In recent years, there is an increasing concern of biogas. As an advocate for the green development of the industrial boiler industry, ZOZEN overcame the technical difficulties and launched new type biogas-fired steam boilers. With sufficient output and high thermal efficiency, the boilers bot only saved a lot of fuel costs for users but also effectively promoted the development of circular economy.
ZOZEN WNS series gas-fired boiler has a compact structure. The boiler is stable and reliable. It adopts a large-diameter corrugated furnace to ensure sufficient steam storage space and heating area. The heat transfer coefficient of threaded flue tubes is 1.2 times higher than that of ordinary flue tubes. Besides, energy-saving devices were equipped at the tail of the flue to improve the inlet water temperature, reduce the exhaust gas temperature and increase the thermal efficiency to more than 98%, which realized the goal of energy saving and emission reduction for many locomotive depots.
ZOZEN has always been devoted to the improvement of quality and service. According to the actual working conditions of Changchun Huatao, ZOZEN not only reasonably designed the WNS series gas-fired boiler system but also completed the lean Manufacturing of the boiler. From the blanking, drilling, welding to bending, all the processes adopted advanced technology to achieve refined production. It is the rigorous attitude to detail that makes the high quality and high performance of ZOZEN.
At present, the two sets of SZS series gas-fired boilers have arrived the project site of Baoding Swan New Fiber Manufacturing Co., Ltd. The hoisting of the boiler proper has been completed smoothly. And, the boilers have entered the auxiliary infrastructure construction phase. ZOZEN installation team will strive to complete the project instruction within the agreed time and ensure the smooth delivery of the EPC turnkey project.
In response to the question, senior engineers who have engaged in industrial boiler technology analyzed the essence of energy-saving and environment-friendly boilers from four aspects, including the condition of fuel combustion, boiler heat dissipation, exhaust temperature and emission indicators.
ZOZEN fully considered the effects of altitude and atmospheric pressure on gas-fired steam boilers when designing the boiler system solution. On the one hand, owing to the decrease of atmospheric pressure, the combustion speed of fuel slowed down. The designers of ZOZEN properly increased the furnace volume and the convective heating surface area to ensure the heat transfer effect. On the other hand, the air volume and pressure should be modified when selecting a burner, which can ensure the boiler output and the thermal efficiency of the entire boiler system.
Recently, the ZOZEN gas-fired boiler for Nanjing King Long Bus Manufacturing Co., Ltd., an electric vehicle leader, has been put into operation smoothly and has become the important heat source for the new energy vehicle production line.
At the parade of the 70th anniversary of the China National Day, the uniform and magnificent array of squares was amazing. All aspects of logistics support are indispensable for a grand military parade. ZOZEN has provided sufficient heat source support for the weaving, printing and dyeing process of military fabrics.
Chongqing No.3533 Printing Dyeing and Clothing Co., Ltd. is a large-scale military-needed textile, printing and dyeing enterprise. Its products sell well all over the world such as Britain, Italy, the United States, Spain, etc. The company not only has a number of printing and dyeing production lines, but also can perform anti-infrared, anti-static, flame-retardant and other functional finishing according to the needs of users. In the process of fabric printing and garment processing, printing, dyeing, heat setting, drying and other processes require a stable steam heat source provided by the boiler.
