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.
The automobile has brought convenience for people's travel. The steam boiler is one piece of the indispensable equipment in the modern automobile production line. As we all know, Geely Auto is one of the top ten enterprises in China's automobile industry. It has achieved rapid development by virtue of its flexible operation mechanism and continuous independent innovation since it entered the field of automobile in 1997. As a first-class manufacturing subsidiary of Geely, Zhejiang Land Rover Automobile Co., ltd decided to expand the Linhai industrial park to produce 300,000 vehicles and key components annually. During the construction of the industrial park, Geely Auto conducted an open bidding and planned to introduce a batch of steam boilers with excellent performance in all aspects.
For a long time, steam boilers have played an indispensable and important role in the production lines of various feed enterprises. Established in 1996, Guangdong Yuanxin Feed Industry Co., Ltd. is a company integrating R & D, production and sales of livestock, poultry, aquatic products and bullfrog feed. With the rapid development in recent years, the market share of Yuanxin Feed has continued to expand, and the company needed to purchase new steam boilers to meet the actual needs of the production line. Based on the mutual understanding and trust, Yuanxin Feed purchased boiler equipment again from ZOZEN on the SZL series chain grate steam boiler.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
SZL series steam boiler is a longitudinal double-drum chain grate water tube boiler designed by ZOZEN on the basis of advanced international technology and its own experience. 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. the combustion air system (base) adopts independent compartment and scientific sealing structure; reasonable air conditioning device improves combustion efficiency. The water membrane wall, the front and rear arches and the hearth constitute the boiler furnace, A bank of return convection tube bundles are arranged at the rear of the boiler body to sufficiently absorb the heat released by the combustion. The SZL series chain grate steam boiler system customized by ZOZEN has excellent performance and the thermal efficiency is more than 5% higher than the similar boiler system on the market.
Steam boilers are the important heat source equipment in the plastics industry, providing sufficient heat for polymerization, dehydration, drying and thermoforming processes. JJS SRL is a Chilean company with more than 40 years of experience, specializing in the production of polyurethane products for a wide range of industries. Temperature is a critical factor in the production of polyurethane products. Generally, the polyurethane reaction temperature is controlled between 60 and 100 degrees. If the temperature is too low, the reaction rate will be very slow, which is not conducive to the reaction. Therefore, the stable operation of steam boilers plays a vital role in the enterprise.
In the pharmaceutical industry, a large amount of steam generated by boilers is required to sterilize the instruments and equipment at a high temperature, and the heat source provided by the boiler is inseparable in the processes of drying and cooling of the drugs, tableting and granulating. Zhengzhou Lingkong Biomedical Park has established a service support system covering innovative research and development and mass production of pharmaceutical companies. It is an innovation and entrepreneurship base for life science and biotechnology research and development in Henan Province.
Founded in 1991, Sichuan Liji Pickles & Flavouring Co., Ltd. is a large-scale agricultural and sideline products processing enterprise mainly engaged in the production of pickles, seasonings and red oil series dishes. In order to greatly improve production efficiency and effectively guarantee the stability of product quality, Liji Pickles & Flavouring introduced a series of automated production lines. The boiler is one of the important equipment in its automated production line. The sterilization and disinfection processes during the processing require the steam provided by the boiler.
