ZOZEN Coal-fired Steam Boiler Helps PT.WIRAJAYA PACKINDO in Indonesia Meet Its High Demand for Steam
PT.WIRAJAYA PACKINDO, a leading pulp and paper mill in Indonesia, required a reliable and efficient source of steam to support its production process. The preheating, cooking, and drying of raw materials and paper required a significant amount of steam, making the selection of the right boiler critical for the mill’s operations.
After thorough research, PT.WIRAJAYA PACKIND...
Dongguan Meizhe Plastic Products Co., Ltd., also known as Meijer International Co., Ltd., is a professional PVC flooring manufacturer. By virtue of the advanced R&D technology, automatic production equipment and abundant quality management experience, the PVC flooring produced by Meijer International is sold well in Europe, the United States, Japan and other countries for its high quality, safety and no harm for health. It adopts natural marble powders to form a solid base layer with a high-density and high-fiber network structure. Its surface is covered with super abrasion-resistant polymer PVC layers. Its production undergoes hundreds of processes, among which the shaping, filming and other processes need sufficient heat supply, so industrial boilers are important equipment on the PVC flooring production line of Meijer International.
The new process using the ethylene oxide method has low production costs and stable product quality, however, the yield of the ammonification process and the production continuity are the key points in the process. Therefore, Jiangyin Huachang Food Additive Co., Ltd. has set clearly high requirements for the entire boiler system. ZOZEN Boiler tailor-made the design of the YQW+WNS series boiler system project in order to meet the sufficient and continuous heating source support of the food additive production line. Among them, the body of YQW series gas-fired thermal oil heater adopts three-pass round coiled tube structure, with sufficient heating surface, and the energy-saving device installed at the end of the furnace can ensure the thermal efficiency up to 95%. The advanced combustion device can realize low NOx emissions of the entire boiler system, meanwhile ZOZEN Boiler has equipped the automatic control system to ensure the continuous and efficient operation of the heating source
In order to meet its heating requirements in winter, Ainengju Photovoltaic introduced the ZOZEN DZL series biomass-fired boiler. Being aware of the importance of innovation and development, ZOZEN pays attention to the cultivation of talents and the construction of talent pools all the time. ZOZEN also actively reaches cooperation with universities and research institutes. ZOZEN DZL series biomass-fired boiler is longitudinal arrangement with a single drum. According to the characteristics and fuel rate of different biomass fuel, ZOZEN reasonably arranges the heating surface of the furnace arch, furnace wall and furnace chamber of the DZL series of boiler to ensure the overall thermal efficiency and the normal and stable operation of the boiler.
This time, Shanghai High-New Science & Technology Development Co., Ltd. selected the ZOZEN YQW series gas-fired thermal oil heater and supporting waste heat boiler for its project in Ethiopia. To ensure the hot-pressing quality of the wood-based panels, the temperature of the hot-pressing board surface should be as uniform as possible. Therefore, High-New Science & Technology set clear requirements that the oil temperature and operation of the thermal oil heater should be stable. This series of boiler adopts a waste heat boiler to recover high-temperature flue gas. The team generated through the heat exchanges of the waste heat boiler can heat the mill, rubber making machine and other facilities that require steam heat source. The waste heat boiler not only further improves the fuel utilization, but also improves the overall thermal efficiency of the heater to more than 95% and reduces the operation costs. In addition, many advanced facilities independently developed by ZOZEN provide a
As a well-known industrial boiler manufacturer, ZOZEN focuses on the research and development of energy-saving technology. In order to help Hongda Textile to reduce energy consumption, ZOZEN customized the WNS series gas-fired boiler system according to the actual requirements of its production lines. Through the application of several patent technologies, this series of boiler has truly realized energy saving and high efficiency in terms of combustion efficiency, exhaust gas temperature, etc. Equipped with an advanced burner, the WNS series boiler realizes reasonable air distribution. Meanwhile, the large-diameter corrugated furnace of ZOZEN WNS series gas-fired steam boiler not only increases the heating-transfer surface but also ensures the full combustion of fuel, which increases the efficiency and reduces the consumption of fuel. In addition, ZOZEN adopts the patented condensing technology, which can fully absorb the waste heat of the exhaust gas, improve the water inlet temperatu
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
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.
