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.
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.
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.
ZOZEN has accumulated a good market reputation in the Fujian industrial boiler market, providing reliable and stable steam heat source guarantee for many textile printing and dyeing enterprises. Among them, ZOZEN WNS series gas-fired steam boiler has the characteristics of durability, high efficiency and low consumption, which greatly reduce the production cost of textile enterprises and effectively improves economic benefits. During the manufacturing stage, ZOZEN advanced automatic production lines ensure the quality of the welding and assembly of the boiler, reduces the assembly stress and prolongs the service life of the boiler. During the installation and commissioning phase, the large-diameter corrugated furnace of the WNS series gas-fired boiler, the threaded flue pipe for enhanced heat transfer, and the condenser added at the end of the flue effectively improve the heat transfer effect and ensure that the overall thermal efficiency of the boiler is over 98%.
For a long time, steam boilers have played an indispensable and important role in the production lines of various feed enterprises. Established in 1996, Guangdong Yuanxin Feed Industry Co., Ltd. is a company integrating R & D, production and sales of livestock, poultry, aquatic products and bullfrog feed. With the rapid development in recent years, the market share of Yuanxin Feed has continued to expand, and the company needed to purchase new steam boilers to meet the actual needs of the production line. Based on the mutual understanding and trust, Yuanxin Feed purchased boiler equipment again from ZOZEN on the SZL series chain grate steam boiler.
Steam boilers are essential in large hospitals, which are used to sterilize and disinfect medical equipment, hospital bed sheets, quilts, etc. and provide steam for washing machines and dryers in hospitals. Nanyang Second General Hospital is a three-level general hospital with more than 2,000 beds and over 80 clinical and medical technology departments. Therefore, the hospital has a large demand for steam. In response to the national green development concept, People's government of Henan province decided to repurchase a gas-fired steam boiler for daily sterilization and disinfection. Serving as a place of healing the wounded and rescuing the dying, the hospital has high requirements for the quality of steam and the stability of boiler operation. The project leader of Nanyang Second General Hospital was attracted by ZOZEN's perfect production line and strict quality supervision after inspecting many well-known boiler plants.
In the corrugated paper processing line of the packaging industry, the steam boiler is an important heating system for increasing the temperature of the paperboard and is one of the essential equipment. Founded in 1995, Fijian Nanan Lianfa Paper Industry Co., LTD. attached great importance to technical input and strictly controlled product quality. At the same time, they knowed thoroughly that the efficiency of boiler operation would directly affect the company's product quality and economic benefits.With the fierce market competition, Lianfa Paper decided to eliminate backward production capacity and introduce high-quality and high-performance environmentally friendly gas-fired steam boilers.
Plenty of steam is needed in the milk powder production process of sterilizing, concentrating and drying; therefore, a stable steam boiler has a direct impact on the milk production quality. Heilongjiang Feihe Dairy Industry Co., LTD., established in 1962, has won the Gold Award of Monde Selection. As hazy weather appears frequently in recent years, air quality issues have aroused great concern of the whole society. The Chinese government has successively launched "coal to gas" and other environ...
