Title:Thermal Treatment of Sewage Sludge – Co-Incineration in Power Plants
Publication date:06 2014
Price:52.00 €
Thermal treatment of sewage sludge is in regard to quantity the most important disposal route in Germany. It is an important option for a safe, economically efficient and environmentally sound sludge disposal. Since the late 1980ies, the percentage of sludges which are treated thermally has risen from about 12 % to more than 50 %. Especially co-incineration of sludges in coal power plants has increased strongly over the last years. About 25 % of all sewage sludges produced in Germany are disposed of using co-incineration in coal power plants. Thus the share of co-incineration in overall sludge disposal is about the same as that of mono-incineration. Mono-incineration is discussed in detail in the Advisory Guideline DWA-M 386 “Thermal Treatment of Sewage Sludge – Mono-Incineration”. The objective of the Advisory Guideline DWA-M 387 is to give fundamental information for the technical realisation and operation of plants for the co-incineration of sewage sludges in coal power plants. Based on fuel characteristics of sewage sludge, the effects of co-incineration on various firing systems for brown and black coal, on flue gas purification and on incineration residues are dealt with in detail. Furthermore, information on legal framework and economic efficiency is presented. Finally, several practical examples of co-incineration plants are discussed. For planners and operators of co-incineration plants, this Advisory Guideline shall supply a basis for the determination about concepts during the planning phase and for decisions on investments for the construction of new plants. This Advisory Guideline also supplies important information for machinery manufacturers and plant engineers. However, it does not give detailed dimensioning standards for a process engineering layout of the plant or parts of it.
