Figure 1 shows the boiler efficiency with the GCV of the coal. As the coal used with higher GCV, efficiency is increased. Lignite coal with 4300 kcal/kg gives a % in this boiler, while semi bituminous coal with 5800 kcal/kg gives % efficiency in this boiler. So as the higher grade coal is used, efficiency will be increase.
