The Importance of Boiler Maintenan

Boilers are typically indispensable pieces of equipment at most industrial facilities. If the boiler fails then all operations at the plant can grind to a halt, stopping production and costing the plant in lost productivity. Boiler Maintenance Increases the Efficiency of the Boiler – Boilers are huge fuel consumers. To keep fuel and energy costs low while maximizing output it is essential that the boiler be operating as efficiently as possible.

How to Run a Coal Fired Boiler at the Best Efficiency .

Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.
