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.
ZOZEN WNS series gas-fired hot water boilers are widely used in industries such as central heating, hotels, and hospitals. This series of gas-fired boilers adopts a wetback structure. The large-diameter corrugated furnace can not only effectively absorb the thermal expansion, but also increase the radiant heating area. With the advanced combustion equipment, this series of gas-fired boilerscan ensure the full combustion of the fuel, and the thermal efficiency can reach over 98%. And the WNS series boiler is a package boiler, which is fast to install and saves a lot of installation and capital investment costs. In terms of quality assurance, ZOZEN has established a strict quality management system. Each boiler needs to undergo strict quality inspection procedures to complete the final assembly.
ZOZEN has played an active role in promoting the process of "coal to gas". In particular, the WNS series of gas-fired steam boilers have gained a good reputation in the industry due to their safe and efficient performance. This gas-fired boiler features compact design and is equipped with boiler control, alarm and interlocking devices of water level and steam pressure to ensure safe and reliable boiler operation. And the large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes increase the heating surface. With the energy-saving device at the tail of the flue, the exhaust gas temperature is reduced below 60℃, and the thermal efficiency is as high as 98%, helping clients achieve their goal of energy saving and emission reduction.
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.
Hebei Anguo Modern Traditional Chinese Medicine Industrial Park takes modern Chinese medicine and healthy food as the leading industriies. The industrial clustering advantages and perfect infrastructure conditions have attracted many enterprises such as Tong Ren Tang, Tasly and China National Traditional Chinese Medicine Co., LTD. The concentrated supply of high-quality steam provides sufficient heat for the drying, extraction and stewing of traditional Chinese medicines. Therefore, these enterprises have strict requirements on the performance in various aspects of steam boilers.
ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.
