How to increase boiler efficiency without any investment

You can increase boiler efficiency up to 10% without even spending any penny or up to 15% with spending some money. Take these steps on your steam boiler and you can save a lot of energy, fuel, and money. 

18 ways to increase boiler efficiency

1. Control excess air of your boiler. 5% Reduction in the Excess air can increase boiler efficiency up to 1%, controlling 3 Ts of combustion. (Time, Temperature and Turbulence).
2. Perform soot blowing on time. Fouling of boiler tubes surface by soot will bring about a rise in flue gas temperature. Many boilers require once per shift, it depends on fuel and condition.
3. You can increase boiler efficiency by adjusting Burner air to fuel ratio. It is a good step towards perfect combustion that can save fuel.
4. By increasing combustion air temperature. 20 C rise in Air Pre-heating by waste heat recovery you can save 1% of fuel.
5. Avoiding low primary air velocity.
6. Controlling boiler blowdown Losses.
7. Controlling boiler condenser Losses.
8. Installing Insulation on Boiler and pipeline it can save 2% of fuel.
9. Reducing unburnt fuel, radiant and convective heat losses in the flue gas.
10. Efficient Steam Management, Maintain steam parameters according to turbine design requirements.
11. Prevention of fuel by reducing natural losses like wind and rain.
12. Maintaining Boiler draft according to combustion requirements.
13. Operate boiler within design limits of pressure and temperature & load.
14. Maintain proper safety valve setting.
15. Maintain normal level in the boiler.
16. Don’t feed that chemical in your boiler that you don’t have enough information about.
17. Avoid human errors. Trained personnel operator can reduce running cost of the boiler.
18. Adopting New Trends, Innovations in Technology By sharing knowledge with Multiple Industrial units & Engineers.
