Details Introduced


Yuanda WNS series gas fired boiler adopts horizontal three-pass wet-back structure, large corrugated furnace and patented thread pipe technology, equipped with international first-line brand burners and valve groups, and independently developed high-matching PLC control system to realize multiple linkages. This boiler adopts wet wet back structure, it can adapt to the high temperature, and increase the radiation heat transfer area and improve the heat transfer efficiency (up to 95% thermal efficiency). 

Our gas fired boiler normally suitable for 300kg to 40ton/h capacity, use all kinds of gas and oil fuels, such as natural gas, LPG, LNG, CNG, city gas, biogas, diesel oil, heavy oil.

Working System:
