The shortcomings of traditional boiler is high consumption, high emission, which cannot meet the demand of industries now. So improving the efficiency of industrial boiler is the most important thing for every enterprise.

Boiler efficiency is a measure of how much of the energy used by the boiler is converted into usable heat. It determines the amount of fuel that is needed to produce a given amount of heat, and thus affects the cost of operating the boiler. If the boiler is not operating efficiently, it will use more fuel, leading to higher fuel costs.

In industrial production, the efficiency of boiler directly affects the energy utilization rate and operating cost.There are many factors that affect boiler efficiency,let us discuss in this article.

Affect Factor

1.Fuel type

Fuel type affects combustion effect, drying treatment can reduce the water content of fuel,increase the combustion temperature and reduce the generation of noncombustible gas. Crushing homogenization ensures the fuel particle size is moderate, optimizes the combustion rate and reduces the combustion loss.

2.Control system

Advanced control system can monitor and adjust the combustion process in real time and improve the combustion efficiency of the boiler.Adjust air flow and furnace temperature,reduce energy consumption and improve system efficiency.

3.Pressure and temperature

Deviate from specific pressures and temperatures in the production process,will cause loss of energy and decrease in efficiency.

4.Excess air

Excess air in combustion refers to the amount of air that is introduced into the combustion process beyond the theoretical amount required for complete fuel combustion.Proper excess air reduces pollutants like carbon monoxide, but excessive amounts can lead to reduced efficiency and energy waste.

Solution Measure

1.Install economizer

Incorporating heat recovery into a boiler system will improve efficiency, and an economizer can increase efficiency obviously. Depending on the boiler type, fuel used and operating conditions, a standard or condensing economizer can be installed.

2.Upgrade to full modulation burner

Using this tech, boiler don’t turn off and on to maintain their temperature.modulate from low to high fire in response to demand providing accurate output as needed.

3.Control air amount

The amount of air can affect your boiler efficiency. Sufficient air is necessary for adequate fuel combustion in the boiler, but excess air reduces efficiency – a proper air-fuel ratio is one key to peak efficiency.

4.Clean up boiler tube

Boiler tubes may accumulate soot from the fireside.The soot coating acts as an insulator leading to slow heat transfer. This leads to more fuel consumption.Inspect your boiler tubes regularly and schedule regular maintenance to increase boiler efficiency.

5.Water treatment

Water treatment protects heat transfer surfaces and maintains efficient boiler operation.Scaled boiler can lose up to 20% of its efficiency,and if do not  processed,system can suffer from corrosion, component damage and increased energy costs.

6.Enhance insulation

Good insulation measures can reduce heat loss, so that more heat energy is retained in the system.Use highly efficient insulation materials to provide a comprehensive thermal insulation cover for the boiler system,improve the system's thermal energy utilization.

7.Automatic monitoring

Automatic monitoring systems ensure boiler runs at its best,reduce fuel use and environmental pollution,Monitor flue gas O2 and temperature levels to determine combustion efficiency .

8.Install heat recovery system

Capture wasted heat from exhaust gases and transfer it back into the system, increasing overall efficiency.

Conclusion

Energy inefficiency in boilers is caused not only by aging factors but also by heat losses. A less efficient boiler will increase your fuel costs.We hope that the article answer your questions regarding your boiler’s efficiency!
