Abstract

The performance and emission characteristics of liquid fuel-producer gas operated dual-fuel engine depend on the quality of producer gas (PG) as tar content and temperature. In the present work cooling cleaning system has been adopted for the gasifier-engine system to reduce the tar content and cool the PG before inducting into the combustion chamber of the diesel engine. The experiments were conducted on 5.2 kW, DI, 4 strokes, diesel engine operated at 1500 rpm. It has been observed, improved performance and reduced emission levels for the dual-fuel operation of the engine with the use of cooling cleaning system. Experimental results showed that the brake thermal efficiency increased by 2-12% for the diesel/HOME-PG dual-fuel engine operation and tar content of PG was reduced from 320mg/Nm3 to about 55mg/Nm3 entering to the engine. Also, the emission levels were reduced, such as hydrocarbon 11.1%-19% and carbon monoxide 10.5%-20% compared to the wet filter provided with the gasifier-engine system. However, NOx emission levels were increased by 8% because of higher temperature due to the combustion of improved quality of PG. The temperature of the PG after the cooling cleaning system was reduced to 310C-340C which is the requirement for the diesel engine operation.
