foshan city nuo a combustion control technology co., ltd., ten years focus on combustion system automation production.

The use of flue gas, through the internal displacer preheating combustion air, due to the heat exchanger using the best shape design, can obtain a very high heat exchange efficiency, flame ejection speed is high: max120-160m/s, open flame heating, specially designed flue gas ejector to ensure that 100% of the flue gas discharged from the burner.

Direct electrode electric fire, flame detection adopts ionization or ultraviolet UV mode, multi-stage combustion, frequent ignition is reliable, the heat exchanger with low harmful substance content in flue gas adopts metal or ceramic materials, the heat exchanger has various standard lengths, the heat exchanger has the best structural design, the heat exchanger has high efficiency, energy saving, the air preheating temperature is as high as 700°C, and the burner adopts pulse mode, which can obtain higher temperature uniformity and service life.

 

Application place of burner
Regenerative burner for gas: natural gas, liquefied gas, coke oven gas, mixed gas, producer gas.


Regenerative burners combined with heat-resistant steel metal or ceramic silicon carbide radiant tubes and silicon carbide ducts are applied to products that require flue gas to be isolated and heated or to be heated in a protective atmosphere environment, such as non-oxidizing roller low furnace, protective atmosphere mesh belt furnace, continuous annealing line, etc. When applied to radiant tube indirect heating system, the common radiant tube types are P type and W type.

Regenerative burners are often combined with flue gas ejectors and flue gas casings and other applications in energy-saving direct energy direct heating systems, mainly used in iron and steel, non-ferrous industries and other industrial furnaces and combustion systems, such as chamber furnaces, trolley furnaces, bell furnaces, rotary hearth furnaces, ceramic roller kilns and so on.

Equipment Development of Industrial Furnace

High-grade industrial products have higher requirements for the average temperature field in the furnace, and higher requirements for the non-chaotic controllability of the combustion atmosphere, which cannot be achieved by using traditional continuous combustion control. With the rise of wide-section, large-capacity industrial furnaces, pulse combustion control technology is necessary to control the average temperature field in the furnace.
