Abstract

The necessity to implement advanced combustion technologies to utilize MSW/SRF/RDF and coal reject waste is an important problem for Ukraine to be solved. The introduction of such technologies will favor to involve annually about 2 mln t of RDF and partly cover deficit of bituminous coal, lack of which is currently faced. The technological niche for CFB combustion of RDF/SRF has certain optimal range bearing in mind technological, ecological (2010/75/EU Directive etc.) and financial performance. In view of this it seems reasonable to implement CFB for RDF/SRF firing starting from boiler steam capacity of 50-75 t/h while stoker firing of RDF could be efficiently implemented for lower range. The design of such boiler should rely upon lessons learned of commissioning and operating large-scale CFB boiler (having steam capacity of 670 t/h; 545/545 C) we obtained at Starobeshevo Power Plant in Ukraine. Accounting for the above the analysis of implementation and modifications made at large-scale CFB boiler (cyclones, seal pot, fluidized bed heat exchangers) has been done. The experience was used to design (along with KB “Energomashproekt”) medium-scale CFB boiler (having steam capacity of 75 t/h; 500 C) to burn high ash coal washering wastes and RDF/SRF. The sketch-3D-design of such boiler is presented with key performance. Bibl. 6, Fig. 4, Tab. 4.
