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.
With increasingly stringent environmental protection policies, coal-to-gas boiler projects are progressing in an orderly manner across the country. In this process, ZOZEN WNS series gas-fired steam boiler with excellent environmental performance has been widely recognized and favored by the market. This series of gas-fired boilers adopts a large-diameter corrugated furnace, which can not only ensure the full combustion of the fuel to a certain extent, but also effectively absorb the thermal expansion. And the threaded smoke tubes have good thermal scalability, scientific airflow design, effectively absorb the flame heat, and combined with the energy-saving devices at the end of the flue, the boiler thermal efficiency can reach over 98%. In addition, in response to the low NOx emission requirements put forward by more and more enterprises, ZOZEN has selected international advanced low NOx burners to easily achieve NOx below 30mg/Nm3, and customized a full set of boiler system design sol
In response to national environmental protection policies and initiatives for energy conservation and emission reduction, many printing and dyeing companies have technically reformed coal-fired boilers on their original production line. Among them, Wujiang Lianhua Dyeing and Finishing Co., Ltd. was established in 2002, and has now developed into a large-scale production enterprise integrating weaving, dyeing and finishing, printing and import and export trade.
In the food industry, efficient and energy-saving boiler systems are of vital importance to enterprises and will directly affect their economic benefits. Based on market analysis, Xuanwei Wotu Agricultural Development Co., Ltd. decided to implement a potato deep processing project in Yunnan. As an important piece of heat source equipment for this project, the ZOZEN YLW series thermail fluid heater and matching steam generator ensure a stable and sufficient steam supply for potato deep processing production lines.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
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.
Sihai Dyeing and Finishing knew very well that an energy-efficient boiler can significantly reduce operating costs and improve economic efficiency. After comparing many industrial boiler manufacturers, Sihai Dyeing and Finishing chose ZOZEN as its boiler supplier. The technical advantages and advanced manufacturing processes adopted by ZOZEN have become the powerful guarantee for the high quality of gas-fired boilers, in terms of boiler gas consumption, thermal efficiency and low emission of NOx. In addition, the automatic control system of ZOZEN not only greatly reduced the workload of the boiler operator, but also ensures the safe and stable operation of the boiler.
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.
