5 Ways to Increase Boiler Efficiency

A boiler appears to be a simple device. It is a closed vessel that heats a fluid and produces vapor or steam. This should make it very simple to get the most out of a boiler. But in reality, things are a little different. A boiler’s components include a burner, heat exchanger, supply lines, refractory, circulatory pumps, deaerators, and many more. As a result, achieving maximum efficiency is a difficult task.

It’s good news that there are measures to increase your boiler’s effectiveness. Check out some of the top approaches we’ve included here.

Improve the Boiler Burners

The boiler’s burners will lose efficiency and deteriorate over time. When this occurs, the burners should be replaced or retrofitted. Numerous burner options are available for replacement, regardless of the type of fuel you use or the industrial boiler you have. Even if you cannot afford new boiler burners, retrofitting the burner may provide significant savings at a fraction of the cost.

Turbulators Should Be Installed

Installing a turbulator in a firetube boiler may be an effective way to increase efficiency. A turbulator is installed inside the boiler tubes, tube heat exchangers, and other heat-transfer equipment.

This device improves heat transfer efficiency by maintaining a turbulent flow through the boiler passes. Turbulators are typically installed in the final boiler pass. Turbulators are one of the most cost-effective efficiency upgrades for older firetube boilers.

Use The Appropriate Excess Air

Boilers can’t function properly without a certain quantity of excess air for full combustion. If the system operates with excessive excess air, it can reduce boiler efficiency by heating and discarding this “cushion” of air. In contrast, running the boiler with no excess air can result in the following:

  • Pollution of the air.
  • Sooting by the fire.
  • Reduced efficiency.
  • Flue gasses that could explode.

You can optimize this air cushion and fine-tune the boiler for maximum efficiency by monitoring the oxygen content, flue gas temperature, and carbon dioxide. There are fixed and portable combustion efficiency tests available, which can be used to adjust combustion air quality.

Regular Boiler Maintenance

Among the most cost-effective ways to keep your equipment functioning well is through regular boiler maintenance. A good maintenance program will improve efficiency, slow boiler deterioration, lower operating costs, and, in the end, ensure reliability. The best way to maintain your boiler is by having a professional service perform inspections. This will ensure that all safety features are working properly and that nothing else in the system is malfunctioning.

Enhance Boiler Insulation

Large commercial and industrial boilers have large surface areas extremely vulnerable to heat loss, especially when improperly insulated. You may be able to improve the efficiency of your boiler by using insulation. Boiler insulation can be applied to the interior and exterior of a boiler. It can reduce heat loss and improve efficiency.
