As global energy demand rises, so does the need for efficient power generation. In the foreseeable future, fossil power plants will remain the key source of electric power. Given that these plants emit not just carbon dioxide but other environmentally harmful substances like particulates and oxides of nitrogen and sulfur, innovative emission control technology will become increasingly important worldwide. Siemens has a rich portfolio of solutions capable of reducing these substances in exhaust emissions, efficiently and effectively.
Our flue gas cleaning portfolio includes individually tailored as well as ready-made systems – systems that already conform to the latest and most stringent mercury removal standards. Exceptionally efficient at filtering out mercury, sulfor dioxide, acid gas and particulate matter, they’re used most commonly in coal-fired power plants and in industrial processing facilities. Our electrostatic precipitators, for instance, extract more than 99.9 percent of the dust in coal-fired power plants’ flue gas, and our wet electrostatic precipitators can even remove tiny, hard-to-trap particulates, vapor and mist (including sulfor trioxide acid mist).
Our portfolio additionally includes high-efficiency burner technology for the combustion systems in coal-fired boiler plants. Our low nitrogen oxide burners, as their name implies, produce just small quantities of nitrogen oxides and significantly reduce the pollutants in the actual boiler. Based on technology acquired along with the company Advanced Burner Technologies in 2006, these proven and affordable burners are available as retrofits and upgrades to reduce combustion systems’ NOx output. We’ve successfully retrofitted this technology to an installed base of coal-fired boilers with a total output of around 16,000 megawatts.
In collaboration with Voestalpine, we co-developed and implemented Maximized Emission Reduction Sintering (Meros) technology for the steel industry. Meros is the most advanced and efficient system for cleaning the offgas produced by sintering, one of the steps involved in the production of iron. On average, the Meros process reduces particulate matter, sulfur dioxides, heavy metals and other pollutants in sinter-plant offgas by 90 percent, compared to other current wet cleaning methods.
