Assessment of a boiler

• Boiler performance
• Heat Balance
• Boiler Efficiency
• Boiler Blow Down
• Boiler Feed Water Treatment
• External Water Treatment

Energy efficiency opportunities

1. Stack temperature control
2. Feed water preheating using economizers
3. Combustion air pre-heating
4. Incomplete combustion minimization
5. Excess air control
6. Avoid radiation and convection heat loss
7. Automatic blow down control
8. Reduction of scaling and soot losses
9. Reduction of boiler steam pressure
10. Variable speed control
11. Controlling boiler loading
12. Proper boiler scheduling
13. Boiler replacement
