摘要
目前国内火力发电厂常见以湿法脱硫为主,此方法是造成白色烟羽现象的主要因素。白色烟羽的源头是水分,烟气中饱和水蒸气是吸热产生的,含有大量潜热,因此,烟气消白的关键就是排放烟气的温度、湿度控制。本文主要对燃煤电厂白色烟羽治理的几种工艺路线进行介绍。
At present, wet desulfurization is the main method in domestic thermal power plants, which is the main cause of white plume. The source of white plume is moisture. The saturated water vapor in flue gas is endothermic and contains a lot of latent heat. Therefore, the key to whitening flue gas is to control the temperature and humidity of flue gas. This paper mainly introduces several process routes of white plume treatment in coal-fired power plants.
