With a large flow of tourists, Zhengzhou Railway Station is one of the eight transportation hubs in China. It is known as the heart of Chinese railways. The comfortable waiting environment comes from stable heating system. It is Zhengzhou Heating Company Second Road Heat Source Factory that provides stable heat source for Zhengzhou Railway station. Founded in 1989, the heat source factory was put into operation in 1992. In recent years, with the aging of old boilers, the thermal efficiency of the existing 4 sets of 20 tph chain grate steam boilers has been gradually reduced. Besides, considering environmental protection and other factors, Second Road Heat Source Factory decided to implement the Coal-to-Gas Project, dismantle the existing low-efficiency and high-consumption coal-fired boilers, and introduce some sets of SZS series gas-fired steam boilers.
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.
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
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.
In the manufacturing process of all kinds of chemical auxiliaries, the key process of concentration needs steam support produced by steam boilers, which direct affect the quality and performance of chemical auxiliaries. Jiangsu Han Kuang Industrial Co., Ltd. has become one of the national largest production bases of petrochemical auxiliaries. With a sudden increase in market demands, Han Kuang Industrial decided to introduce a branch of equipment that equipped with automation systems to accelerate the intelligent transformation of environmental protection and safety. Han Kuang Industrial planned to purchase environmental friendly and high efficient steam boilers featuring automatic and safe operation. After a series of careful and rigorous market research, Han Kuang Industrial reached cooperation intention with ZOZEN and ordered 2 sets of 4 tph WNS series condensing gas-fired boilers (WNS4-1.6-Q). The full automatic intelligent control ensures the long-time safe and stable operation o
The development of technology and the progress of skill require the diversification of the quality of the sodium sulfide. Enterprises must produce different types of sodium sulfide according to different users. Taihua Industry is high-tech chemical enterprise. Its main products are pure benzene, toluene, p-tert-butyl benzoic acid, industrial sodium sulfide, anhydrous crystalline sodium sulfide and nine-hydrate crystalline sodium sulfide. The production of sodium sulfide requires high temperature and stable steam. Therefore, Taihua Industry has conducted an inspection of the same industry manufacturers and combined with actual conditions of the unit to transform the caustic soda production system in the evaporation section. At first, Taihua purchased a 2.4 million thermal oil heater at ZOZEN(YY(Q)W-2800Q) to improve utilization rate of heat energy. Later, in order to increase the coal utilization rate, Taihua purchased a 2.4million kcal thermal oil heater(YLL-2800MA(w)) at ZOZEN
Hebei Ruixin Jinhua New Energy Technology Co., Ltd. invested RMB 320 million in 2015 to build a 100,000-ton/year crude benzene hydrotreating project in two phases; in 2016, it invested RMB 120 million in equipment and manufacturing in District A of Fengfeng Mining Area. "Triazole, piperidone production project." In the early stage of the project, the technical personnel of ZOZEN boiler went to the customer site for field visits to help the customer analyze the equipment occupation area and site space planning. What’s more, the need of steam in the process must be high-temperature and stable. In the end, ZOZEN boiler design a thermal oil heater with a rated thermal power of 20 million kcal to the project for the customer. The boiler adopts ejected forced circulation system, it has a complete control system and safety monitoring device that can accurately control the working temperature and safeguard safety operation.
