    通過對樣機的試驗分析和研究表明，汽車空氣燃油加熱器在整個工作過程中，其排放存在以下三個問題：一、開機和關機兩個階段的排放問題嚴重，廢氣中hc和co的濃度值及煙度測量值都很高；二、因點火系統和燃燒結構的缺陷而導致開機后一段時間內有油滴從滴油管滴落；三、在點火過程中，會出現因操作不當而點火失效的現象。
  2. With analyzing of the case study and based on simulating and analyzing quantitatively, this article, considering the goal of the performance - based fire - protection design is protecting occupants from being injured and keeping buildings from being damaged, thought that fire compartmentation of a large building of saling books can be divided according to their saling malls and fire compartmentation in the saling mall can be separated by the fire - proof screen. on the evacuation design, the quantity of safety exits around these buildings and the evacuation width should be increased if possible and the safety exit number, exit width and evacuation distance can be determined according to the simulating results on smoke layer temperature and height, concentration of co2 and co, occupants evacuation time and visibility. on the means of preventing and discharging smoke, the most proper measure should be determined according to their geometrical characteristics and the natural means of discharging smoke is feasible to the large building of saling books. based on analyzing of smoke

    通過對案例分析研究，本文認為大型書城建築性能化防火設計研究的最終目的是保證人員生命安全和保證建築結構安全，在模擬計算和量化分析的基礎上，大型書城的防火分區可以將中庭連通的書城區域劃分為一個區，在書城場地內可以採用防火卷簾進行防火分區劃分;在人員疏散設計中，應盡可能利用書城賣場的空間設計較多的安全出口和增大疏散寬度，其安全出口數量、寬度和疏散距離可以根據人員安全疏散時間和煙氣溫度、沉降高度、 co2濃度、 co濃度、能見度模擬計算結果驗證確定;在防排煙方式的選擇上，應當根據建築物的幾何特點選取最適宜的措施，就大型書城建築而言，採用自然排煙的方式是可行的。

  4. Direct separation of co _ ( 2 ) from flue gas will lead to a reduction of power generation efficiency and an increase of power generation cost. the content of co _ ( 2 ) in flue gas is only about 3 - 15 %, which will lead to complicated separation process and high cost. this is because co _ ( 2 ) separation is very difficult from common flue gas, which has low co _ ( 2 ) concentration and high n _ ( 2 ) concentration at normal pressure

    從鍋爐排煙中分離co _ 2將在一定程度上使電站效率降低，發電成本增加，其主要原因是燃煤電站鍋爐排煙中co _ 2濃度一般僅為3 15 ，在較低的壓力下從以氮氣為主要成分的混合氣體中分離較低濃度的co _ 2氣體的難度很大，從而導致分離設備復雜，成本較高。
  5. It tell us : the abrasive capability of fly ash ; the similar calculation of ash erosion ; the calculation of ash erosion in the tube in turn and tube out of turn ; the reason of tube abrasion for gas flue ; the influence of air parameter for fly ash erosion ; the influence of changing temperature ; the influence of the flue gas composition, etc. next, it advances the solving measure ; reduce the flue gas velocity ; reduce the concentration of fly ash ; responsible construction : replace smooth tube with spiral tube ; use the new material of abrasion ; fuel desulfurization ; reduce so3 of flue gas ; raise flue gas temperature, making it up the dew point ; use the abrasion - resistance material to resist abrasion
