Abstract

In line with the then emerging air pollution control regulations Union Electric installed a limestone injection wet scrubber sulfur dioxide removal system on an intermediate size coal-fired utility boiler at its Meramec Power Plant on an experimental basis in September, 1968. Approximately 3 years of operation many difficulties were encountered with plugging and scaling of various system components by calcium sulphate. As a result of this experience along with related experiences by other utilities employing similar systems, the experiment was terminated in June, 1971. As a result of the experiences gained, however, second generation experiments in sulfur dioxide removal have been initiated elsewhere with the hope of improved performance. A number of experimental projects are still under tests. Costs in resources, reliability, and disposal of residual by-products are matters of great concern. The ture cost of sulfur dioxide removal systems in dollars and resources is not well known and perhaps a reevaluation of current and future SO2 removal projects is in order at this time before additional resources are committed.

联合电气Meramec工厂二氧化硫脱除系统的历史。

1968年9月，为了符合当时新兴的空气污染控制法规，联合电力公司在其Meramec发电厂的中型燃煤公用事业锅炉上安装了石灰石喷射湿式洗涤器二氧化硫去除系统，作为实验基础。在大约3年的运行中，遇到了许多困难，如硫酸钙堵塞和结垢等。由于这一经验以及其他采用类似系统的公用事业公司的相关经验，该实验于1971年6月终止。然而，由于取得了经验，在其他地方已经开始了第二代二氧化硫去除实验，希望能提高性能。一些实验性项目仍在测试中。资源成本、可靠性和残余副产品的处理是非常值得关注的问题。二氧化硫去除系统在资金和资源方面的实际成本尚不清楚，也许在投入额外资源之前，应该对当前和未来的二氧化硫去除项目进行重新评估。
