1、 提高管壁温度若不投暖风器,酷游网址酷游网址进口风温在25°C~45°C之间,导致低温段管壁温度下降,烟气侧出现水蒸汽冷凝。酷游网址酷游网址冷端壁温tb与进风温度tpy及排烟温度tca的关系式为:tb=0.5(tca+tpy)-C,管式空预器:C=15°C。当tca=160°C,tpy=45°C时,则tb=87.5℃;壁温低,烟气侧水蒸汽易冷凝。安装有效热风器后,确保低温预热器进口风温>80°C,并能在运行中正常投用,从而提高预热器管壁温度。
1, increase the temperature of the tube wall if not cast heaters, enamel tube air preheater inlet air temperature between 25 C ~ 45 C, resulting in low temperature section of the tube wall temperature decreased, the flue gas side appears the condensation of water vapor. Enamel tube air preheater cold end wall temperature between TB and TPY type inlet air temperature and exhaust temperature of TCA: tb=0.5 (tca+tpy) -C, tube type air pre heater: C=15 C. When the tca=160 C tpy=45 C, is tb=87.5 DEG C; the wall temperature is low, the flue gas side condensation steam easily. Installation of effective air heater, ensuring low temperature preheater inlet temperature >80 degrees C, and can run in normal operation, thereby enhancing the preheater tube wall temperature.
2、减少烟气中水蒸汽分压力为减轻雾化蒸汽对水蒸汽分压力的影响,在运行中严格控制油喷嘴雾化蒸汽的汽耗率0.1kg(汽)/kg(油),并用压缩空气雾化来替代蒸汽雾化,以减少烟气中的水蒸汽分压力。
2, reduce the pressure to reduce the water vapor in flue gas steam atomizing effect on partial pressure of water vapor, strictly control the steam atomizing oil nozzle in the operation of the steam consumption rate of 0.1kg (steam) /kg (oil), and the use of compressed air atomization to replace steam atomizing, in order to reduce the water vapor in the flue gas pressure.
3、选用新材料将低温段酷游网址酷游网址管壁温度提高到超过烟气露点是不容易的,那将会给锅炉带来很大的热损失。所以,要在排烟温度合理的情况下,充分利用烟气余热,就需要采用防止低温腐蚀的新材料。经咨询、查阅及调研,当采用特种搪瓷这种新材料换热时,既有较好的传热效果(对流传热系数K0=24.8W/m2·℃,而钢管对流传热系数K0=24.2W/m2·℃),又有较好的耐腐蚀、耐磨损性能。作为低温酷游网址酷游网址的管材,以适应高硫油。
3, the use of new materials in low temperature section of enamel tube air preheater tube wall temperature increases above the dew point of flue gas is not easy, it will bring great loss to the boiler heat. So, in the exhaust gas temperature and reasonable circumstances, make full use of the waste heat of the flue gas, it is necessary to use new material of prevent low temperature corrosion. The Advisory, consulting and research, when using special enamel this new material of heat exchanger, which has good heat transfer performance (convection heat transfer coefficient K0=24.8W/m2, C, and the steel tube of convection heat transfer coefficient K0=24.2W/m2 C), but also has better corrosion resistance, abrasion resistance. As the low temperature enamel tube air preheater pipe, in order to adapt to the high sulfur oil.
酷游网址酷游网址酷游网址与钢管酷游网址酷游网址相比,主要有三大优点:
Enamel pipe enamel tube air preheater and steel enamel tube air preheater has three major advantages compared to:
(1)耐腐蚀:酷游网址的耐酸度比金属管要高出数百倍。
(1) corrosion: Enamel tube acid resistance than metal pipe should be higher than the hundreds of times.
(2)耐磨损:据有关资料证明,搪瓷釉层的维氏硬度HV=652,而金属Q235A钢的维氏硬度HV=114,可见搪瓷的耐磨性要大大超过金属Q235A钢。
(2) wear: according to relevant information to prove hardness, Vivtorinox HV=652 enamel layer, and the metal of Q235A steel HV=114 Vivtorinox hardness, wear resistance and visible enamel to greatly exceed the metal of Q235A steel.
(3)阻力小、传热好:根据有关资料,酷游网址表面绝对粗糙度为0.005mm,而Q235A钢管表面粗糙度为0.2mm,是酷游网址的40倍。因此,酷游网址表面光洁度高,不易粘灰,烟气流通阻力小,灰污热阻小,传热系数大。
(3) the small resistance, good heat transfer: according to the relevant data, the enamel pipe surface absolute roughness is 0.005mm, and the Q235A steel surface roughness is 0.2mm, is 40 times the enamel pipe. Therefore, the enamel pipe surface smoothness high, is not easy to absorb dust, flue gas flow resistance is small, fouling thermal resistance is small, large heat transfer coefficient.
