Co-incineration of sewage sludge in coal fired power plants.Because of the growth of population and industrial applications more and more waste water will be produced. That leads to a increasing appearance of sewage sludge in the future. At the same time the available space on dump sites for land filling the sewage sludge will decrease. The usage of sewage sludge in agriculture as fertilizer is controversial because besides over-fertilisation heavy metal accumulation in soil will take place. The most prosperous way of dealing with dewatered sewage sludge in the future is the co-incineration for exaple in coal fired power plants. Putzmeister as a system supplier has developed a solution for co-incineration of mechanically dewatered sewage sludge in coal fired power plants. System advantages: -Technically secured handling method, approved power plant technique with flue gas cleaning can be used. -Organic compounds in the sewage sludge like, dioxin and furan will be completely destroyed by being incinerated at more than 1000°C -Also the mineral fraction of the sewage sludge can be utilized together with the coal ash in the construction industry. -Cost economic option compared with co-incineration of sewage sludge in household waste incineration plants and with pure sewage sludge incineration plants.
