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 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.
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.
In the face of severe environmental problems and the requirements of the Nanjing Air Pollution Control Regulations, Nanjing Golden Dragon Bus Co., Ltd. decided to purchase a set of high-efficient natural gas steam boiler. After numerous investigations, ZOZEN with strong comprehensive strength and good reputation was noticed. ZOZEN is a large industrial boiler manufacturer. The annual capacity of ZOZEN has reached 25, 000 tons of steam. In addition, the high-quality steam of ZOZEN WNS series gas-fired boiler can effectively ensure the quality of the processes of baking and painting of Golden Dragon Bus. Besides, the large-diameter corrugated furnace of this series of boiler not only enhances the flue gas disturbance, but also improves the heat transfer effect. Moreover, several energy-saving devices are equipped at the tail of the boiler to improve the thermal efficiency of the boiler to more than 98%, which can help Golden Dragon Bus to realized the goal of energy saving and emission
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.
Founded in 1818, Libbey Inc. is a large manufacturer of glassware and it is also the standard maker of catering glassware industry in North American. With over 1 billion annual output value, Libbey operates 6 glass manufacturing factories in 5 countries on 3 continents. Libbey (China) Co., Ltd. was set up to develop the Asia-Pacific market. The glass tableware factory located in Langfang Hebei Economic and Technological Development Zone was put into production in early 2007. Its production capacity was up to 100 million per year. As a global company adhering to sustainable development, Libbey decided to update the existing gas-fired boilers to achieve low NOx emissions.
ZOZEN DHL series coal-fired watertube hot water boilers are ideal equipment for central heating. This series of boilers are forced-circulation, single-drum horizontal chain grate hot water boilers. Membrane water walls are arranged around and in the middle of the furnace to absorb the radiant heat of high-temperature flue gas in the furnace. And the large furnace extends the residence time of the flue gas in the furnace, making the fly ash and combustible gas be fully burned, which not only improves the thermal efficiency, but also greatly reduces the amount of fly ash and the original emission concentration of the boiler. The boiler arch adopts the scientific and technological achievements of the Xi'an Jiaotong University's to ensure the combustion effect of inferior coal and expand the coal adaptability. Boiler grate adopts bar grate to improve the operation safety. Through stepless speed regulation, users can adjust the load arbitrarily without affecting the thermal stability of com
Fruit and vegetable juice processing production lines and fruit and vegetable drying production lines are inseparable from the support of sufficient steam heat sources provided by industrial boilers. Yitong Fruit and Vegetable Juice Co., Ltd. was established in 2011, in Xianyang, Shaanxi Province. It is a branch established by Yantai North Andre Juice Co., Ltd. The company can produce 25,000 tons of concentrated juice per year. The products are exported to the United States, Europe and other parts of the world.
