Split ultra-low nitrogen burner with variable frequency proportional combustion technology

The split burner adopts electronic proportional regulation and air staged combustion technology to form three combustion zones in the large furnace. That is, the pyrolysis zone, the oxygen-poor zone and the oxygen-rich zone. The entire combustion process reduces the generation of thermal NOx, while suppressing the generation of fuel NOx, reducing the total NOx emissions, and achieving the requirements of high-efficiency low-NOx combustion. The low-nitrogen burner can control NOx to 30~80mg/m³ within the full fire range.

Runway shape reversal chamber

Reversal chamber adopted runway shape, compared with tradtional round shape，this structure greatly increased steam space, makes the steam dryness up to 99.83%, ensure the steam quality. (Increase the upper steam rising space, steam production space, and steam storage space).

Kenuo independently developed built-in Air preheater 

Start quickly at low temperature, fast heat exchange, prevent condensation of flue gas from corroding the burner and boiler.

Adopt high-efficiency smoke and air heat exchange tubes with high heat exchange intensity and strong corrosion resistance.

Bidirectional pure counter-current heat exchange mode, instantly increases air temperature, accelerates and strengthens combustion, at the same time strengthens radiation heat exchange in the furnace (improves efficiency), combustion efficiency of up to 99.99% (higher burnout rate).

Boiler thermal efficiency increased more than 3% than without air preheater.

Full corrugated and extended furnace, super large furnace design, low center layout structure

The design of the super-large corrugated furnace is perfectly matched with the combustion flame, increase the combustion space and reduce the flame temperature, effectively inhibit the generation of nitrogen oxides; Boiler water is heated evenly, and the water level and steam pressure are more stable, it is the perfect design combination of flame combustion and energy conversion, perfect combination of boiler and furnace.

Air-cooled jacketed smoke box

The air preheater mixes with fresh air and brings the internal heat back to the furnace through the air-cooled flue of the smoke box, thereby reducing heat loss, lowering the surface temperature of the front smoke box (the front smoke box does not need to be made of refractory cement), reducing erosion and wear, and extending the service life of the boiler. .

Economizer & condenser integrated machine

Material：ND Steel+Silicon-magnesium-aluminum alloy fin tube.

Feature：Better heat transfer performance and high heat exchange intensity,Stronger acid corrosion resistance

Effect：Efficient operation, effectively improving boiler thermal efficiency and saving energy.

Principle: The sensible heat in the flue gas and the latent heat of condensation of water vapor are recovered to the maximum extent, the exhaust temperature is reduced; Fin tubes are arranged in staggered rows to utilize the flow of flue gas to flush out the flue gas condensed water attached to the tube wall and fins in a timely manner, stripping and discharging them, thereby strengthening the water vapor condensation heat exchange in the flue gas. So the thermal efficiency of the boiler is improved, and NOX emissions are reduced.

Intelligent power-save automatic control, save energy up to 30%

Adopt Swiss brand ADD inverter, perfect combination with combustion fan , feed water pump, and optimized PLC automatic control, boiler load meets the full-proportional personalized output. Wide frequency conversion makes the motor output more power-saving, energy-saving and stepless adjustment. Besides boiler water replenishment as required, meet load changes and maintain pressure stability.
