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.
In the face of severe environmental problems and the requirements of the Nanjing Air Pollution Control Regulations, Nanjing Golden Dragon Bus Co., Ltd. decided to purchase a set of high-efficient natural gas steam boiler. After numerous investigations, ZOZEN with strong comprehensive strength and good reputation was noticed. ZOZEN is a large industrial boiler manufacturer. The annual capacity of ZOZEN has reached 25, 000 tons of steam. In addition, the high-quality steam of ZOZEN WNS series gas-fired boiler can effectively ensure the quality of the processes of baking and painting of Golden Dragon Bus. Besides, the large-diameter corrugated furnace of this series of boiler not only enhances the flue gas disturbance, but also improves the heat transfer effect. Moreover, several energy-saving devices are equipped at the tail of the boiler to improve the thermal efficiency of the boiler to more than 98%, which can help Golden Dragon Bus to realized the goal of energy saving and emission
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.
Among many industrial boiler products, Bintou Thermal Power selected ZOZEN SZS series gas-fired steam boiler for peak shaving. This series of boiler is designed with longitudinal double drums and " D " type chamber structure. The combustion chamber adopts a membrane wall structure, which has good air tightness, no smoke leakage, and high thermal efficiency. Meanwhile, the tail of the boiler is equipped with flue gas condensation recovery devices to effectively control the exhaust temperature and increase the thermal efficiency to more than 98%. In addition, devices such as explosion-proof doors, flame detectors, water level alarms and water level interlocks are equipped to further ensure the safety of boiler operation.
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.
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.
This series of thermal oil heater can realize low-pressure and high-temperature heating by utilizing the characteristics of the thermal oil heater. The high thermal inertia can effectively maintain the temperature uniformity during the food heating process. This thermal oil heater has outstanding energy-saving effects and low operation costs. It adopts closed-loop circulating liquid phase to transfer heat energy, the heat loss of steam boilers such as heat running, dripping and leaking can be avoided. Meanwhile, a complete operation control system and safety monitoring devices are equipped to precisely control the working temperature. It was the mix of these advantages that effectively reduced the production costs and improved the production safety of Changling Food.
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.
