本文图线能够帮助操作人员计算出烟道气的估计露点。首先用燃料的氢含量和过量空气值计算燃料烟气中水分的体积百分数(图1),而后用燃料中的硫含量计算露点(图2)。估算水蒸汽含量的图线(图1)是基于化学计算法得出的,该算法遵循下列假定: 1.在炉子和烟道中的气体服从理想气体定律。 2.燃料的燃烧是完全的,碳转化为CO_2。 3.仅仅是燃料中的氢和碳的浓度影响烟 The plot line in this article helps the operator calculate the estimated dew point of the flue gas. The volumetric percentage of moisture in the flue gas is first calculated using the hydrogen content of the fuel and the excess air value (Figure 1), and then the dew point is calculated from the sulfur content of the fuel (Figure 2). The plot for estimating water vapor content (Figure 1) is based on stoichiometry, which follows the assumptions: 1. The gas in the furnace and flue gas obeys the ideal gas law. 2. The combustion of fuel is complete and carbon is converted to CO_2. 3. Only the concentration of hydrogen and carbon in the fuel affects the smoke
