Stoichiometric air fuel ratios of automotive fuels 汽車燃料的化學(xué)計算空氣燃料比
Some fossil fuels , however , are less damaging than coal 然而,一些礦物燃料比煤的污染要小。
First , the recycled fuel is more expensive than the original uranium 首先,再循環(huán)使用的燃料比原來的鈾更貴。
Ar air regulators in multiple burner systems , hold constant air - fuel ratio and the mixture pressure with reducing burner port area of up to 90 % Ar空氣調(diào)節(jié)閥用于多爐頭系統(tǒng),保持恒定的空氣燃料比和混合氣壓力。
Georgia went through the worst inflation in 1994 . in 1993 , the highest denomination was 100 , 000 laris . by 1994 , the highest denomination was 1 , 000 , 000 laris . in the 1995 currency reform , 1 new lari was exchanged for 1 , 000 , 000 laris 德國在1923年至1924年間的惡性通貨膨脹的寫照:一名德國女子以鈔票代替木柴作為壁爐用的燃料,因為在事實上,當(dāng)時直接以鈔票作為壁爐燃料比使用木柴來得更加劃算。
Ruburning with coal has been proved a effective low nox emission combustion technology 。 in this ph . d thesis , the reaction mechanisms of reburning have been investigated , and the homogeneous and heterogeneous reduction of nox have been analyzed in details . a series of reburning experiments have been carried out on an entrained - flow reactor , in which two kinds of coals with different particle sizes have been used 本文對煤粉再燃過程中,揮發(fā)分及煤焦的基元反應(yīng)途徑和反應(yīng)機理進行了詳細分析;在攜帶爐實驗臺上進行了神華煤、邢臺煤在1200與1300 、四種煤粉細度、三種再燃燃料比和三種再燃區(qū)初始氧量,共144個實驗工況下的再燃實驗。
Abstract : the air / fuel ratio control scheme in common use of boiler auto - burning system is introduced summary . two kinds of scheme improved to obtain the best air / fuel ratio and to raise dynamic characteristic are analyzed in particular . further how to correct measures on air / fuel ratio when changing boiler load and fuel composition is proposed and analyzed 文摘:對鍋爐自動燃燒系統(tǒng)中空氣/燃料比控制的常用方案進行了簡要介紹,著重分析了兩種為獲取最佳空氣/燃料比和提高控制系統(tǒng)動態(tài)特性而采取的改進方案,并針對鍋爐負荷變化和燃料特性改變對燃燒狀況的影響,進一步對空氣/燃料比的修正措施進行了分析與探討,提出了綜合修正方案。
