With a large flow of tourists, Zhengzhou Railway Station is one of the eight transportation hubs in China. It is known as the heart of Chinese railways. The comfortable waiting environment comes from stable heating system. It is Zhengzhou Heating Company Second Road Heat Source Factory that provides stable heat source for Zhengzhou Railway station. Founded in 1989, the heat source factory was put into operation in 1992. In recent years, with the aging of old boilers, the thermal efficiency of the existing 4 sets of 20 tph chain grate steam boilers has been gradually reduced. Besides, considering environmental protection and other factors, Second Road Heat Source Factory decided to implement the Coal-to-Gas Project, dismantle the existing low-efficiency and high-consumption coal-fired boilers, and introduce some sets of SZS series gas-fired steam boilers.
Founded in 1818, Libbey Inc. is a large manufacturer of glassware and it is also the standard maker of catering glassware industry in North American. With over 1 billion annual output value, Libbey operates 6 glass manufacturing factories in 5 countries on 3 continents. Libbey (China) Co., Ltd. was set up to develop the Asia-Pacific market. The glass tableware factory located in Langfang Hebei Economic and Technological Development Zone was put into production in early 2007. Its production capacity was up to 100 million per year. As a global company adhering to sustainable development, Libbey decided to update the existing gas-fired boilers to achieve low NOx emissions.
ZOZEN has been implementing the Belt and Road initiative all the time. Qingdao United Zhenye Energy Saving Technology Co., Ltd carried out an in-depth cooperation with Kazakhstan on environmental protection technology of oil fields. ZOZEN provided stable and efficient thermal energy for the project. The first batch of YQW series thermal oil heaters and WNS gas-fired steam boilers has been delivered to Kazakhstan. It indicated that ZOZEN has got the affirmation of users in Kazakhstan again.
ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
Industrial boilers provide a stable steam heat source for the drying, rolling, and vulcanization of tire processing. ZOZEN has reached cooperation with many rubber products manufacturers with high quality products. Sichuan Haida Rubber Group Co., Ltd. is an enterprise integrating R&D, operation and production of automobile tires, products include all-steel commercial radial tires, semi-steel passenger radial tires and oblique commercial tires.
Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
Founded in 1933, Luzhou North Chemical Industries Co., Ltd. is a comprehensive large-scale chemical enterprise. Its main products are military products, cellulose derivatives and silicone series. The production and processing of military and civilian products rely on the support of steam. Therefore, the boiler has become one of the important energy equipment on the production line.
The processing of agricultural products requires a lot of procedures, and steam. Is demanded for the procedures of disinfection and aseptic packaging. Therefore, steam boilers are important equipment. Agra Feed S.A.S. was established in 2011. It is an enterprise in Colombia, operating in the Farm Product Raw Material Merchant Wholesalers industry. In recent years, due to the continuous expansion of the company's production capacity, Agra Feed S.A.S. urgently needed to purchase one set of energy-efficient steam boiler.
