With the continuous development of the building materials industry and the increasing environmental awareness of the whole society, many brick factories in China have conducted the production transition. Ledong Changsheng Standard Eco-friendly Brick Co., Ltd., founded in 2011, has grasped the opportunity to engage in the production and sales of new wall materials, eco-friendly bricks, which earns considerable profits for the company. However, the stable operation of the eco-friendly brick production line depends on the steam supply provided by the industrial boiler, and a set of energy-saving and high-efficiency steam boiler can directly affect the quality of eco-friendly bricks and the economic benefits of the enterprise. Therefore, after a specific investigation on the domestic industrial boiler market, Ledong Changsheng Standard Eco-friendly Brick finally chose ZOZEN Boiler as the boiler equipment supplier.
In recent years, incidents related to food safety is nothing new, of which many are caused by unqualified food packaging. Therefore, food packaging safety issues have received wide attention from many food enterprises and the public. Nanjing Yanzhenwang Packaging Materials Co., Ltd., established in 2012, is a Sino-Japanese joint venture engaged in the production and processing of food packaging and other plastic packaging materials, which needs the support of steam heat source. In order to meet the demands of ever-expanding production scale and respond to the increasingly strict environmental protection policies, Nanjing Yanzhenwang Packaging Materials Co., Ltd. decided to replace the outdated production equipment with the eco-friendly boiler with high efficiency and good energy-saving effect to provide stable and safe heating support for the production line of food packaging materials.
Anda Beituo New Materials Co., Ltd., founded in 2017, is a professional environmental protection engineering enterprise specialized in the development, design, production, sales and services of environment-friendly products. As is known to all, industrial boiler has always been the essential heat source equipment in the production line of chemical products. After a period of investigation, Anda Beituo New Materials Co., Ltd. believed that the thermal efficiency of biomass-fired steam boiler produced by ZOZEN is superior to that of similar products. At the same time, considering the enterprise strength of ZOZEN with high-quality and sufficient-output boiler products, Anda Beituo New Materials Co., Ltd. decided to purchase ZOZEN SZL series biomass-fired steam boiler as the heat source support for its production line.
Considering the expansion of company business and actual demands of production line, Zhengzhou Yisheng decided to introduce the highly-efficient and eco-friendly WNS series gas-fired steam boiler produced by ZOZEN to both improve product quality and cut production cost. Starting from the source of production line, the company intended to get higher economic benefits and achieve the goal of environmental protection.
A safe and high-efficient thermal oil heater is very important to an enterprise, which directly affects the product quality and the economic benefits. In November 2017, the burst of the pipeline of the existing thermal oil heater triggered a fire at Jiangxi Huachen Spice Chemical Co., Ltd. The fire caused considerable losses to the enterprise. Immediately, the leadership of the enterprise decided to repurchase a set of high-quality thermal oil boiler. With good market reputation and strong company strength, ZOZEN got the trust of Huachen Spice. ZOZEN YQW series gas-fired thermal-oil heater has excellent safety performance. The functions of over-temperature alarm, low oil level alarm and over-pressure alarm can ensure the stable operation of the heater. In addition, because the inner coil of the radiant section of the heater absorbs much more heat than the middle and outer rings, ZOZEN designed a large flow rate inner coil to ensure the safe and reliable operation at high temperature.
As a leading manufacturer of the industrial boiler industry, ZOZEN became the boiler supplier of Jinshan Mining with advantages of SZL series biomass-fired boilers in thermal efficiency and environmental protection. This series of boiler adopts double steam drums, and the combustion chamber is surrounded by membrane wall. Meanwhile, the boiler adopts a chain grate. Segmented wind bunkers and wind regulating devices are arranged on the lower part of the boiler to achieve precise air distribution and ensure full combustion of fuel. The thermal efficiency can reach over 88%, and all indicators have reached the international advanced level.
Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler adds a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to level 1 national energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m３. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.
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.
