As the important energy equipment in chemical production, boilers provide heat energy for chemical production processes such as polymerization, drying and dehydration. Navoiyazot is affiliated to the national stock company Uzkimyosanoat (Chemical Industry Holding Company). It mainly produces more than 170 kinds of mineral fertilizers and chemical reagents. Its production capacity covers more than 30% of Uzbekistan's total chemical production, being a leading company in the Uzbekistan chemical industry.
In the manufacturing process of all kinds of chemical auxiliaries, the key process of concentration needs steam support produced by steam boilers, which direct affect the quality and performance of chemical auxiliaries. Jiangsu Han Kuang Industrial Co., Ltd. has become one of the national largest production bases of petrochemical auxiliaries. With a sudden increase in market demands, Han Kuang Industrial decided to introduce a branch of equipment that equipped with automation systems to accelerate the intelligent transformation of environmental protection and safety. Han Kuang Industrial planned to purchase environmental friendly and high efficient steam boilers featuring automatic and safe operation. After a series of careful and rigorous market research, Han Kuang Industrial reached cooperation intention with ZOZEN and ordered 2 sets of 4 tph WNS series condensing gas-fired boilers (WNS4-1.6-Q). The full automatic intelligent control ensures the long-time safe and stable operation o
Yuanda Cable Co., Ltd.---a high-tech company specializing in the research, product and sale of power cables, branch cables and computer cables. The cable manufacturing process includes three processes of mixing, extruding and vulcanizing. During the extrusion process, overheating easily leads to scorching, when the temperature is too low, it’s hard to gel. In the vulcanization process, bubbles are easily generated when the temperature is too low or too high. The temperature and pressure requirements of every process are different, so the control of cooking temperature and pressure must be precise and adjustable. In 2011, Yuanda Cable had customized a 4-ton DZL coal-fired steam boiler at ZOZEN. This series carried out comprehensive safety monitoring of the boiler’s water level and steam pressure, and it used boiler safety control technology that complied with EU coal-fired boiler standards to ensure boiler operates safer and more reliable. The automatic and interlocking control technolo
Liyang Rhodia Fangzheng Rare Earth New Material Co., Ltd. is a company formed by Liyang Rare Earth General Plant, Peking University Fangzheng Group, and French Rhodia Electronic and Catalyst Materials Company. The company covers an area of 126,000 square meters, with total assets of 450 million yuan. It has light, medium and heavy rare earth separation production lines. It separates 15,000 tons of rare earth minerals and ranks first in the country. It is a national high-tech industry. In 2017, Liyang Rhodia Fangzheng Rare Earth New Material Co., Ltd. has learned from many comparisons and purchased a WNS 10-ton condensing gas-fired steam boiler from our company. ZOZEN WNS series condensing gas-fired steam boilers have high operating efficiency, sufficient output, easy operation and maintenance and environmental. They are your ideal boiler products.
China Tobacco Shiweice(Yunnan) Reconstituted Tobacco Co., Ltd. mainly targets the Chinese cigarette market. Due to the need of production development, China Tobacco Shiweice adopts the most advanced papermaking method to reconstitute the tobacco leaf production process. Remanufactured tobacco needs a large amount of steam in production. The previous boiler supply cannot meet the demand for new production processes. After the natural gas direct supply pipeline project was completed, China Tobacco Shiweize ordered a 20-ton gas-fired steam boiler with natural gas as fuel in the ZOZEN boiler through a bidding exercise. The body and hearth of the series boilers are surrounded by membrane-type water-cooled walls, and use micro-positive pressure combustion, there is no cross-talk problem, the operating environment without pollution.
As the determination of country to prevent and control air pollution is increasing, various policies have been introduced across the country. Almost every region, the time period and number of boiler renovations have been issued. In order to maximize the cost savings of the company’s operations, most companies will choose to convert coal-fired boilers to gas-fired boilers, and the rubber chemicals industry is no exception. With the increasingly stringent policies and regulations being promulgated in succession, in 2013, Huasheng rubber planning rubber auxiliary energy-saving renovation project, they purchased a 10-ton WNS condensing gas-fired steam boiler at ZOZEN boiler. The condensing boiler is a hull-type three-way pyrotechnic tube structure researched and developed based on the mature technology of the current gas boiler, the heat load of the boiler is low. An additional condenser is installed at the tail of the flue to increase the boiler inlet temperature and reduce the temperatu
The gas-fired replace coal-fired heating project is one of the decontamination projects to improve air quality in Tianjin. As a result, the fifth gas-fired replace coal-fired boilers project in Tianjin city center ware launched.
First, the coal-to-gas conversion project of the Tiantuo Heat Source Plant in Nankai District. The Tiantuo plant is surrounded by empty land to be built. The project plans to dismantle the original 3 sets of 58MW, 2 sets of 29MW coal-fired hot water boilers and 3 sets of 14 MW steam boilers. They build a new gas-fired boiler room on the west side of the existing boiler room, and install 10 sets of 29MW gas-fired boilers with auxiliary equipment, the heating area is maintained at 3.5 million square meters. Through vigorous bidding campaigns, ZOZEN provided 5 sets of 29MW gas-fired hot water boilers (SZS-1.6/130/70-Q) for the Tiantuo Heating Plant with advanced technology and strength in the boiler industry.
Second, Hedong District also undertakes the task of
Luoyang Junshan Pharmaceutical Co., Ltd. is a modern pharmaceutical company mainly engaged in traditional Chinese medicine and natural medicine, integrating R&D, production, and sales. Traditional Chinese medicine pharmaceutical companies generally have extraction, concentration, distillation, drying, sterilization, purified water preparation, air-conditioning chillers and other technological equipment, all of which use steam as a heat source. However, at this stage, the general TCM companies do not use steam for comprehensive utilization. Steam is used only once, and a large amount of waste heat and waste heat are directly discharged into the atmosphere. The overall energy utilization rate is low. The person in charge of Junshan Pharmaceutical, through investigating and comparing the boilers on the market, finally chose to customize a 6-ton WNS condensing gas-fired steam boiler in the Zozen boiler to reduce boiler steam consumption and waste heat recovery, and increase the boiler ther
