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.
China CEC Engineering Corporation is a large-scale engineering consulting and design company. Its main business covers engineering design, consulting, supervision and general contracting. It provides services for pulp and paper, energy and environmental protection, salt manufacturing and salt chemical engineering, household appliances, food, construction, municipal and other industries. In order to meet the demands of the project to construct a comprehensive PVC resin production plant with an annual output of 60,000 tons in Mekele, Ethiopia, CEC finally chose ZOZEN boiler as the boiler supplier for this project based on the investigation on the domestic boiler market. This time, CEC purchased 3 sets of SZL series coal-fired chain grate water tube steam boiler form ZOZEN Boiler who had completed the shipment recently.
Wuxi Guotai Color Printing Co., Ltd., established in 1958, mainly engages in the production and sales of printing and flexible plastic packaging products. At present, the company is committed to developing and producing the flexible plastic packaging products in the agrochemical field with several compound production lines for printing, which can meet the demands for protective packaging in the agrochemical, daily use chemical, food, medicine and other fields. In order to further improve the production capacity and achieve higher economic benefits, Wuxi Guotai Color Printing Co., Ltd. ordered a set of WNS series gas-fired and oil-fired three-pass condensing steam boiler from ZOZEN Boiler. This type of boiler has the characteristics of sufficient output, high thermal efficiency and small occupied area to help the enterprise save a lot of fuel costs and basic construction costs.
Weifang Huabao Textile Co., Ltd., founded in 2004, is jointly invested by Changyi Huabao Textile Co., Ltd. and Hong Kong Aosen International Co., Ltd., which mainly engages in the weaving, dyeing and finishing of high-end fabrics. The steaming and drying processes of dyeing and finishing need a continuous and stable heat source. The huge heat energy consumption puts forward higher requirements for the industrial boiler equipment. Therefore, after careful consideration, Weifang Huabao Textile decided to introduce two sets of YQW series gas-fired thermal oil heater from ZOZEN Boiler, which helped the company successfully compete the "coal to gas" project, greatly reduce the energy consumption and further realize the green and sustainable development.
The high-temperature steam is essential for the production process of concentrated juice, so the steam boiler has always played an important role in the production line of concentrated juice. The stability and quality of steam generated by steam boiler have a direct effect on the purity and yield of concentrated juice. Yantai North Andre Juice Co., Ltd., founded in April of 2002, specializes in the production and sales of fruit and vegetable juice products. As one of the eight concentrated juice processing bases of Yantai North Andre Juice Co., Longkou production base decided to introduce the high-performance industrial boiler equipment in order to further improve the processing capacity of fruit and vegetable juice and reduce energy consumption in the production process.
Anda Beituo New Materials Co., Ltd., founded in 2017, is a professional environmental protection engineering enterprise specialized in the development, design, production, sales and services of environment-friendly products. As is known to all, industrial boiler has always been the essential heat source equipment in the production line of chemical products. After a period of investigation, Anda Beituo New Materials Co., Ltd. believed that the thermal efficiency of biomass-fired steam boiler produced by ZOZEN is superior to that of similar products. At the same time, considering the enterprise strength of ZOZEN with high-quality and sufficient-output boiler products, Anda Beituo New Materials Co., Ltd. decided to purchase ZOZEN SZL series biomass-fired steam boiler as the heat source support for its production line.
There were abundant oil resources in Venezuela, so Inversiones Goa 7 C.A intended to use light diesel oil as the fuel of boiler to reduce the operating costs of enterprise. Light diesel oil was featured with low viscosity, good fluidity and few content of heavy metal and sulfur, whose combustion has low pollution to the environment. What's more, light diesel oil had no need to be heated in the process of transportation and atomization, so direct ignition could be used to start the boiler. In this case, ZOZEN Boiler customized the WNS series light diesel oil fired boiler system solution for Inversiones Goa 7 C.A with advantages of sufficient capacity, easy installation and maintenance, convenient operation and so on.
Considering the expansion of company business and actual demands of production line, Zhengzhou Yisheng decided to introduce the highly-efficient and eco-friendly WNS series gas-fired steam boiler produced by ZOZEN to both improve product quality and cut production cost. Starting from the source of production line, the company intended to get higher economic benefits and achieve the goal of environmental protection.
