convection tube造句
例句與造句
- Abstract : the in servie tubular heaters built early in refineries and chemical plans have low thermal load and low heat efficiency , therefore measures for technical reform are offered , including ( 1 ) enlarging the surface area of convection tubes to increase the thermal load of rhe convection section ; ( 2 ) increasign the heat interchanging area of radiant tubes ; ( 3 ) changing the height of the chimney ; ( 4 ) using new burner with forced air supply to increase calorific capacityu ; ( 5 ) adding air preheater between the convection section and chimney to enhence the temperature of the air entering the furnace ; ( 6 ) adopting high temperature radiant coating to improve the effect of radiant heat interchanging
文摘:針對早期建造的煉油廠和化工廠在役管式加熱爐熱負(fù)荷和熱效率低的狀況,提出了若干技術(shù)改造措施包括,增大對流管表面積以增大對流段的熱負(fù)荷;增加輻射管的換熱面積;修正煙囪高度;換用新型燃燒器,變自然通風(fēng)為強(qiáng)制供風(fēng),以增大燃燒器的發(fā)熱量,減小過??諝庀禂?shù),節(jié)省燃料2 % 3 % ;在對流段和煙囪之間增設(shè)空氣預(yù)熱器以提高空氣入爐溫度;采用高溫輻射涂料增強(qiáng)輻射換熱效果,從而增加熱源對爐壁的輻射傳熱量和爐管的傳熱量等。 - The in servie tubular heaters built early in refineries and chemical plans have low thermal load and low heat efficiency , therefore measures for technical reform are offered , including ( 1 ) enlarging the surface area of convection tubes to increase the thermal load of rhe convection section ; ( 2 ) increasign the heat interchanging area of radiant tubes ; ( 3 ) changing the height of the chimney ; ( 4 ) using new burner with forced air supply to increase calorific capacityu ; ( 5 ) adding air preheater between the convection section and chimney to enhence the temperature of the air entering the furnace ; ( 6 ) adopting high temperature radiant coating to improve the effect of radiant heat interchanging
