煙道加熱器
英文
flue heater-
Firstly, simulate flow field of rear smoke channel, plot velocity magnitude and ash concentration distribution in section of entry of heat pipe air preheater, compare with data which were measured in guiyang power station, verify simulation to be reasonable and right. secondly, simulate all kinds of factors which affect flow field ' s uniformity such as length, thickness, location of diffluent board, ash concentration, ash diameter, and so on, find the chiefly factors. thirdly, install guide board in curve channel in rear smoke channel, then simulate its " flow field, plot velocity magnitude and ash concentration distribution
在此基礎上模擬在冬夏兩季不同情況下,不同流速對熱管空氣預熱器壁面溫度的影響;然後對影響整個流場分佈的各種因素:包括分流板長度、厚度、偏離中心流道位置的偏離度、飛灰濃度、飛灰粒徑等因素進行數值模擬;最後提出在分流煙道轉彎處加裝導流板,並模擬加裝導流板后的流場分佈,得到下級空氣預熱器出口、熱管空氣預熱器進口處的斷面速度場分佈、濃度場分佈,以論證加裝導流板能達到流場均勻化的作用。The unique blade louver damper with heared sear air is the solution to large crosssection / high temperature damper applications such as air heater isolation, fgd systems
帶加熱密封空氣的單層葉片百葉窗式檔板門,可用於大截面煙道檔板門和高溫檔板門.例如:空氣加熱器的隔絕門,煙氣脫硫系統中3. on boiler retrofit, the calculation of fuel burning, the heat calculation of boiler inside structure and convection section, and the design of structure parameter of feed water heat exchanger are made. the flue gas channels " resistance calculation and the boiler strength verifying are also carried out. replacement of water cooling wall improves heat exchanging and decreases loss of heat radiant
對鍋爐本體進行了燃料燃燒計算、爐膛結構熱力計算、對流受熱面結構熱力計算、鍋爐給水加熱器結構參數設計、煙道阻力計算及鍋爐元件強度校核等;改進了水冷壁布置使換熱效果更好,減少輻射換熱損失;改進對流段結構,更充分的利用爐膛出口煙氣余熱,提高熱效率;並且進行了煙氣阻力計算、熱效率計算和能量平衡測試,對改進后的稠油燃料和改進前進行了對比,燃燒狀況和熱效率有明顯改善。Independent gas - fired convection heaters incorporating a fan to assist transportation of combustion air and or flue gases
用排氣扇輔助輸送燃燒空氣和或煙道煤氣的獨立式混合燃氣對流加熱器Specification for dedicated liquefied petroleum gas appliances - domestic flueless space heaters including diffusive catalytic combustion heaters ; german version en 449 : 2002
專用液化石油氣裝置規范.家用無煙道房間加熱器There will appear a very uneven flow field, and appear a very big velocity magnitude distribution and ash concentration distribution near back wall. thus, the velocity magnitude is far bigger than that of optimal design velocity magnitude, which will lead to serious wear and tear in metal face of heater. especially, because of curve structure in front of heat pipe air preheater, there is more serious wear and tear
由於靠近豎井后墻面的煙氣流速很大,飛灰濃度也較大,斷面速度分佈的最大速度大於最佳設計速度的2 - 3倍,這樣將造成受熱面的嚴重磨損,特別是熱管空氣預熱器前端煙道的幾何結構有一定的轉角,更增加了磨損的程度。Specification for dedicated liquefied petroleum gas appliances - flueless non - domestic space heaters not exceeding 10 kw
