Steel rolling heating furnace burner: a "package" solution

1、 Energy saving principle of regenerative burner and regenerative steel rolling heating furnace:

A regenerative burner is a type of burner that uses a regenerative ball (or honeycomb) to recover heat from the flue gas of a steel rolling heating furnace to preheat air and achieve alternating combustion and uniform heating. The regenerative burner is mainly used in steel rolling heating furnaces. Known for its low NOx emissions and high combustion thermal efficiency. It is another major technological advancement after the self preheating burner. Regenerative steel rolling heating furnace burner: After connecting the heat exchange system with the burner and installing it in pairs on the side wall of the regenerative steel rolling heating furnace, it is then operated in pairs through a directional valve.

A set of regenerative burner system shall at least include: two burners, two heat accumulators, a heat recovery system, and corresponding fully automatic control system. The burner and heat accumulator can be directly connected together according to the actual situation on site or alternatively connected together using pipes cast with refractory materials.

When one burner uses the hot air in the heat accumulator for combustion, the other burner functions as a smoke exhaust port, using a smoke exhaust fan to extract the hot air from the furnace and store heat through the burner into the heat accumulator. When the heat is fully stored, the butterfly valve acts to switch the functions of the two burners. Whenever one burner is burning, the other is helping the heat accumulator to store heat. In heat exchange, the temperature of the exhaust gas in the pipeline is usually between 150 and 200 ℃, so both butterfly valves and smoke exhaust fans can work reliably for a long time within this temperature range. Proper installation and selection of regenerative burners can successfully save 70% of energy and improve combustion efficiency by 90%.
