摘要
在湿法烟气脱硫系统中,是否设置GGH(烟气换热器),对脱硫工程的投资和经济运行有较大影响。对氮氧化物NOx落地浓度也有重要影响。结合实际2×300 MW机组,对设置与不设置GGH的技术经济性及对环境的影响进行了分析,为有关部门制定相关策略提供了参考。
In the wet flue gas desulfurization system, whether or not GGH （gas-gas heater） is included has great influence on the investment and operation cost. It also has effect on the ground concentration of NOx. Combining desulfurization program of real 2 × 300 MW units, the technology, economy and its environmental impact are analyzed.
