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.
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.
The Second Hospital of Jilin University is a third-class & first-grade comprehensive clinical hospital. Hot water and steam are essential energy sources for large comprehensive hospitals, providing adequate steam heat energy support for hospital heating and daily disinfection. Under the background of current energy-saving emission reduction and refined management, the Second Hospital of Jilin University actively responded to the national “coal to gas” policy and decided to replace the old boiler equipment with low efficiency and high emission.
Veolia (Harbin) Thermal Power Co., Ltd. was established in 2003 and is a Sino-foreign joint venture controlled by Veolia Group. The company's main business is to supply heat to the southwestern part of Harbin. The current heating area is about 19 million square meters, which ranks the top three in Harbin. In order to ensure the heating effect, Veolia Thermal Power decided to introduce the fully automatic gas-fired hot water boilers featuring environmental protection, ensuring that the boilers meet the needs of centralized heating as well as the flue gas meets the standard discharge.
Steam boilers are the important heat source equipment in the plastics industry, providing sufficient heat for polymerization, dehydration, drying and thermoforming processes. JJS SRL is a Chilean company with more than 40 years of experience, specializing in the production of polyurethane products for a wide range of industries. Temperature is a critical factor in the production of polyurethane products. Generally, the polyurethane reaction temperature is controlled between 60 and 100 degrees. If the temperature is too low, the reaction rate will be very slow, which is not conducive to the reaction. Therefore, the stable operation of steam boilers plays a vital role in the enterprise.
Established in September 2002, Shanghai Flower Port Enterprise Development Co., Ltd. is a large-scale modern flower enterprise integrating professional production, seed research and development, horticultural talent training and urban agriculture sightseeing. In the process of cultivating flowers, the growth environment of constant temperature and humidity is very important. The boiler plays a vital role in maintaining the specific temperature and humidity of the flower greenhouse.
