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.

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.

Cavallo integrated ultra low nitrogen burner

Cavallo integrated ultra-low nitrogen burner has the European advanced low-nitrogen combustion technology, SIEMENS flue gas recirculation FGR technology and control system, easily achieve 30mg ultra-low nitrogen oxide emission standards.
