Ultra-low NOx condensing steam boiler is a two passes fire tube boiler with wet back, high efficiency, low stress. It is integrated with high efficient air preheater and condenser. Two arc doors are in the front. Larger combustion chamberand thread fire tubes increase the heat transfer. Initiation of low NOx coupling technique and unique four levels of low NOx combustion technology completely inhibited the production of NOx; equipped with ABB inverter from German, Cavallo dual-bloc ultra-low NOx burner from Italy, 7/10 inch LCD touch screen and PLC programmable controller to guarantee the emission of NOx≤30mg/m3.

KENUOUltra-low NOx condensing steam boiler

Working principle:

The boiler has large corrugated furnace, wet backand full threaded tubes symmetrically located on both sides of the furnace. Cavallo ultra-low NOx dual-bloc burner is installed inside the furnace. Flue gas is reverted into the 2nd pass tubes at the back chamber. After heat exchange, flue gas enters into the air-preheater, where it counter-flow heat exchanges with the combustion air. Then the flue gas goes into the condenser to heat up the feed water, recovering all the sensible and latent heat. Finally the glue gas exits from the chimney to the air.

Two Passes Design

The optimized two passes design enlarged the heating surface on the 2nd pass and steam drum, which provides a better steam quality.

 

Large Corrugated Furnace

Balanced heat exchange and water level & steam pressure more stable;

Larger combustion chamber, reducing the flame temperature, guarantee NOx≤30mg/m3 emission.

 

Cantilever Air-fan and Stainless Steel Silencer from Cavallo Italy

Compact size, light weighted, stable air pressure and flow, stainless silencer to decrease noise emission.

 

Integrated Economizer and Condenser 

Recover both the sensible and latent heat from the flue gas, to heat up the feed water and save energy cost, boiler efficiency can be increased up to 103%.

Made in ND steel and finned tubes in silicon magnesium aluminum alloy. Enhanced heat exchange and anti-corrosion ability.


Air-preheater

It can start to heat up the combustion air fast at low temperature;

Good heat exchange and anti-corrosion ability;

Counter-flow heat exchange, efficient heat transfer to heat up the air and accelerate the combustion, which efficiency can be up to 99.99%


Ultra-low NOx Dual-bloc Burner from Cavallo

Ultra-low NOx burner from Cavallo Italy has many combustion technologies, such as fuel three-stage distribution technology, air four-stage mixing technology, premixing technology. FGR technology etc, to make the burner more stable; Integrated with Cavallo FGR technology to guarantee an ultra-low NOx emission of 30mg/m: Equipped with Siemens LMV5 electronic cam and ABB inverter, to have High- precision adjustment, smooth transition on full loads; safer, more efficient, less energy consumption.

 

Feed Water with Inverter

Stabilize feed water, automatically tracking the steam load to adjust the feed water quantity; stable boiler water temperature, less fluctuation; stable steam pressure; high quality of steam.

 

PLC Smart Controller

High resolution touch screen, large storage, compact with PLC controller; Start/stop button; with water level/ pressure /temperature alarm and interlock functions, it can effectively record the operating state of the boiler and monitor the safety of the boiler. Can communicate with upper control system or DCS with Modus RS 485 protocol.

1.Oval Shape Reverse Chamber

Oval shape reverse chamber allows a larger drum size, which increases the steam quality, dryness up to 99.83%.

2.Air-preheater

Air-preheater increases heat recovery.

It can start to heat up the combustion air fast at low temperature, preventing the condensation corrosion to the burner and boiler.

Finned tubes in silicon magnesium aluminum alloy, with good heat exchange and anti-corrosion ability;

Counter-flow heat exchange, efficient heat transfer to heat up the air and accelerate the combustion, which efficiency can be up to 100%

Boiler efficiency increases up to 3%.
