Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
In order to realize green production and environmental protection effects, Longwang Food decided to purchase the natural gas steam boiler and sets strict requirements for the eco-friendly performance of boiler. After knowing the huge steam demands of Longwang Food's diary and soybean products production lines, ZOZEN Boiler recommended the SZS series gas-fired saturated steam boiler which has sufficiency output, high thermal efficiency and outstanding eco-friendly performance.
With the continuous development of the building materials industry and the increasing environmental awareness of the whole society, many brick factories in China have conducted the production transition. Ledong Changsheng Standard Eco-friendly Brick Co., Ltd., founded in 2011, has grasped the opportunity to engage in the production and sales of new wall materials, eco-friendly bricks, which earns considerable profits for the company. However, the stable operation of the eco-friendly brick production line depends on the steam supply provided by the industrial boiler, and a set of energy-saving and high-efficiency steam boiler can directly affect the quality of eco-friendly bricks and the economic benefits of the enterprise. Therefore, after a specific investigation on the domestic industrial boiler market, Ledong Changsheng Standard Eco-friendly Brick finally chose ZOZEN Boiler as the boiler equipment supplier.
Guodian Shuangyashan Power Generation Co., Ltd., formerly known as Shuangyashan Power Plant, has been committed to thermal power generation, heat power production and supply since it was founded in 1984, which has made great contributions to the electricity and heat supply for surrounding residents and enterprises. In order to actively respond to the national call for energy conservation, consumption reduction and environmental protection, Guodian Shuangyashan Power Generation Co., Ltd. updated and upgraded the production equipment in time, and purchased the energy-saving and efficient SZS series oil-fired superheated steam boiler from ZOZEN Boiler as the power station start-up boiler. It not only provided a reliable guarantee for the start of power station units, but also helped the enterprise contribute to the environmental protection business advocated by the state.
As one of the important paper varieties, household paper is mainly used in people's daily life. Daqing Xinqingxin Paper Co., Ltd., established in 1998, mainly engages in the processing and distribution of household paper. With the rapid development of China's economy and improvement of people's living standards, household paper sales volume of Xinqingxin Paper has significantly increased. In order to better meet the market demands, Xinqingxin Paper decided to expand the tissue production line and introduce a set of highly-efficient and eco-friendly WNS series gas-fired and oil-fired steam boiler from ZOZEN Boiler.
The new process using the ethylene oxide method has low production costs and stable product quality, however, the yield of the ammonification process and the production continuity are the key points in the process. Therefore, Jiangyin Huachang Food Additive Co., Ltd. has set clearly high requirements for the entire boiler system. ZOZEN Boiler tailor-made the design of the YQW+WNS series boiler system project in order to meet the sufficient and continuous heating source support of the food additive production line. Among them, the body of YQW series gas-fired thermal oil heater adopts three-pass round coiled tube structure, with sufficient heating surface, and the energy-saving device installed at the end of the furnace can ensure the thermal efficiency up to 95%. The advanced combustion device can realize low NOx emissions of the entire boiler system, meanwhile ZOZEN Boiler has equipped the automatic control system to ensure the continuous and efficient operation of the heating source
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.
ZOZEN has been implementing the Belt and Road initiative all the time. Qingdao United Zhenye Energy Saving Technology Co., Ltd carried out an in-depth cooperation with Kazakhstan on environmental protection technology of oil fields. ZOZEN provided stable and efficient thermal energy for the project. The first batch of YQW series thermal oil heaters and WNS gas-fired steam boilers has been delivered to Kazakhstan. It indicated that ZOZEN has got the affirmation of users in Kazakhstan again.
