目前国内的火力发电机组主要是以燃煤为主,煤炭燃烧会产生大量的二氧化碳、二氧化硫等酸性气体,对于这些气体如果不进行科学处理就排入大气,会造成大气污染,从而进一步加剧当前我国的雾霾情况。为此国家提出要在2020年对燃煤机组全面实施超低排放和节能改造。在下面文章里,我们就对燃煤机组超低排放脱硫方案的选择进行探讨。 At present, domestic thermal power units are mainly coal-based, and coal combustion generates a large amount of acid gases such as carbon dioxide and sulfur dioxide. If these gases are discharged into the atmosphere without scientific treatment, they will cause air pollution and further aggravate the current situation in our country The haze situation. To this end the country proposed to fully implement ultra-low emissions and energy-saving renovation of coal-fired generating units by 2020. In the following article, we discuss the options for desulfurization of ultra-low emissions coal-fired units.
