300 MW和1000 MW燃煤机组能耗和污染物排放特性
|
摘要
通过试验和技术手段,以供电煤耗率和污染物排放绩效作为燃煤机组节能减排指标,分析了多台燃煤机组负荷率对节能减排指标的影响。研究结果表明,机组供电煤耗率与负荷率具有较好的二次曲线关系,但污染物排放绩效与机组负荷之间不具有明显的规律性,无法建立相对应的模型。大容量高参数机组的污染物排放绩效,明显小于小容量低参数机组的污染物排放绩效。根据研究所得的数据,可为燃煤火电机组与新能源发电机组之间的相互协调及节能调度方案,提供参考。
The effect of load rate of multiple coal-fired power units on energy saving and emission reduction was studied by experiments with net coal consumption rate, pollution emission performance as index of energy saving and emission reduction. The research results indicate that there is a good quadratic curve function between net coal consumption rate and power load, but there is not a good function between pollution emission performance and power load. However, the pollution emission performance of large capacity and high parameter units is better than that of small capacity and low parameter units. The research results could provide reference for coordination and energy-saving dispatching of coal-fired power units and new energy generation.
