How to increase boiler efficiency without any investment

Boiler engineers 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. 

25 ways to increase boiler efficiency

  1. Control excess air in your boiler. A 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 the boiler tube 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 the 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.increase boiler efficiency
  6. Controlling boiler blowdown Losses.
  7. Controlling boiler condenser Losses.
  8. Installing Insulation on the Boiler and pipeline 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 levels 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 operators can reduce the running cost of the boiler.
  18. Adopting New Trends, and Innovations in Technology By sharing knowledge with Multiple Industrial units & Engineers.
  19. Perform regular maintenance: Regularly maintaining your boiler can help it run more efficiently and extend its lifespan. This includes cleaning and inspecting the system, checking and replacing the air filters, and ensuring all controls are functioning properly.
  20. Insulate your boiler: Proper insulation can help your boiler run more efficiently by reducing heat loss. You can add insulation to the pipes, tanks, and any other exposed areas to help keep the heat in.
  21. Upgrade your thermostat: If you have an older thermostat, it may not be as accurate as newer models. Upgrading to a programmable thermostat can help you better control the temperature in your home and reduce energy waste.
  22. Use low-energy lighting: If your boiler is in a room with a lot of lighting, consider using low-energy bulbs to reduce the heat output. This can help reduce the workload on your boiler, improving its efficiency.
  23. Seal any drafts: Drafts can cause your boiler to work harder to heat your home, leading to reduced efficiency. You can use draft stoppers or weatherstripping to seal any gaps around doors and windows to help keep the heat in.
  24. Use a power flush: A power flush is a process that involves cleaning the inside of your boiler and heating system to remove any build-up of dirt and debris. This can help improve the efficiency of your system and reduce energy consumption.
  25. Install low-flow showerheads: Low-flow showerheads use less hot water than traditional showerheads, which can help reduce the workload on your boiler. This can help improve its efficiency and save you money on your energy bills.
