Boiler Efficiency: Introduction and Methods of Calculation

Combustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.

How clean is your steam? How to ensure the correct process

While there are no standards governing plant steam quality, it is important that the steam is clean, dry and free from boiler carryover. Dirty, wet steam will result in poor heat transfer and potential process control issues. Over a prolonged period, this may affect plant performance, and increase maintenance and operational costs.
