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
Central heating is one of the infrastructures of modern cities and an important facility for urban public utilities. According to analyze the purpose of Taoshan Heilongjiang Forestry Bureau that regional central heating, ZOZEN boiler provided a SHX series circulating fluided bed hot water boiler for them. This type of boiler is widely used in the field of central heating for people’s life, has wide fuel adaptability and high combustion efficiency. The exhaust ash has good activity and is easy to be comprehensive utilized without secondary ash residue pollution. The principal said that since coal in the northeast region is dominated by poor calorific coal with low calorific value, this type of hot water boiler just makes use od this, and it can play a role in environmental protection, energy conservation.
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.
Harbin Pharmaceutical Group Pharmaceutical Factory is a key antibiotic production base in China and a national large-scale pharmaceutical company. Pharmaceutical production companies cannot do without steam boilers. Nowadays, haze weather is serious and the country has strict standards for boiler emissions. When selecting the boiler, Harbin Pharmaceutical Group chose the SZW series of coal-fired steam boiler with compact structure and reasonable layout. This type of boiler has large water capacity and strong load adaptability. It is burned in a mechanized grate and burns in layers. It has good fuel combustion effect and high thermal efficiency. The product technology, performance, environmental protection indicators of ZOZEN boiler have reached the international advanced level. The person in charge of the company stated that the products of ZOZEN boiler provide practical and effective solutions for the environmental protection issues in the pharmaceutical industry.
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
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
Zhejiang Huadi Textile Printing & Dyeing Co., Ltd. is a professional home textile dyeing and printing company. It covers an area of 140,000 square meters, a total construction area of 160,000 square meters, under the chemical fiber dyeing, printing, cotton dyeing, printing, knitting dyeing, printing three plants, owns first-class dyeing printing equipment in the world introduced from Italy, Germany, Austria, Switzerland, South Korea and other countries, aims to create a first-class home textile fabric processing base. The high energy consumption processes such as water washing, dyeing, printing, and post-finishing required for the production of Zhejiang Huadi textile printing and dyeing enterprises need to be carried out at high temperatures. The thermal oil heater is an indispensable heat source device in the process. As the company's previous related equipment has not reached the ever-growing production demand, the YY (Q) W-4600Y (Q) horizontal gas-fired thermal oil heater produc
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
