One of the most severe problems is the regurgitation of hot furnace gases or a boiler explosion moving backwards through the transfer pipes. Because of the process and volatility of pulverized coal, explosions can happen within the boiler feed system and flow backward as far as the conveyer therefore, the use of a gate or a valve on the transfer pipes is necessary to prevent the gases or
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.
