纏管式換熱器運用效果與節能狀況

1. Less weight of equipment: compact design and higher efficiency of heat transfer, save more materials comparing to traditional exchangers.

     材料節省: 纏繞管式換熱器結構緊湊、單位容積的傳熱面積高,與其它換熱器相比,材料節省明顯。

2. Better energy recovery: better heat transfer efficiency, lower workload of firing heater, lower inlet tempaturer to air cooler, recovers more energy by 20 % or more.

     節能:換熱器效率高,加熱爐負荷低、進空冷時物料的溫度低,系統能耗降低了1/5。

3. Optimized process and lower cost: spiral-tube heat exchangers has higher efficiency, compact in size, and reduced hot/cold approaches

     系統優化、降低投資:高效緊湊的纏繞管式換熱器,實現小端差換熱:

     No need for reactor heater or use start-up heater only

     取消反應加熱爐或改用開工加熱爐

     Reduced inlet temperature requires less high pressure air cooling

     降低進高壓空冷器的入口溫度減少空冷器數量

     Reduced reactor system pressure difference (ΔP)

    反應系統壓降降低

4. As a high efficient heat exchanger, single spiral-tube heat exchanger can serve most of applications which need two or more traditional exchangers. Hence, the installation and piping cost can be   

    reduced remarkably.

    纏繞管式換熱器作為高效緊湊型換熱設備,在相同條件下,與常規換熱器相比,設備數量減少、占地空間小,方便安裝,高壓法蘭、管道等配管工作量小

5. No specific requirement for pressure and temperature, either at start-up or normal operation, it works highly reliable against the process upsets.

    不同介質之間壓差和溫差的高低,包括開停車時升降溫的速率,均沒有限制,且不受工況波動的影響。
