ZOZEN DHL series coal-fired watertube hot water boilers are ideal equipment for central heating. This series of boilers are forced-circulation, single-drum horizontal chain grate hot water boilers. Membrane water walls are arranged around and in the middle of the furnace to absorb the radiant heat of high-temperature flue gas in the furnace. And the large furnace extends the residence time of the flue gas in the furnace, making the fly ash and combustible gas be fully burned, which not only improves the thermal efficiency, but also greatly reduces the amount of fly ash and the original emission concentration of the boiler. The boiler arch adopts the scientific and technological achievements of the Xi'an Jiaotong University's to ensure the combustion effect of inferior coal and expand the coal adaptability. Boiler grate adopts bar grate to improve the operation safety. Through stepless speed regulation, users can adjust the load arbitrarily without affecting the thermal stability of com
Sihai Dyeing and Finishing knew very well that an energy-efficient boiler can significantly reduce operating costs and improve economic efficiency. After comparing many industrial boiler manufacturers, Sihai Dyeing and Finishing chose ZOZEN as its boiler supplier. The technical advantages and advanced manufacturing processes adopted by ZOZEN have become the powerful guarantee for the high quality of gas-fired boilers, in terms of boiler gas consumption, thermal efficiency and low emission of NOx. In addition, the automatic control system of ZOZEN not only greatly reduced the workload of the boiler operator, but also ensures the safe and stable operation of the boiler.
Sichuan New Torch Chemical Co., Ltd. is mainly engaged in the research and development of hydrogen isotope products, providing safe, stable and high-quality products such as heavy water, deuterium generation reagents and high-purity hydrogen sulfide to the national defense cause. The production process of these chemical products is inseparable from the steam heat source provided by the boiler, which is one of the main power equipment on its production line.
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.
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
Shandong Luhua Group Co., Ltd. is a large-scale private enterprise and a key leading enterprise of agricultural industrialization. It has 24 production bases and spans industries such as edible oil, condiments and vegetable processing. The annual production capacity of edible oil is 1 million tons, and the annual production capacity of condiments is 100,000 tons.
ZOZEN boiler Technical Team has customized various models and parameters of thermal oil heater according to the actual conditions of Fuxin Oil Plant. The person in charge of the project said that a total of YQW-14000Q, two YQL-105000Q and one YQW-4200Q thermal oil heater have been installed in the boiler room of the Fuxin Oil Plant of Luhua Group. Their rated thermal power is 12 million kcal, 900,000 kcal, 3.6 million kcal, which meet the edible oil processing drying / cooling - hot air frying - suction cooling - rolling crushing / peeling - steaming and other cumbersome production processes.
