12 Heater stack emissions NOx 加热炉烟囱排放：NOx
Thermal NOX 热产生的NOx Primarily function of flamme temperature 主要源于燃烧温度的作用 Estimate : 3 tons per year (tpa) / process MW 估算的排放量： 工艺流程中每MW每年可产生3吨 Fuel NOX 燃料产生的NOx Depends on Nitrogen in fuel (N% wt.) 取决于燃料中氮的量（N重量百分比） Emission = 36*N tpa / process MW 排放量= 工艺流程中每MW每年可产生36x氮的重量百分比 Estimate : N = 0,25% 9 tpa / MW 估计：氮的重量百分比N = 0.25%, 则排放量为：每MW每年9吨 Total NOX = Thermal + Fuel NOX 总的NOx排放量=热产生的NOx+燃料产生的NOx Estimate = 12 tpa / MW 估计： 总的NOx排放量=12吨每年每MW Valuation = 1000 USD / ton  $12,000 / MW / year 估价 = 1000 美元/每吨  相当于每年每MW 1万2千美元。 Hydrocarbon China Beijing April 2006
