• No liquid effluent formation;• Capability to accept all types of coals;• Better reliability and control;• Operates in non-slagging mode unlike entrained bed gasification;• Best suited for high-ash Indian coals; and• Lower capital and operating costs compared with entrained bed gasifier.BHEL has also built a pilot 6.2 MW integrated gasification combined cycle (IGCC)plant and there is a proposal for a scaled-up 182 MW demo plant as well. As theclimate change is pressing for cleaner power generation and as the reliability of IGCCprocess is increasing, it is clearly evident that IGCC will be one of the future technologiesfor green power generation. IGCC plant cost is higher at this point of time as comparedwith PC boilers without gas cleaning. However, as the emission standard and carboncapture increases, IGCC plant will have more advantage. Improvement and developmentin technologies like gas turbines, hot gas clean-up and gasifiers will make IGCC morecompetitive for power generation. BHEL has gained significant experience via continuousoperation of the gasifier island for the past one year and is now geared fully to commercializethe technology for higher size plants.92
