1. WNS series of oil fired boiler uses the standard three return trip technology the entire wet back structure.
2.The furnace transfer and breathing tube radiation heat convection rational design, layout of adequate heating boilers, high thermal efficiency.
3.This furnace water capacity, full heat exchanger, especially for medium and large sized boiler.
4.This furnace used to burn the center of a unique technology,the entire wet back structure, the furnace volumn is big. make full use of radiation furnace heat exchanger,and through the combustion of fuels burnout level, making boiler thermal efficiency improved greatly.
5.This simplifies the furnace heating surface design,especially for the low-power boiler.
