Regenerative Burners
A regenerative combustion system uses a pair of burners, each of which has a media case filled with dense ceramic material, which periodically alternate between firing and exhausting. When exhausting, hot combustion products are pulled from the furnace through the burner head and its accompanying media case, increasing the temperature of the ceramic media close to the furnace temperature. When firing, cold air flows through the media case, increasing in temperature to provide oxygen for combustion. After a set period, the burners “cycle” and the previously exhausting burner transitions to firing mode. Regenerative burners capture and return most of the energy contained in the furnace’s waste gases, thereby providing exceptional fuel efficiency for high process temperature applications.

Baffle Burners
Baffle burners consist of a body, gas nozzle, baffle, and port. Baffle burners recirculate furnace exhaust gases into the combustion envelope to limit peak flame temperatures resulting in reduced NOx formation. Baffle burners can run on many types of gaseous and liquid fuels, and they are often designed for multifuel compatibility to increase flexibility for users. Combustion air enters the burner body and is separated from the fuel, which passes through the body inside a fuel tube, until mixing immediately after the baffle. Because fuel and air are not mixed until they exit the hot side of the baffle, flashback is minimized allowing for high turndown and application to fuels with high flame speeds such as hydrogen. The refractory baffle separates and protects the gas nozzle and burner body from the furnace’s thermal radiation, yielding long service life with minimal maintenance.

Air Staged Burners
Air Staged Burners are a Baffle Burner variation that introduce portions of the combustion air at different locations relative to the fuel to delay mixing and decrease peak flame temperatures. Air staged burners tend to have larger flames compared to non-staged and premix burners of the same capacity but produce much lower NOx.

Premix and Partial Premix Burners
Premix burners are often used on boilers, air heaters, or ultra-low NOx specialty heat treating applications. Combustion air and fuel are combined before exiting the baffle, differentiating premix from other burner types. One advantage of Bloom premix burners is their very low NOx emissions, especially when operated with moderate levels of excess air. Turndown and fuel compatibility are more limited due to the potential for flashback.

Self-Recuperative Burners
Self-Recuperative burners incorporate an integral recuperator with the burner which preheats the combustion air. The exhaust gases are ‘pulled back’ through the burner by an eductor or an exhaust ‘suction’ blower. This design allows for increased thermal efficiencies in furnaces where a centralized recuperator is not practical. Bloom Engineering can also pair recuperators with many of its small capacity hot air burners (such as 1500S) for applications where the flame shape or NOx levels of self-recuperative burners are not optimal.
