Effect of Cooling Cleaning System on the Performance and Emission Characteristics of Producer Gas Operated Dual-Fuel CI Engine

摘要

The performance and emission characteristics of liquid fuel-producer gas operated dual fuel engine depend on the quality of PG as tar content and temperature. In the present work cooling cleaning system has been used with the gasifier-engine system to reduce the tar content and cool the producer gas before inducting into the combustion chamber of the CI engine. The experiments were conducted on 5.2 kW, DI, 4 stroke, CI engine operated at 1500 rpm. It has been observed, improved performance and reduced emission levels for the CI engine dual-fuel operation with the use of cooling cleaning system. Experimental results showed that the temperature of the PG after the cooling cleaning system was reduced to 31°C-34°C which is a requirement for the CI engine operation for the diesel/HOME-PG dual-fuel engine operation and tar content of PG was reduced from 320mg/Nm~3 to about 55mg/Nm~3 entering to the engine. Also, the emission levels were reduced, such as smoke 7%-8.5% compared to the wet filter provided with the gasifier-engine system.
