What is the consequence of incomplete combustion in boilers?

Incomplete combustion in boilers leads to the production of higher emissions and unburned fuel. When combustion is not complete, not all the fuel is converted into usable energy; instead, some fuel remains unburned. This results in the release of pollutants such as carbon monoxide, particulate matter, and other hydrocarbons into the atmosphere, which can negatively affect air quality and contribute to environmental issues.

In addition to higher emissions, there is also a loss of potential energy in the form of unburned fuel, which translates into inefficient operation of the boiler. As a result, the overall efficiency of the boiler decreases, which increases fuel costs over time, as more fuel is needed to achieve the desired output. Thus, higher emissions and unburned fuel are significant consequences of incomplete combustion.
