Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler adds a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to level 1 national energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m３. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.
In the process of garment printing and dyeing, heat setting, dyeing, drying and other processes require a stable steam heat source provided by the boiler. Chongqing No.3533 Printing and Dyeing and Clothing Co., Ltd. is a large-scale printing and dyeing base in southwestern China. Its products sell well all over the world and meet the needs of foreign military needs such as Britain, Italy, the United States, Spain, etc.
Steam boilers are used to provide steam in bleaching, concentration, drying and other production process of paper industry. Thai Development Industrial Paper Co. Ltd is one of large paper mill in Thailand, producing pulp, mechanical pulp, paper, board. Steam is an essential element in their production process. With the expansion of business and scale, the paper mill's demand for steam is increased by years. Therefore, Thai Development Industrial Paper Co. Ltd needs to order several sets of new steam boilers. Coal is used to be the boiler fuel in this paper mill so that they pay great attention to the combustion efficiency. After knowing their actual situation, ZOZEN’s sales manager has supplied 15tph SZL series water tube steam boilers for the company. This series of steam boiler is adaptable for all kinds of coal. Unique chain grate produced by ZOZEN is adopted for the fuel to be fully burned. Meanwhile, rational air register is designed to improve combustion efficiency.
Coal-fired water tube boilers play an important role in the process of dyeing, steaming and printing in apparel industry. Worldon (Vietnam) co., Ltd is one of famous garment factory invested by Shenzhou International. It produces high-end apparel for brands such as ADIDAS, PUMA, UNIQLO, NIKE, etc.. In order to meet need of the market, ordering a new steam boiler with high efficiency and stable running is of vital importance to Worldon. In 2015, Worldon (Vietnam) co., Ltd had partnered with ZOZEN, ordering two sets of coal-fired water tube boilers. After 3 years’ stable running, ZOZEN’s coal-fired water tube boilers are proved that the fuel can be fully burned and thermal efficiency can reach above 98%. Therefore, ZOZEN is preferred by Worldon, providing them with a coal-fired water tube boiler this time.
Jiangxi Gannan Tobacco Leaf Compounding Co., Ltd. is a large state-owned enterprise. During 2010, the registered capital of Jiangxi Gannan Tobacco Leaf Refining Company registered a capital of 450 million yuan, and implemented a process technology upgrade and transformation project—the transformation of auxiliary equipment for the process of threshing and roasting. Due to the frequent use of steam during the production of the threshing and roasting, the company meets the demand for the process of tobacco moistening, wetting and re-roasting. In accordance with the actual demand of the project, Jiangxi Gannan Tobacco Recycling Company purchased a 15-ton coal-fired steam boiler with an assembled structure at ZOZEN boiler. The boiler is a horizontal steam boiler with double drums vertical installation chain furnace drain designed by ZOZEN boiler technical personnel, according to domestic and foreign advanced technology. The installation of the equipment is convenient at the site and the pe
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
PT.Lontar Papyrus has built their pulp mill in Sumatra island since 1994.
During manufacture, the raw material needs to be cut, grinded and cooked, as per the capacity rising, the huge power and steam consumption makes the manufacturing cost higher and higher. For making their product more competitive, PT.Lontar Papyrus decided to build their own cogeneration energy plant, high-quality steam is used for making electricity and low-quality steam is used for process. Cogeneration boiler has high requirement for steam quality, pressure, and boiler smooth running. Because it needs to be installed on-site, it also requires the supplier to be profession for on-site installation. After many times visit and discuss, PT.Lontar Papyrus chose ZOZEN coal-fired steam boiler, by cooperating with local agent, ZOZEN full filled this big project successfully. The boiler has been running well and each target are reached too.
The rubber production of the outer layer of the wire and cable must undergo a vulcanization process, and the vulcanization process need the steam from boilers to heat and pressure the rubber. Anhui Cable is an enterprise specializing in the production of wire and cable. It mainly produces and operates 1E class K2, K3 and non-1E medium voltage power cables, various types of flame retardant and refractory special cables. In 2015, the principal of Anhui Cable purchased a 4-ton SZS Condensing Gas Fired Boiler in Zozen Boiler to provide steam for rubber vulcanization. The steam temperature was required to be between 140-180℃. After vulcanization, the natural cooling was performed, opened the valve, the steam condensate in the pipeline will go directly into the cooling pool. After steam cooling, fresh water can be added to the processed of drawing, annealing, ,water sealing, extruding, extruding rubber, mixed rubber, desulfurization and dust removal, which saves a lot of production water for
