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
The 154th Central Hospital of the Chinese People's Liberation Army is a tertiary hospital that integrates medical treatment, teaching, and research. With the continuous expansion of the hospital scale, the increase in the number of beds, departments, and trainees, the boiler evaporation capacity of the original boiler room is too small to meet the sterilization and disinfection, sanitary hot water preparation, hospital laundry and so on. In 2012, the 154th hospital changed its boilers and ordered a 10-ton SZL coal-fired steam boiler for use in the hospital. In recent years, under the increasingly severe atmosphere situation of the whole country and the province, environmental problems have become increasingly prominent. Xinyang has issued the “Implementation Plan for Suppressing Coal-fired Boilers in Xinyang City from 2014 to 2017”. In 2016, the No.154 Hospital as a national tertiary general hospital, actively responded to the call for environmental protection, and implemented replacem
Jiangxi Copper Group is an ultra-large joint enterprise containing copper mining, selection, smelting in Chinese non-ferrous metals industry. It is also Chinese largest copper product production base and an important raw material for sulfide, and gold, silver and scattered metal producing area. As we all know, in the copper smelting process, a large amount of electricity and steam are consumed, and steam consumption accounts for about 30 to 40% of them. ZOZEN boiler has provided two 40-ton SZS condensing gas-fired boilers. The boiler adopts a D-type full-membrane wall structure, and the combustion chamber uses a narrow-pitch tube-type water wall, which has good sealing properties and reduces heat loss. The boiler body is made of high-quality aluminum silicate fiber and then kept in fire-resistant mud to keep the furnace temperature below 45°C and effectively control the heat loss.Luoyang Junshan Pharmaceutical Co., Ltd. is a modern pharmaceutical company mainly engaged in traditional C
ZOZEN boiler’s SZS series of condensing gas-fired boilers adopt double-drum ‘D’ type arrangement, whose structure is compact and floor space is small. The furnace adopts membrane wall structure, the seal between the membrane wall and pipes on both sides of the furnace adopts comb plate, to prevent leakage of condensate and gas. The boiler layout heating surface is large enough to design a large space for steam, to ensure that the boiler operates stably. Jiangsu Shangshang Cable Group is a professional manufacturer of wire and cable, focusing on R&D, manufacturing and services of wire and cable products. For the production needs, they want to expand the boiler room. The technical team of ZOZEN boiler has configured two SZS condensing gas-fired boilers, one 10 ton and one 6 ton, according to Shangshang’s boiler room area and the needs of steam during the production process. And ZOZEN’s steam meet the production requirements of the Shangshang cable.
Wandashan Dairy Industry, which is a holding company of Beidahuang Group, is equipped with 65 modern production lines and can produce nearly 200 varieties of milk powder, liquid milk, beverages, soy products, and rice products. The process of preheating, sterilizing, cooling and other processes of fresh milk requires a lot of steam. Because ZOZEN has provided their product into all walks of life and is one of the few boiler companies that holds a Class A boiler manufacturing license, Wandashan Dairy purchased two 20-tonne SZL coal-fired steam boilers at ZOZEN. According to the difference in coal quality and tonnage, independent wind storage can be set up to ensure the burnout of coal. Wandashan Dairy now processes 1 million tons of fresh milk annually.
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
Wuxi kanglong Rubber Products Co. Ltd produces rubber and latex products including gloves etc.. During rubber material manufacture, vulcanization needs heating under 190-220°C, and finally create rubber. if by using steam boiler, the corresponding steam pressure is at least 2.5MPa, this boiler will be much more expensive and the whole system will be more expensive and high request. So thermal oil heater has unique advantage in rubber plant. It can reach high temperature under normal pressure; boiler construction cost is lower than steam boiler. Also, oil transfer heat more stable, it guarantees product can reach accurate temperature, which make process more accurately running. This heater has compact body, it is transport as a whole body, easy to operate. After visiting and technical discussing, customer chose ZOZEN thermal oil heater.
