In the carton production process, the steam heating system plays an important role in increasing the temperature of cardboard. With the WNS series gas-fired steam boiler which is high-efficiency, energy-saving, safe and eco-friendly, ZOZEN Boiler has successfully reached the friendly and long-term cooperation with packaging enterprises such as Pacific Millennium Packaging Group and Shengxi Packaging, and has also accumulated abundant project experience. This time, ZOZEN and Chongqing Yongsheng Packaging Co., Ltd. reached the cooperation on the WNS series condensing steam boiler project to provide sufficient and stable steam heat source for the carton and printing production lines.
Changshu Xinda Weft Knitted Fabrics Factory, established in 2003, is mainly engaged in the manufacturing of weft knitted polyester garment accessories, printing and dyeing of textile fabrics, and dyeing processing of loose wools, wool tops and cheeses. Its weft knitted fabrics with good elasticity, extensibility, softness and wrinkle resistance are favored by many customers. In order to meet the increasing market demands, Xinda Weft Knitted Fabrics Factory decided to expand the production and improve the production equipment including supporting heating equipment by purchasing a set of high-efficiency and energy-saving steam boiler. After investigating the boiler products on the market, Xinda Weft Knitted Fabrics Factory finally ordered a set of WNS series three-pass gas-fired steam boiler from ZOZEN Boiler who had completed the delivery recently.
Shijiazhuang Huayuan Mineral Wool Board Co., Ltd. was founded in 2003. Its decorative sound-absorbing mineral wool board is popular and is widely applied in the interior decoration of various buildings such as cinemas, auditoriums, conference halls, etc. There are increasingly higher demands for the sound absorption effects of buildings, which also puts forward higher requirements for the production technology of decorative sound-absorbing mineral wool board. The production of sound-absorbing mineral wool board mainly adopts the wet processing whose dewatering and drying processes require the stable heat source provided by industrial boilers. In order to further improve the product quality, Huayuan Mineral Wool Board decided to introduce a set of ZOZEN YQW series gas/oil-fired thermal oil heater.
In the printing and dyeing industry, industrial boilers have always provided the important heat source support for the printing and dyeing, drying, slashing and other production processes. Jiangsu Zhongcheng Printing and Dyeing Co., Ltd., established in 2001, is mainly engaged in the printing and dyeing of various kinds of cotton and polyester fabrics. Its main products are cotton and linen fabrics, elastic fabrics, high count and high density fabrics. Facing the increasingly strict environmental protection standards, in order to reduce energy consumption and save costs, Zhongcheng Printing and Dyeing decided to upgrade the boiler system and introduce ZOZEN SZS series gas-fired steam boiler to pursue better economic and environmental benefits.
In order to promote the Blue Sky Protection Campaign, Xing County in Shanxi Province has actively implemented the heating project with a focus on promoting the coal-to-gas heating protect in the rural areas of Xing County. This time, ZOZEN Boiler and Xing County Wenxin Thermal Power Co., Ltd. successfully reached the cooperation on the clean and high-efficiency WNS series gas-fired hot water boiler, which strongly promoted the clean heating business in Xing County, improved the local environmental and air quality, and increased the happiness index of the local people.
In the production process of aerated concrete products, the high-temperature steam curing of the aerated concrete body is an important process which can directly affect the product yield. The appropriate temperature for the autoclaved curing of aerated concrete is above 175℃, and the heating equipment includes the autoclave, precuring kiln and so on, which requires the efficient and stable steam boiler to provide heat energy. Anhui Guangrun New Building Materials Co., Ltd. is an enterprise specialized in the production of lightweight autoclaved aerated concrete (ALC) products. In order to improve the production capacity and optimize the production efficiency, Guangrun New Building Materials ordered a set of WNS series three-pass gas-fired steam boiler from ZOZEN Boiler, as the heating equipment in the production of aerated concrete products.
Founded in 2007, Jiangsu Ruisin Metal Products Technology Co., Ltd. mainly produces galvanized steel strip, cold and hot rolled steel strip, and other extended products such as galvanized steel tube, light steel dragon aggregate, cable armoring materials, galvanized steel C, etc., which are widely used in the fields of building materials, photovoltaics, building decoration and agricultural greenhouses. In 2019, Jiangsu Provincial Government introduced the policy to promote the transformation and upgrading of the iron and steel industry and steel enterprises were encouraged to conduct innovations on the manufacturing technology and upgrade the production equipment to realize the intelligent and green manufacturing. In order to actively respond to this policy, Ruisin introduced a set of eco-friendly WNS series three-pass gas-fired steam boiler from ZOZEN Boiler to satisfy the heating demands of the production line and achieve good energy-saving and emission-reduction effects.
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.
