The study looked into how coal can be used more cleanly in power plants in India. They investigated a technology called IGCC that changes coal into a gas form before burning. This can help reduce carbon emissions. The researchers used computer models to see how an IGCC power plant reacts when coal flow changes. They looked at different parts of the plant like the gasifier, boiler, and turbine. Their goal was to see how altering coal flow affects the plant's performance. The findings showed that changing the amount of coal going into the gasifier impacts how well the plant works. This helps in understanding how to run these cleaner power plants efficiently and effectively.
