Abstract
Municipal solid waste (MSW) and charcoal can be used as a substitute fuel in a gas engine. In this work, performance of a downdraft gasifier and gas engine system operated on MSW briquette fuel was investigated. Experimental test was carried out on a 62 kW, four-cylinder, naturally aspirated engine coupled to a 20 kW dynamometer. The downdraft gasifier was used to generate producer gas from MSW briquettes and charcoal. The engine load was varied between 1.5-9.0 kW. Biomass consumption, producer gas production, cold gas efficiency, thermal efficiency of the gas engine, carbon monoxide (CO), hydrocarbon (HC) emissions and exhaust temperature were evaluated. The MSW briquette fuelled operation was compared against that with charcoal. It was found that, the use of MSW briquette led to lowering performance of the downdraft gasifier and gas engine system, in comparison with the use of charcoal. Maximum cold gas and thermal efficiencies obtained were 64.6% and 16% at 4.5 kW and 9 kW loading, respectively. The CO and HC emissions of the gas engine operated on MSW briquettes were higher than that on charcoal, while the exhaust temperatures were similar. ©2019. CBIORE-IJRED. All rights reserved
Highlights
Management of municipal solid waste (MSW) or other solid wastes is one of the major challenges for Thailand (Tippayawong and Tippayawong, 2017)
It consisted of a gasification reactor and a spark ignited engine adapted to operate on producer gas from MSW gasification
Consumption of both biomass feedstocks was increased with increasing engine load
Summary
Management of municipal solid waste (MSW) or other solid wastes is one of the major challenges for Thailand (Tippayawong and Tippayawong, 2017). The reduction technology adopted to reduce MSW are direct burning and briquette fuel production. The burning of MSW focuses on reducing the volume of waste and that can be buried or stored, while the briquetting or densification method focuses on production of alternative fuels to replace fossil fuels in factories (Tippayawong et al, 2018; Piboon et al, 2017; Wongsiriamnuay and Tippayawong, 2015). The use of briquette fuel to generate the producer gas and operate on gas engines for electricity production is very attractive. This approach can help reduce imported energy from overseas
