The ZOZEN 4 tph WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace, which increases the heat transfer surface, reduces the thermal stress and improves the boiler safety. Meanwhile, in order to reduce the heat loss due to exhaust gas and operating costs, ZOZEN also installs the energy-saving equipment at the end of the flue gas duct to ensure boiler's thermal efficiency reaches 98% and above. What's more, WNS series boilers also have the characteristics of fully automatic intelligent control and easy operation to ensure boiler's long-term, safe and stable operation, so they are well received by users at home and abroad.
Relying on the scientific and technological innovation and cooperation with Shanghai Jiaotong University, ZOZEN Boiler develops the new generation of biomass boilers, which not only solves the problems such as the furnace arch and door burning out, hopper burning and feed stopper coking, but also improves the biomass boiler performance.
The boiler is a kind of special equipment and the compressive strength of boiler can directly affect the boiler safety performance. ZOZEN Boiler insists on putting quality in the first place to conduct the strict strength re-inspection on the boiler manufacturing materials newly purchased in order to ensure the compressive strength of boiler fundamentally and escort the safe operation of boiler.
The welding of horizontal fixed tubes is to weld the tubes which are put in the horizontal or nearly horizontal position. This kind of welding includes three spacial positions: upright, vertical and horizontal (all-position), which puts forward high requirements for the welding technology. Facing the difficulties brought by welding appearance requirements, curvature of tube joint, and small tube diameter, ZOZEN workers are skilled in welding to ensure the welding quality to effectively extend the service life of boilers.
Affected by the global COVID-19 conditions, many enterprises change their offline business to online business. To solve the problem of communicating with overseas customers, ZOZEN Boiler has purchased a complete set of video conference equipment to keep a smooth communication with overseas customers. Recently, ZOZEN Boiler has organized a video conference with a Korean customer about the circulating fluidized bed boiler project. ZOZEN's general manager Zhang, sales vice general manger Liu, boiler designer Yang and domestic sales manager Wang attended the conference.
ZOZEN guides and cultivates different kinds of talents according to their different characteristics and laws of growth. In late July, ZOZEN Boiler launched a three-day job training program for new graduates, which was held by the vice general manager and boiler designer, Zhu Qiuping. As a senior boiler engineer, vice general manager Zhu has more than 30 years of experience in boiler design, especially in designing large-scale circulating fluidized bed boiler and gas-fired boiler. He is now the head in charge of ZOZEN Boiler's R&D and design department and is one of the representative persons of ZOZEN Boiler's "soft power".
ZOZEN Boiler has guided the industrial boiler manufacturing quality for decades. It also has established the technology standards of blanking digitization, automation of welding and assembly moulding to realize the specialized and scale production of boiler's main parts. For further improving the boiler production efficiency and product quality, ZOZEN's Yixing factory introduced a series of new equipment including laser cutting machine, grooving machine, blending machine and sand blasting machine.
Shandong Luhua Group Co., Ltd. is a national key leading enterprise of agricultural industrialization in China with 24 production bases and covers industries of edible oil, condiments, vegetable processing and so on. Its annual production capacity of edible oil is 1 million tons and that of condiments is 100,000 tons. ZOZEN's SZS series gas-fired steam boiler and SZS series low NOx gas-fired saturated steam boiler have sufficient heating surface and enough steam and water space to ensure the stability of boiler indexes. Meanwhile, full membrane wall structure can ensure excellent airtightness and thermal efficiency (above 98%). ZOZEN Boiler also adopts ultra low NOx burner via flue gas circulating can ensure the complete combustion of fuel and control the emission of NOx at the same time. It is estimated that boiler's NOx emission is less than 28mg/m3, which completely meets the standards of Environmental Protection Department of Shandong Province.
