Jilin Longyuan Fertilizer Co., Ltd., founded in 2004, is one of the subsidiaries of Longyuan Group. At present, the company has two ammoniation-granulation compound fertilizer production lines with a total annual output of 500,000 tons, a blended fertilizer production line with an annual output of 300,000 tons, and a potash fertilizer production line with an annual output of 100,000 tons. These high-capacity production lines placed high requirements on the steam quantity and quality of the boiler equipment and also posed a huge challenge to the boiler operating costs, especially the fuel costs. According to the actual demands, ZOZEN customized a set of SZL series coal-fired chain grate steam boiler for Longyuan Fertilizer. This series of boiler has sufficient output, high combustion efficiency and wide fuel adaptability, which can fully meet the needs of Longyuan Fertilizer.
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.
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.
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.
Because of the characteristics of high temperature and low pressure, the thermal oil heater becomes an important piece of equipment of the fine chemical industry. Wuhai Shilian Environmental Protection Technology Co., Ltd. was established in April 2018. With a total investment of 320 million yuan, the company was a reorganization of Wuhai Black Cat Sanxing Fine Chemical Co., Ltd. After sufficient market research and technical demonstration, Wuhai Shilian decided to re-plan the product structure of the original company and invest a 20,000-ton-per-year phenol series technology transformation project including 10,000 tons annual output of resorcinol, which is mainly used for rubber adhesives.
With outstanding product quality and environmental protection performance, ZOZEN has occupied a certain market share in the dyeing and finishing industry and has obtained a good reputation. ZOZEN SZL series biomass-fired boiler is an environment-friendly boiler that is jointly developed by ZOZEN and Shanghai Jiaotong University. According to different characteristics of biomass fuels and different burning rates, ZOZEN rationally arranges the heating area of the furnace arch, furnace wall and furnace to ensure the combustion efficiency and design evaporation. Meanwhile, after numerous experiments, ZOZEN rationally arranges the primary and secondary air, which can effectively reduce NOx emissions and ensure the fuel is fully burned.
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
In the production process of foam packaging materials, the foaming, molding, drying and other technological processes require the stable steam generated by the boiler. Xin'an Baolilong Packaging Co., Ltd. specializes in the production of foam products, mainly used for the packaging of electrical appliances, furniture and a variety of building materials. With the development of the society, the market demand for foam packaging products continues to increase, Baolilong Packaging decided to expand production capacity and introduce a new gas-fired steam boiler. BaolilongPackaging put forward the requirements for the boiler: safety, environmental protection and high efficiency.
