Analog-experiment analysis of ash-deposition monitor ing model of boiler economizers in power plants
Abstract: Ash deposition is a form of particulate fouling, and appears usually in boiler economizers. The ash deposition increases capital expenditure, energy input and maintenance costs. An analog experiment for monitoring ash deposition was performed from the analogous objective of a 410 t/h boiler economizer to verify the rationality and reliability of the ash-deposition-monitoring model presented in order to increase the security and economy in economizer running. The analog experiment platform is a tube-shell exchanger that conforms well to the conditions of a self-modeling area. The analog flue gas in the shellside is the heated air mixed with ash, and in the tube side the fluid is water heated by the flue gas. The fluid state in the water side and the flue gas side follows the second self-modeling area. A 4-factor-3-level orthogonal table was used to schedule 9 operation con

模拟实验分析灰分沉积监察荷兰模型的锅炉省煤器在电厂
摘要：积灰也是另一种形式的颗粒物污染，并似乎在通常锅炉省煤器。灰分沉积增加资本开支，能源的投入和维修费用。一个模拟实验监测积灰表现，从客观类比一个410吨/小时的锅炉省煤器，以核实的合理性和可靠性，灰分沉积监测模型，以增加安全性与经济性，在省煤器运行。模拟实验平台是一个管壳换热器符合良好，进行了为期两个月的自我造型区。模拟烟道气中的壳是热空气混合灰，并在管侧流体是水加热烟气。流体状态，在水一方和烟气侧如下第二个自我造型区。 4因子3水平的正交表是用来附表9操作条件的正交实验中，与4种因素正在热电站，烟气速度，飞灰，粒径及加入灰烬量，而3个层面是不同的价值观念差异，是由于位置班级在每个因素。该积灰热阻的计算方法，模型与测量参数的温度和压力下降。它表明我们的价值观的积灰热阻逐渐上升到一个稳定的国家。与实验结果是可靠的是F检验方法，在α = 01001 。因此，该模型可应用于在线监测积灰在锅炉省煤器在电厂中，并提供科学决策上积灰预测和吹灰。
