Abstract : apply computer simulation to the distribution pattern of air - flow without considering the cold condition of the combustion and compare the flow patterns under different designed circumstances. and the effect of the design of the partition in the air way of the burner on the flow and mixture of gas and air is especially studied. the result shows that the design of partition plays a very important role in strengthening the mixture of gas and air, but increases the loss of the resistance in the air way and the total pressure of the air way in same working conditions needs increasing
文摘:應用計算機模擬的方法,在不考慮燃燒的冷態情況下,研究了熱風爐燃燒室內的氣流分佈規律.在此基礎上,比較了2種不同設計方案的氣流流動特徵,尤其是研究了燃燒器空氣通道內阻流板的設置與否對空氣和煤氣的流動和混合的影響.結果表明,阻流板的設計對加強空氣和煤氣的混合有著極為重要的作用,同時也增加了空氣管道的阻力損失,在同樣的工況條件下需要提高管道系統的總壓力Energy consumption of heating rooms will increase when air exchange rate become large. because the mechanisms of heating methods used currently, such as radiator heating, ceiling heating and warm - air heating, are different from each - other, the indoor thermal environment is not the same when each one of them employed for room heating. for enhancing energy efficiency of heating rooms, indoor thermal comfort and energy saving effects should be investigated when natural ventilation is used to make a good air quality indoors
房間換氣次數的增加勢必導致供暖房間能耗加大,頂棚輻射、散熱器和熱風等三種採暖方式由於供暖機理不同,形成的室內熱環境特徵不同,通風換氣時產生的通風熱損失也有所區別,為了提高大換氣量房間的供暖節能效果,必須對不同供暖方式在大換氣量情況下的熱舒適性與節能效應進行研究。Meteorological disaster ( mainly wind damagae, waterlog disaster and drought damage ) was classified by five categories as slight, not serious, medium, relatively serious and serious by the degree of its influence on guangzhou, and divided into 3 ranges in time : short - term ( 2000 2002 ), medium - term ( 2003 2006 ), and long - term ( 2007 2010 ). through the investigation by 57 experts who had been engaged in disatser research for a long time, with application expert of assessment method ( delphi method ) the results showed that wind damage would have the greatest influence on guangzhou among the meteorological disasters. in the coming 10 years, there would be tropical cyclone influence on guangzhou almost every year, which would bring a certain extent of damage that was 10 15 % more serious than that in normal year. waterlog disaster brings less influence compared them with tropical cyclone in short term, but its influence was close to that of tropical cyclone in mid - term and even surpasses that of tropical cyclone in long - term. waterlog damage in forcasting period will be about 10 % more serious than that in normal year
將氣象災害(主要是風災、澇災和旱災)對廣州市的影響程度分成輕微、偏輕、中等、偏重和嚴重五個級別,在時間上將未來10年分成三個時期:近期( 2000 2002年) 、中期( 2003 2006年) 、遠期( 2007 2010年) ,通過對廣州市57名長期從事災害研究的專家的調查,再運用專家評估法,結果表明:在三種災害中,對廣州市影響最大的是風災,未來10年幾乎每年都有熱帶氣旋影響廣州,造成較大程度的損失,其損失程度約比中等年份偏多10 15 ;澇災對廣州市的影響在近期比臺風小,中期與臺風的影響接近,至遠期的影響超過臺風,整個預測期內比中等年份偏多10左右。It is found that the climatological mean of wind speed and air - sea humidity difference are both large, the variation of wind speed are almost in phase with air - sea humidity difference, yielding much larger or smaller latent heat flux. so the ocean release the most latent heat in its own winter of the two hemispheres when both wind speed and air - sea humidity difference are large
發現在南北兩信風區,風速和海氣濕度差的變化幾乎是同位相的,平均背景風速和海氣濕度差都較大,他們互相加強彼此對潛熱通量變化的貢獻,所以海洋潛熱損失最大是發生信風南北兩區的各自風速和海氣濕度差都較大的冬季。Via the analysis of heat balance computation model and the computation of online heat balance for industrial coal boiler, this dissertation researched overall input heat, efficient utilized quantity of heat, heat losing of discharge flue gas, heat losing of chemistry and mechanism incomplete combustion, heat losing of dispelling heat of boiler, heat efficiency, air superfluous coefficient, wind speed, wind quantity, computation of primary air circle cutting and whose influence on boiler combustion efficiency
本文通過對工業煤粉鍋爐熱平衡計算模型的分析,利用在線熱平衡計算,研究了總輸入熱、有效利用熱量、排煙熱損失、化學不完全燃燒熱損失、機械不完全燃燒熱損失、鍋爐散熱熱損失、熱效率、空氣過剩系數、風速、風量及一次風切圓計算以及這些因素對鍋爐燃燒效率的影響。The insulation and the thermal mass, coupled with the gains from the conservatory and the buffering effect of the earth sheltering provide comfortable conditions
一個熱交換通風系統利用高效的12伏直流電扇來保證通往每個房間的氣流,而近可能地減少其熱量損失。In climatological itcz, the mean air - sea humidity difference is greater relatively so that the variation of wind speed under large mean air - sea humidity difference is the main factor influencing the variation of latent heat flux. the latent heat loss is greatest from june to august when the wind speed is largest in the region
在氣候平均的工tcz區,平均的背景海氣濕度差比較大,所以平均海氣濕度差背景下風速的變化主導潛熱通量的變化,因此該區潛熱損失最大值發生在風速最大的6一8月份。分享友人
