【摘要】：火电机组超低排放改造有效降低了燃煤电厂的污染物排放总量,但部分改造后的脱硫系统在运行中暴露出设计裕量过大、改造过度、运行能耗过高等问题。对此本文提出:应合理确定脱硫系统设计边界条件,根据实际燃煤及煤源选择合适的设计煤质硫分;优化脱硫系统设计方案,选择节能设备,设计方案应兼顾不同负荷工况下脱硫系统的灵活调节与节能运行;调整运行方式、优化运行参数,并使用脱硫增效剂等。上述措施可为同类工程设计优化提供参考。
[Abstract]:The retrofit of ultra-low emission of thermal power units effectively reduces the total pollutant emission of coal-fired power plants, but some of the retrofitted desulphurization systems expose excessive design margin and excessive retrofit in operation. The paper points out that the design boundary condition of desulfurization system should be reasonably determined, the suitable design coal quality sulfur should be selected according to the actual coal combustion and coal source, the design scheme of desulfurization system should be optimized, and the energy saving equipment should be selected. The design scheme should take into account the flexible regulation and energy-saving operation of the desulfurization system under different load conditions, adjust the operation mode, optimize the operation parameters, and use desulfurization synergist, etc. The above measures can provide a reference for the design optimization of similar projects.
