At present, FANGKUAI has more than 100 patented technologies, including ultra speed cooling tubes, automatic sewage discharge, scale detection, PLC automatic control system, corrugated furnace, enamel liner, boiler water level controller, intelligent oxygen content adjustment and other technologies. The researches have won the national technical patent certificate.
Scientific research investment of not less than 5% of the total turnover per year.
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.
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%.
Except traditional four pieces of water level control, the fifth water level detection is added, which is more sensitive to water level changes.
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.
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.
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.
