Experimental investigation of emission and noise characteristics of a dual fuel with cotton stalk

Energy demand throughout the world is rapidly increasing and to fulfill that demand, a large amount of fossil fuels is used in majority of the power generation systems. High use of the fossil fuels causes massive environmental pollution and GHG. These issues can be addressed to a great extent by using biomass materials as a substitute to the fossil fuels. The biomass materials require certain systems, to ensure high conversion efficiency into thermal and electrical energy; one of such systems is the biomass gasifier. In this study a downdraft gasifier is coupled with a dual fuel engine. When the producer gas is blended with diesel in a dual fuel engine high amount of nitrogen is present in the producer gas, but the temperature of the combustion chamber is low so nitrogen behaves like an inert gas and because of this 67.8% NOx emission is reduced. A reduction of 60% in GHG emission is observed. The noise level is increased slightly. (C) 2019 Elsevier Ltd. All rights reserved.
