Ultra-low nitrogen emission boiler China's first boiler   Successfully Applied FGR combustion technology

In 2014, it passed the ultra-low NOx emission test and was the only designated boiler partner for the APEC Summit. It is the first ultra-low nitrogen boiler in China that has been successfully developed and put into use.

China's first boiler
Core Technology

Ultra Speed Cooling Tube Technology

The unique wing groove structure increases the heat exchange area by 5 times, heat transfer is faster, heat loss is smaller, and the area covered of boilers is reduced by more than 40%.

5th Water Level Detection Technology

Except traditional four pieces of water level control, the fifth water level detection is added, which is more sensitive to water level changes.

PLC Intelligent Control System

The device is independently designed and developed by FANGKUAI. The system is stable and very sensitive. It can respond to changes in heat, burner load and water pump during boiler operation.

Corrugated Furnace

The corrugated furnace structure not only increases the heating area of the furnace, but also alleviates the damage caused by thermal expansion and contraction to the combustion chamber.

Enamel Liner

Inner food-grade coating, fully meets drinking water standards; and has anti-corrosion, anti-rust and anti-scaling functions to ensure no rust, thus extending boiler life.
