What can result from carbon deposit buildup in the combustion chamber?

The buildup of carbon deposits in the combustion chamber can lead to burner failure. Over time, these deposits can interfere with the proper combustion of fuel, affecting the burner’s operation. When carbon accumulates, it may obstruct air and fuel passages, reducing airflow and efficiency, and ultimately causing the burner to malfunction or fail altogether. If left unaddressed, severe carbon buildup can even lead to hazardous conditions, requiring significant repairs or replacement of the burner system.

Other options suggest outcomes that are positive or beneficial, which do not align with the negative impact of carbon deposits. For instance, improved efficiency, enhanced heat output, and reduced emissions are not results of carbon buildup; instead, these conditions are typically associated with a clean and properly functioning combustion environment.
