“…Several previous studies have investigated several ways to reduce the risk of waste for cofiring fuel. The addition of aluminum-based additives shows a reduction in the risk of slagging-fouling because it can increase the Al2O3 content in the ash [33]. In reducing the risk of corrosion, Wu et al suggested that burning SRF with coal and adding kaolinite additives.…”

“…In general, this value is higher than the RDF ash content of household waste and agricultural waste. The ash content in the RDF of household waste is dominated by CaO (19.03%), Fe2O3 (3.01%), K2O (2.58%), and Na2O (5.58%) while the RDF of agricultural waste is CaO (7.92%), Fe2O3 (5.04%), K2O (27.71%), and Na2O (3.44%) [33] [34]. RDF-R also has a high chlorine content of 2879 ppm which may influences the corrosion occurrence on boiler walls or heat exchanger pipes [19].…”

Environmental pollution, especially in rivers, increases every year, especially due to waste being dumped directly into rivers. Municipal solid waste can be processed into refused derived fuel to be used as a coal fuel mixture in CFPP. This research aims to analyse the risk of burning RDF originating from river waste as a single fuel and RDF as a mixed fuel for coal up to 30%. Solid fuel standard tests were used to determine sample characteristics and properties. To determine the initial risk of the ash deposition problem of RDF from river waste (RDF-R), the theoretical prediction indices are used. As a single fuel, RDF-R exhibits a high risk of slagging due to its high composition of Fe2O3 and CaO in the ash. Adding RDF-R to coal leads to increase of the slagging and fouling risk. However, addition up to 30% RDF-R to coal has insignificant effect in corrosion because the sulfur content in the coal can reduce the corrosive effects of chlorine.
