From 2014, Baoji City began to implement natural gas projects and vigorously implemented coal-to-gas conversion projects. Baoji Cigarette Factory is one of the major backbone enterprises of the China National Tobacco Corporation and is the largest cigarette manufacturer in the northwest region. In line with the environmental protection policy, Baoji Cigarette Factory implemented the "coal to gas" project. Through bidding activities, it cooperated with ZOZEN boiler to dismantle 35 tons of coal-fired boilers and install 25 tons of SZS gas-fired steam boilers to improve boiler operation levels and reduce air pollutant emissions.
The "Golden Leaf Group" is one of the only listed companies in the country for tobacco. In 2010, Golden Leaf established a Good Cat Cigarette Company in Xian, which mainly produces high-grade cigarette pack printing and cigarette filter rods. Good cat companies need to use a lot of steam in combination with filter rod production, tobacco carton compounding, and drying. According to the requirements of the national environmental protection regulations, standards, environmental impact assessment technical guidelines and other requirements, the boiler was invited to bid. ZOZEN boiler had the honor to provide a 10 ton WNS condensing gas-fired steam boiler for production use. Vertical and circumferential seams of the boiler, ZOZEN are all using advanced submerged arc welding technology, and 100% ray detection to ensure the quality of welding. At the same time, the WNS series boilers are equipped with sufficient steam space and heating surface so that the boiler can efficiently produce high-
Jiangsu SINOPEC mainly produces power cables, fire-retardant cables for coal mines, and various flame-retardant and fire-resistant special wires and cables. Wires and cables project production process requires a lot of steam, in which the extruder heating, mixing rubber equipment preheating process in the drive 1 ~ 2h need to use 0.3 ~ 0.4MPa low pressure steam preheating, cable continuous cross-linking process requires a pressure of 2.5MPa Steam as a heating medium. In recent years, through years of sustained and stable development, the company’s scale and overall strength have been continuously improved. In 2016, Jiangsu SINOPC replaced coal-fired boilers with gas-fired boilers. ZOZEN and Jiangsu SINOPEC are both in the beautiful coast of Taihu Lake. As we all know, ZOZEN boiler has advanced manufacturing technology and complete equipment, the service life of the boiler is very long. After the inspection at ZOZEN boiler, Jiangsu SINOPEC ordered two 6-ton SZS condensing gas-fired boil
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.
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.
Sinopharm is a professional and high-growth pharmaceutical company that integrates R&D, production and marketing. It specializes in pharmaceutical chemistry, pharmaceutics, drug synthesis, drug analysis, pharmacology and biomedicine, and clinical fields. In the pharmaceutical industry, it is well-known that steam is one of the most important energy sources that pharmaceutical companies need to produce. Steam is used for heating, concentration, drying, heat exchange, and heating in production. Because of production needs, Sinopharm Co., Ltd. has purchased two 10-ton WNS series condensing gas-fired steam boilers from ZOZEN boiler and put them into production after installation and commissioning. This set of condensing gas-fired steam boiler can not only generate high-temperature saturated steam in the pharmaceutical process, but also can adjust the multi-range according to the demand for steam to meet the needs of different steam volumes in the pharmaceutical process.
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.
The thermal oil heater
The processing and production of agricultural and sideline products, which involves dehydration, drying, refrigeration, freezing, salting and other technical processes, they all need a large amount of steam. Usually, such food companies purchase high-efficiency high-pressure steam boilers. As a long-established brand enterprise that pioneers the “new era of peanut leisure”, its main business is: sapid peanuts, sesame oil, chili power and snack food. After a period of investigation and comparison, the principal of the company chose to purchase two sets of horizontal gas-fired thermal oil heater(7 million kcal) at ZOZEN, which according to calculate the amount of steam used in production and processing of the products. The boiler of ZOZEN utilizes the high-temperature characteristics of the thermal oil heater to support low-pressure and high-temperature heat, can use a closed or opened circulate system according to the needs of users.
