A Novel Hybrid Design of Incineration-Gasification for Energy Saving

Abstract:

Nowadays, Municipal Solid Waste (MSW) becomes a crucial problem worldwide where it is created the impact to environment, social as well as health. The non-sanitary landfill is widespread used for waste disposal in the rural area because of its low investment and operation cost. However, it has negative effect on human health and environment. Thermal treatment of MSW by incineration is considered as an option for effective treatment technique due to the fast reduction in mass and volume of MSW. However, with high moisture content in MSW, it is necessary to use auxiliary fuel in order to maintain the high temperature of combustion process and led to the high operating cost, especially for the small scale incinerator without energy recovery. A novel hybrid incineration-gasification can be used in order to overcome this drawback by using a downdraft gasifier with Refuse Derived Fuel (RDF) as feedstock to generate the syngas which can be substituted the auxiliary fuel. Hence, this study emphasizes on the development of a novel hybrid incineration-gasification as a cleaner technology to get rid of MSW generated with a destruction capacity of 30 ton per day (TPD). The novel system comprises of a controlled-air incinerator with two combustion chambers, automatic feeding machine and wet scrubber. A 100 kg/hr downdraft gasifier has aim to use RDF from dry fraction of MSW as feedstock to produce syngas to substitute the auxiliary fuel used in the secondary burner of the incinerator in order to maintain the desire its temperature. This cleaner and novel hybrid technology can implement to get rid of MSW properly for energy saving and sustainable development.
