摘要

Coal based thermal power plant expels pollutants consisting hazardous gases that result in to degradation of ecosystem.On the contrary,gasification technologies offer the potential for clean and efficient energy.At optimum gasifier pressure of 2 bar and steam-fuel ratio of 0.25,mole fraction of synthesis gas is analysed for increasing gas-fuel ratio of 0.25,0.5,0.75 and 1.0.With increasing gas-fuel ratio from 0.25 to 1.0,the mole fraction of components of synthesis gas does not vary,whereas the heating value and cold-gas efficiency of synthesis gas produced decreases.Considering the emissions,simulated results present co-gasification as better option over conventional systems.Reduction of two-third in kg of CO2 released per kg of fuel was observed with almost three-fourth decrement in kg of CO2 per kWh of power produced.Also,zero SOx and NOx emissions were observed compared to coal based thermal power plants.Simulation of the gasification cycle with varying parameters is carried out using Matrix Laboratory(MATLAB).
