The designer of a pulverized-coal-fired unit must consider the burner arrangment and the furnace configuration to minimize slagging or fouling of the boiler. An increase in excess air will permit satisfactory performance with most designs, but this may be uneconomical as a long-term substitute for good basic design.

2009/7/5 · 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. There are a few minor losses …
