          冷凝器對天然氣熱風爐的運行帶來哪些效果

          文章出處:   發布時間:2019-08-29 13:26:57   瀏覽:29

          天然氣熱風爐是以天然氣感化動力的,是以熱風爐的應用范圍也是如斯。相較于傳統的燃煤熱風爐來講,燃氣熱風爐有了很大的轉變,比如說冷凝器的設置裝備擺設,它能對燃氣熱風爐的運轉后果帶來哪些影響呢?事實證明,將燃氣熱風爐與冷凝器一路共同應用的話,對節儉天然氣用量有很大的利益。煙氣冷凝余熱收受接管裝配應用溫度較低的水或氛圍冷卻煙氣,完成煙氣溫度低落;使得接近換熱面地區煙氣中水蒸汽冷凝,同時完成煙氣顯熱開釋和水蒸汽固結潛熱開釋。
          Natural gas hot-blast stove is driven by natural gas sensitization, so is the application scope of hot-blast stove. Compared with the traditional coal-fired hot-blast stove, the gas-fired hot-blast stove has undergone a great change. For example, the installation of condenser equipment, what impact can it have on the operation consequences of the gas-fired hot-blast stove? Facts have proved that it is of great benefit to save the consumption of natural gas if the gas hot blast stove and the condenser are used together. The flue gas condensation waste heat receiving and receiving pipe assembly uses water or atmosphere with lower temperature to cool the flue gas, so that the temperature of the flue gas is low, so that the water vapor in the flue gas near the heat exchange surface can be condensated, and the sensible heat release of the flue gas and the latent heat release of the water vapor consolidation can be completed at the same time. 與此同時,燃氣熱風爐換熱器內的水或氛圍吸熱而被加熱,完成熱能收受接管,進步熱風爐熱效率。只是簡略的加設了一臺冷凝器,卻能在進步熱效率的同時有用的削減了天然氣的耗費,一石二鳥。
          At the same time, the water or atmosphere in the heat exchanger of gas-fired hot stove is heated to receive heat energy and improve the thermal efficiency of hot stove. A condenser is simply added, but it can improve thermal efficiency while effectively reducing the consumption of natural gas, killing two birds with one stone.

          以燃氣熱風爐適量氛圍系數1.3為例,發生煙氣約莫16.6KG,假如它的煙氣溫度從200℃低落至70℃,放出物理顯熱約1600KJ,水蒸汽冷凝率為50%的話,放出汽化潛熱約1850KJ。
          Taking the appropriate atmosphere coefficient 1.3 of gas hot stove as an example, about 16.6 KG of flue gas occurs. If the temperature of flue gas drops from 200 C to 70 C, about 1600 KJ of physical sensible heat is emitted, and the condensation rate of water vapor is 50%, 1850 KJ of latent heat of vaporization is emitted.

          假如這其中有80%煙氣進入熱能收受接管裝配,那末就能夠進步熱能應用率8%以上,節儉天然氣燃料近10%,這個數據對付燃氣熱風爐來講是異常可觀的。
          If 80% of the flue gas enters the thermal energy receiving and receiving tube assembly, the thermal energy utilization rate can be improved by more than 8% and the natural gas fuel can be saved by nearly 10%. This data is remarkable for gas hot blast stoves.

          綜合上述闡發可知,燃氣熱風爐采用的是分體安排,裝置形式多樣,機動靠得住;而且以螺旋鰭片管作為熱面,換熱效率高,受熱面充分,煙氣側體系阻力小,能夠滿意應用請求。
          From the above explanations, it can be seen that the gas hot blast stove is arranged separately, with various devices and reliable maneuverability; moreover, the spiral finned tube is used as the hot surface, which has high heat transfer efficiency, sufficient heating surface, low resistance of the flue gas side system and can satisfy the application requirements.
