Study of Domestic SRF Quality Changes Depending on the Changes in SRF Regulations and Raw Materials

Abstract

The goal of domestic SRF (Solid Refuse Fuel) regulation changes, which have been mitigated-, is to make the increased use of combustible waste. SRF’s standard (LHV; Low Heating Value) has been changed in from 6,000 kcal/kg to 3,500 kcal/kg. Fluff type SRF, which is made of the simple shredded waste in plant or construction sites, have been recognized as SRF. The SRF’s qualities such as calorific value, ash content, and chloride content, were more degraded than the changes before. Low LHV SRFs (below 6,000 kcal/kg)- increased by 12%. SRFs with a low ash content (below 5 wt. %) decreased by 13%. Good grade SRFs with a chlorine content below 0.5 wt. % decreased. In addition, the SRFs originating from sorted household waste had good qualities, compared to SRFs from industrial waste.
