煙道受熱面 的英文怎麼說
中文拼音 [yāndàoshòurèmiàn]
煙道受熱面
英文
flue heating surface-
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。For long - term protection of heated pipelines, exhaust pipes, smoke stacks and other heated surfaces up to 550 - 600
長期保護加熱管道、排氣管道、煙囪及其它溫度可高達550 - 600的受熱面。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。
