EFFECTS OF ENERGY RECOVERY TECHNOLOGY IMPLEMENTATION ON GHG REDUCTION IN INDUSTRIAL WASTE TREATMENT EQUIPMENT: A CASE STUDY OF ROTARY KILN STOKER INCINERATOR

Abstract

 The purpose of this study was to develop a heat balance model of a rotary kiln and stoker furnace, which is often used as an industrial waste incinerator, and to estimate the GHG reduction effect of the energy recovery technologies. A heat balance model was developed that takes into account the heat and exhaust gas characteristics of a rotary kiln-stoker furnace that can accept a variety of industrial wastes, and the presence or absence of a sludge dryer process, which is characteristic of industrial waste reactors, to quantify the GHG reduction effects of two types of energy recovery technologies, depending on the difficulty of installation. As a result, it was found that it is necessary to create a precise heat balance model when introducing binary power generation, and it is more effective to update the boiler that uses saturated steam than superheated steam when updating the waste heat boiler.
