ZOZEN has been a leading industrial manufacturer after more than 30 years of development. In recent years, with the increasingly strict environmental protection policies, ZOZEN has intensified great efforts in the research and development of gas-fired boiler products and improving the environmental performance and overall thermal efficiency of boilers. As a star product of ZOZEN environment-friendly boiler, the WNS series gas-fired boiler adopts an advanced low NOx burner. In addition, ZOZEN optimizes the design of furnace size, volumetric heat load, and the flue gas flow rate of the convection area to ensure that the NOx emission is less than 30mg / Nm3. In terms of improving the thermal efficiency of the boiler, ZOZEN adopts threaded smoke tubes to enhance the heat transfer effect. Meanwhile, through the application of condensation technology, the sensible and latent heat in the high-temperature flue gas can be fully absorbed, which can increase the inlet temperature and improve the
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.
In the building material industry, the aerated concrete block is a new type of lightweight building material. With good thermal insulation properties and strong sound absorption effects, this kind of material has a broad market prospect. However, the formation of this porous lightweight aerated concrete block requires saturated steam. So, the steam boiler is very important for the production line. With advantages of energy saving and high efficiency, ZOZEN SZS series gas-fired boiler is preferred by the building material industry. The capacity ranges from 2-160t/h, and the working pressure is 1.25-5.3Mpa. This series of boiler adopts a large-volume combustion chamber. An automatic energy-saving burner is equipped to ensure the complete combustion of fuel and improve combustion efficiency. Meanwhile, the combustion chamber uses a narrow-pitch membrane wall, which has good air tightness, to reduce heat loss and improve combustion efficiency. In addition, the boiler adopts an explosion-pr
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.
Saturated steam is mainly used for heating, refining and disinfecting processes of the vegetable oil production. The vegetable oil industry requires a large amount of steam. With high sanitary requirements, the vegetable oil processing companies set high requirements for the quality of steam. YongYou is a large cereals & oils company integrating grain storage, trading, transit and processing. According to the characteristics of high steam pressure, high quality requirements and large load fluctuations in the vegetable oil production process, YongYou purchased two sets of 15 tph biomass-fired steam boilers to meet the requirements of production. In addition, the flexible load adjustment can improve the use efficiency of steam.
The automobile has brought convenience for people's travel. The steam boiler is one piece of the indispensable equipment in the modern automobile production line. As we all know, Geely Auto is one of the top ten enterprises in China's automobile industry. It has achieved rapid development by virtue of its flexible operation mechanism and continuous independent innovation since it entered the field of automobile in 1997. As a first-class manufacturing subsidiary of Geely, Zhejiang Land Rover Automobile Co., ltd decided to expand the Linhai industrial park to produce 300,000 vehicles and key components annually. During the construction of the industrial park, Geely Auto conducted an open bidding and planned to introduce a batch of steam boilers with excellent performance in all aspects.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
