What Factors Affecting Coal Fired Boiler Efficiency
The efficiency of a coalfired boiler depends on the loss of the boiler, the best efficiency in the boiler can be achieved if the losses are kept to the minimum. Since 50% of the losses are dependent on the fuel and ambient condition, the best efficiency can be achieved by properly tuning the other 50%, mainly carbon loss and dry gas loss.
