Top 5 Ways to Increase The Efficiency of Your Boiler

The industrial boiler system is an important piece of equipment, irrespective of where it might be housed. Industries utilize it as a heat source which can be used to power a lot of heavy machinery such as turbines. In commercial and residential setting, they are being implemented to provide with hot water instead of steam. Irrespective of the fact how the industrial boiler system is being used and what type it is of, there are certain key points which can be implemented to enhance the productivity and the efficiency of the boiler unit. 

#1. The Content of Oxygen in the Combustion Mixture: This point ensures that there is excess air in the combustion mixture. The term excess air denotes the volume of air in the combustion mixture which is greater than the total theoretical volume of air required to oxidize the fuel completely. This air ensures that the fuel will undergo complete oxidation and the maximum amount of heat can be generated from the reaction. Excess air also ensures if the combustion reaction is sufficiently oxidized. This means that the flue gas will carry reduced amounts of nitrogen oxides and carbon mono oxide. The demerit of the excess air lies in the fact that excess amount of “excess air” often carries away a significant portion of the heat generated from the reaction thus decreasing the efficiency overall.

#2. Flue Gas Temperature:  The temperature of the flue gas indicates the loss of energy through its dissipation. Higher flue gas temperature indicates that there is a loss of heat energy through the flue gas.

#3. Heat Losses Through Natural Means: This point concerns about the loss of heat energy via convection and radiation. The energy dissipation by these methods cannot be totally avoided but can be controlled to some extent through superior insulation and regulated heat flow.

#4. Fuel Specification: Essentially most of the industrial boiler systems are made of on the basic principle of combustion and generation of heat energy. This means the boilers are designed and fabricated keeping a specific fuel in mind. A Larger amount of hydrogen in fuel is generally avoided as on combustion this hydrogen gets converted into the water which absorbs and dissipates a huge amount of the generated heat, thus reducing the overall efficiency.

#5. The Temperature of the Fuel: Although the temperature of the fuel is not an important factor, it has been found to play an important role in the efficiency of the fuel. A majority of the manufacturers suggest keeping the fuel at an ambient temperature of 21 to 26.

Here Are Some Tips Which Can Be Applied to Increase the Overall Efficiency Of The Boiler:

#1. Regular Maintenance: If you wish that your industrial boiler system functions the way you want it to, the best and assured method is to get the boiler maintained and serviced by a qualified technician. A good and regular maintenance program will improve boiler efficiency, reduce the operational damages to the boiler and operating cost and increase the reliability of the machine.

#2. Operating with the Proper Amount of Excess Air: Inadequate amount can lead to shooting and formation of explosive flue gases. This can be checked by checking the output flue gas for the amount of carbon dioxide and other reactive insufficiently oxidized gases. 
  • Installation of the turbulator can aid a lot in the heat transfer mechanisms of fire tube boiler. This is done maintaining a turbulent flow in the boiler. 
  • The burners should be checked often to check their condition. These often degrade over the time and might need replacement sooner than you think.
