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 WNS series three-pass condensing gas-fired steam boiler produced by ZOZEN Boiler not only can meet the actual demands of Nanjing Changli's honey production lines, but also can help the enterprise achieve the goal of saving energy, reducing emission and protecting the environment by virtue of its advantages of good performance in safety and efficiency and high degree of automation.
This time, Shanghai High-New Science & Technology Development Co., Ltd. selected the ZOZEN YQW series gas-fired thermal oil heater and supporting waste heat boiler for its project in Ethiopia. To ensure the hot-pressing quality of the wood-based panels, the temperature of the hot-pressing board surface should be as uniform as possible. Therefore, High-New Science & Technology set clear requirements that the oil temperature and operation of the thermal oil heater should be stable. This series of boiler adopts a waste heat boiler to recover high-temperature flue gas. The team generated through the heat exchanges of the waste heat boiler can heat the mill, rubber making machine and other facilities that require steam heat source. The waste heat boiler not only further improves the fuel utilization, but also improves the overall thermal efficiency of the heater to more than 95% and reduces the operation costs. In addition, many advanced facilities independently developed by ZOZEN provide a
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
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.
Saturated steam is mainly used for heating, refining and disinfecting processes of the vegetable oil production. The vegetable oil industry requires a large amount of steam. With high sanitary requirements, the vegetable oil processing companies set high requirements for the quality of steam. YongYou is a large cereals & oils company integrating grain storage, trading, transit and processing. According to the characteristics of high steam pressure, high quality requirements and large load fluctuations in the vegetable oil production process, YongYou purchased two sets of 15 tph biomass-fired steam boilers to meet the requirements of production. In addition, the flexible load adjustment can improve the use efficiency of steam.
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.
The dyeing auxiliary is a chemical which enables a processing operation in textile preparation, dyeing, printing or finishing to be carried out more effectively, a boiler provides stable heat source for its production process. Wuxi Kailai Biotechnology Co., Ltd., established in 2001, is an enterprise specializing in developing and manufacturing textile dyeing auxiliaries. The improving performance requirements for textiles lead to a largely increasing demand for dyeing auxiliaries. Kailai Biotechnology decided to obsolete the backward productivity due to the need of enterprise's own development as well as complying with the policy requirements of environmental protection, Kailai Biotechnology planned to order one set of 1.8 million Kcal thermal oil heater and use clean energy natural gas as boiler fuel.
As one piece of important equipment of the production line, the thermal oil heater has a direct impact on the quality of dyeing auxiliaries and the benefit of the whole enterprise.
