Regenerative burner 1150 series

natural gasindirectly firedlow-NOx

The 1150 Series LumiFlame Regenerative Burner is the most advanced development in low NOX combustion technology and fuel efficiency. High fuel efficiency is achieved through regeneration using a pair of burners which cycle to alternately heat the combustion air or recover and store the heat from the furnace exhaust gases. When one burner is firing, the other is exhausting the furnace gases. Exhaust gases pass through the burner body and into a media case, which contains refractory material. The refractory media is heated by the exhaust gases, thus recovering and storing energy from the flue products. When the media bed is fully heated, the burner currently firing is turned off and begins to exhaust the flue products. The burner with the hot media bed begins firing. Combustion air passes through the media bed and is heated by the hot refractory. Air preheat temperatures within 300°F (149°C) of the products of combustion are achieved resulting in exceptionally high thermal efficiency.
