High-efficiency furnaces typically utilize mono-port burners due to their design, which allows for better combustion efficiency and greater control over the air-fuel mixture. These burners are designed to ensure that the combustion process occurs more completely, resulting in less unburned fuel and lower emissions. This is particularly important in high-efficiency systems where maximizing energy usage is a primary goal.

Mono-port burners operate by providing a single port for fuel to enter, which can be better calibrated for optimal performance in high-efficiency applications compared to other burner types that may have multiple ports. The single port allows for a more uniform flame and reduces the chances of incomplete combustion, thus enhancing the overall efficiency of the furnace.

In contrast, dual-port and single-port burners may be employed in standard efficiency systems where less precise control is acceptable, while burner blocks are typically found in different types of heating equipment not specifically designed for high-efficiency applications. The design and operation of mono-port burners are key to achieving the higher efficiency ratings that characterize modern furnaces.
