Abstract

Abstract

The effect of moisture content (MC) and additives on the physicochemical properties of RDF was studied by optimizing the preparation of refuse derived fuel (RDF) from hydrolysis residues of organic waste after bio-drying. The experiment set different gradients of MC and additives using bio-drying treated hydrolysis residues from typical organic wastes such as fruits and vegetables, kitchen and garden. The comparison of the compressive strength, expansion rate, forming rate and calorific value showed that the formability of RDF with MC of 25% would be the best, whose compressive strength was 8.28 MPa and expansion rate was 40.41%; while the shaping rate with MC of 30% could be 99.47%. Therefore, the preparation of RDF in MC range of 25%~30% would be better. When MC was 10%, LHV could be 15.98 MJ/kg, which met the level 3 of the Solid Recovered Fuels-Specifications and Classes. Addition of 5% Na₂SiO₃ powder in the preparation of RDF could effectively improve its formability, and ash content could be controlled at about 8.55%, meeting the requirements of the storage, transportation and combustion of RDF.
