Based on sophisticated oil-gas fired boilers production experience, our WNSL sries oil-gas fired boilers are used for ecological power generation through years of cooperation with famous domestic scientific research institutions and universities. Based on the operation data of the company’s existing oil-gas fired boilers, we have developed the latest condensing oil-gas fired boilers which is high-efficient, energy-saving and environmental friendly. The latent heat of vaporization is recovered by using a large amount of water vapor contained in the flue gas after natural gas combustion, so as to improve the boiler efficiency to more than 100%. Suitable for natural gas, light oil, heavy oil and other fuels, it is widely used in garment factories, hospitals, schools, hotels, pharmaceutical factories, food factories, beverage factories, rubber factories, chemical plants, paper factories, building materials industry, etc. With the advantageous features of boiler such as high efficiency, energy saving and environmental protection, it is favored by more and more enterprises. Sifang Boiler has built a professional oil and gas furnace production line, which realizes the automation of boilers from feeding to processing, welding and then assembling, ensuring the quality of boiler products as well as the production cycle, escorting for the scale production of enterprises.
