In order to improve the production process, Jiangxi Hetian New Energy Technology Co., Ltd. selected ZOZEN as its heat source equipment supplier. With outstanding energy-saving performance, the WNS series gas-fired boiler provided stable steam heat source support for the production of batteries. This series of boiler adopts the wetback structure. The large-diameter corrugated furnace not only effectively absorbs thermal expansion, but also has sufficient steam storage space and heating area. At the same time, ZOZEN customized the boiler according to the requirement of the user. The boiler adopted a two-pass design. The economizer and condenser were equipped at the end of the flue, which could make full use of the waste heat to increase the boiler inlet temperature, improve the boiler thermal efficiency to more than 98% and save costs for users. It is worth mentioning that ZOZEN not only has advanced production technologies, but also has professional and perfect services.
This time, Shanghai High-New Science & Technology Development Co., Ltd. selected the ZOZEN YQW series gas-fired thermal oil heater and supporting waste heat boiler for its project in Ethiopia. To ensure the hot-pressing quality of the wood-based panels, the temperature of the hot-pressing board surface should be as uniform as possible. Therefore, High-New Science & Technology set clear requirements that the oil temperature and operation of the thermal oil heater should be stable. This series of boiler adopts a waste heat boiler to recover high-temperature flue gas. The team generated through the heat exchanges of the waste heat boiler can heat the mill, rubber making machine and other facilities that require steam heat source. The waste heat boiler not only further improves the fuel utilization, but also improves the overall thermal efficiency of the heater to more than 95% and reduces the operation costs. In addition, many advanced facilities independently developed by ZOZEN provide a
After having an in-depth understanding about the industrial boiler market, Yushuwan Coal Mine selected ZOZEN as its boiler equipment supplier. ZOZEN provided a scientific and reasonable boiler solution for Yushuwan Coal Mine including multiple sets of gas-fired steam boilers. The boiler solution not only can meet the requirements of production and living, but also can improve the utilization rate of thermal energy. Meanwhile, every ZOZEN gas-fired boiler adopts a low NOx burner to meet the low NOx emission requirement. In addition, the utilization of staged combustion technology greatly reduces the generation of NOx. And, the flue gas NOx content showed in the third-party EIA test is 14-17mg/m3. The value is far lower than the environmental protection standard of 30mg/m3.
Jiangsu Hengtong Printing and Dyeing Group Co., Ltd. set high requirement for the automatic operation and safety of the thermal oil heater which had great importance to its production line. After rigorous market research, Hengtong purchased a set of ZOZEN YQW series gas-fired thermal oil boiler in 2018. Equipped with an advanced burner, this series of boiler can realize fully automatic operation, including automatic combustion, automatic adjustment of the liquid level of the expansion tank, outlet temperature, flow rate and automatic protection. Meanwhile, the PlC control system is easy to operate. Various kinds of settings can be completed through the intelligent man-machine interface. In addition, the boiler has been in stable and high-efficient running since its operation, which was highly praised by Hengtong. This time, with the expansion of the production scale, Hengtong planned to get another thermal oil heater and cooperate with ZOZEN again.
With the expansion of business, XinYi Textile introduced the ZOZEN DZL series of biomass-fired boiler. This series of steam boiler is a horizontal chain grate boiler. It has excellent safety performance. The extremely low water level electrode can effectively prevent boiler water shortage accidents caused by extremely low water level operation in manual mode and strengthen the safety protection of water level control. Meanwhile, when the system pressure exceeds the specified value, the full lift spring-loaded safety valve will be automatically opened to release pressure, which can avoid the accidents caused by excessive pressure. In addition,the chain grates of this series of boiler are all manufactured by ZOZEN. A 72-hours test run of the chain grates can ensure the moderate tightness of the grate. Besides, the scientific grate arch design, reasonable air distribution and governor box speed ensure the full combustion of biomass pellet fuel and the overall thermal efficiency of the boi
Known as "mirror of the sky", the Uyuni Salt Flat of Bolivia is a salt flat with the largest lithium reserves in the world. It is estimated that the lithium reserves of the Uyuni Salt Flat account for 70% of the lithium reserves of the world. The lithium industry chain market has huge potential and the abundant lithium resources also provide favorable conditions for Bolivia's economic development. To effectively promote the exploitation and utilization of the lithium resources of the salt flat, Yacimientos de Litio Bolivianos-YLB, a state-owned listed company of Bolivia, decided to build a new lithium carbonate plant. As an important piece of supporting equipment, the industrial boiler will provide a reliable heat source for the development and commercialization of the resources of the salt flat.
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.
This time, Jilin Deda purchased a branch of ZOZEN WNS series gas-fired boilers for demands of meat production and workers' heat supply. This type of gas-fired steam boilers adopts horizontal internal combustion wetback structure with novel design and rational structure. The burner flame is burning in large-diameter corrugated furnace in slight positive vacuum condition. It combined with high-efficient threaded smoke tubes and scientific furnace heat preservation design that can effectively improve thermal efficiency to more than 98%, which is superior to the national Level 1 energy efficiency standard and can realize the expected energy-saving goal of Jilin Deda. Besides, the advanced automatic control system can realize automatic start-stop, load adjustment, water supply and other operations according to the demands of users. With features of easy operation and low failure rate, the control system is both safe and reliable.
