The character of this type:WNS sereis of fuel oil gas-fired is the new patented technology boiler which developed independently by our company. This furnace used to burn the centre of a unique technology, the entire wet back structure,the furnace volume is big,make full use of radiation furnace heat exchanger,and through enhancing the combustion of fuel burnout level,making boiler thermal efficiency improved greatly.this simplifies the furnace design,especially for the low-power boiler.
