature. this will always result in slag inside boiler and the temperature of overheater ' s pipe superheat, so that boiler cannot take nominal load and all these influence boiler ' s nomal operation heavily, 2 ) this article also studied the reason why the assistant oil becoming necessary when coal changes. during the nomal operation, many factors ( makeup of combustor and its disposal, smirch and encrust of water wall, excessive air coefficient, temperature of primary air, coal type and density of coal dust ) can deviate the designed working conditions, then affect the boiler ' s nomal operation
本文針對該鍋爐在實際運行中存在的問題：在額定負荷下，爐膛出口超溫、低溫段過熱器前煙溫高達936 ，遠遠超過815的設計值；噴燃器四周水冷壁結焦嚴重，過熱器管壁溫度超標，無法帶上額定負荷；甚至有時因燃煤質量的變化，必須投油助燃的嚴重情況進行了分析研究。在實際生產過程中，燃燒器的結構、布置，水冷壁的粘污、結垢，過剩空氣系數、一次風溫、煤種及其濃度變化等許多因素都會偏離鍋爐的設計工況，從而影響爐內的傳熱和燃燒，造成爐膛出口超溫、水冷壁結渣等問題。Medium - rank bituminites are formed by pneumato - hydrothermal metamorphism on the basis of burial metamorphism, and it is partial
深大斷裂帶及其附近局部發育的中級煙煤是在深成變質基礎上，疊加了高溫氣液熱變質作用而形成。Synthetically analyzed the fracture, earthquake, coal ranks and their distribution, coal seam ' s buried depth and so on, the authors have realised that low - rank bituminites, early - middle jurassic in tianshan area, are formed by burial metamorphism, and it is widespread
摘要通過對天山地區的斷裂構造、地震、地熱、煤級及其時空分佈、煤層埋深等因素的綜合分析，認為天山北緣及其鄰區早中侏羅世大范圍分佈的低級煙煤主要由深成變質作用形成，深成變質作用具普遍性。Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite, vitrinite and fusinite from jurassic coals in tarim basin at different temperatures. the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds. vitrinite is mostly composed of aromatic compounds, in addition to large amount of short aliphatic - side chain compounds. whereas fusinite are dominant by aromatic structure. the study indicates that cutinite is one of the best oil source - rocks, with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks, and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential. in addition, the components of aliphatic structures of cutinite, vitrinite and fusinite decrease, the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature, and along with the rise of temperatures, the intensity of aliphatic structure and heteroatomic compounds decrease obviously, however the aromatic structure changes a little
應用顯微紅外光譜技術，對塔里木盆地侏羅紀煤中有代表性的3種組分角質體鏡質體絲質體在不同熱模擬溫度下的結構組成變化特徵進行了研究，結果表明：角質體結構組成中含有較豐富的長鏈脂族結構，而芳香結構和含氧官能團的含量則相對較少與此相反，絲質體結構組成中芳香烴占絕對優勢，而脂族結構含量則很少鏡質體結構組成介於角質體和絲質體之間，含有較多的短鏈脂族結構和芳香結構。This is a model of telemagmatic metamorphism and a character of coal metamorphism early - middle jurassic in northwest of china
屬于區域巖漿熱變質作用的一種模式，也是西北地區早中侏羅世煤變質的特點之一。Thus clean factor has good adaptability to boiler load, coal quality, excess air coefficient, working medium flow, and boiler efficiency etc. the calculated result gained by inputting the data of history database of the object boiler validates the correctness and adaptability to boiler load of clean factor model
基於穩態傳熱的清潔因子灰污監測模型，對鍋爐負荷、燃煤品質、過量空氣系數、各類工質流量、燃煤量和鍋爐熱效率等的波動變化有很好的適應性。以北侖電廠1 #爐歷史庫中數據為輸入數據，驗證了清潔因子模型的正確性和對穩定負荷的適應性。In our country, the quality of coal for utility boiler is low and varying too much, the boiler capacity and efficiency of combustion are reduced by 20 % and 2. 5 % respectively because of slagging
在我國，電站鍋爐燃用煤質較差，且煤質多變，由於結渣而降低出力和熱效率達20和2Abstract : the resource characteristics such as the composition, texture, structure and the prospects of industrial utilizations included white carbon black, alc13, 4a zeolite, al - si alloy and rubber filler of coal - series kaolinite in huainan and huaibei mining area were introduced
