有证据表明，北美东部湿硫酸盐沉积率在一年的夏季比冬季高，因此建议对排放进行季节性控制，作为尽量减少酸沉积控制成本的一种手段。本文对4 ~ 9月电厂以天然气代煤、以油代油的建议进行了评价。提出了一个模型，模拟在东部31个州地区的发电厂的煤炭和石油的天然气替代，以减少沉积在阿迪朗达克受体的总成本最小化。该模型的结果表明：1）季节性控制与全年控制的有效性增加; 2）燃料消耗水平的变化，作为替代的结果;和3）在阿迪朗达克受体实现不同程度的沉积减少的成本。季节性天然气替代的成本相比，其他拟议的控制方法的成本估计。结论是，季节性天然气替代与其他控制方法相比具有成本竞争力，至少在某些工厂和州是如此。
Based on evidence that the rate of wet sulfate deposition in eastern North America is higher in the summer half of the year than in the winter half, seasonal control of emissions is proposed as a means of minimizing acid deposition control costs. This paper evaluates the proposal that natural gas be substituted for coal and oil in electric power plants during April through September. A model is presented that simulates the substitution of natural gas for coal and oil in power plants in the eastern 31 state region, so as to minimize total costs with respect to deposition reductions at an Adirondack receptor. The results of the model show: 1) the increased effectiveness of seasonal versus year-round controls; 2) changes in fuel consumption levels as a result of substitution; and 3) the costs of achieving various levels of deposition reduction at an Adirondack receptor. The costs of seasonal gas substitution are compared to cost estimates for other proposed control methods. The conclusion is that seasonal gas substitution is cost-competitive with other control methods, at least in some plants and states.
