how to efficiency coal in boiler

International Journal of Innovative Research in Science

2015-8-15 · 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 77.51% in this boiler, while semi bituminous coal with 5800 kcal/kg gives 80.20% efficiency in this boiler. So as the higher grade coal is used, efficiency will be increase.

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
