With a large flow of tourists, Zhengzhou Railway Station is one of the eight transportation hubs in China. It is known as the heart of Chinese railways. The comfortable waiting environment comes from stable heating system. It is Zhengzhou Heating Company Second Road Heat Source Factory that provides stable heat source for Zhengzhou Railway station. Founded in 1989, the heat source factory was put into operation in 1992. In recent years, with the aging of old boilers, the thermal efficiency of the existing 4 sets of 20 tph chain grate steam boilers has been gradually reduced. Besides, considering environmental protection and other factors, Second Road Heat Source Factory decided to implement the Coal-to-Gas Project, dismantle the existing low-efficiency and high-consumption coal-fired boilers, and introduce some sets of SZS series gas-fired steam boilers.
Founded in 1994, Harbin Investment Group Co., Ltd. is mainly engaged in production and supply of electricity and heat. The SZS series gas-fired package boiler purchased by public bidding performed well both in environmental protection and thermal efficiency. Adopting D-type arrangement and water tube structure, the boiler is equipped with a big combustion chamber for the full combustion of fuel. Advanced low NOx combustion technology is combined to reduce the
NOx emission to 30mg/Nm3. Combustion chamber is designed with narrow distance full membrane water cooling wall which has good air proof and high thermal efficiency. Meanwhile, the flue gas condensers equipped at the tail of the boiler can effectively control the flue gas temperature, increasing the thermal efficiency of the boiler to over 98%. Besides, the package delivery feature of SZS series gas-fired boiler greatly reduced infrastructure cost
For a long time, steam boilers have played an indispensable and important role in the production lines of various feed enterprises. Established in 1996, Guangdong Yuanxin Feed Industry Co., Ltd. is a company integrating R & D, production and sales of livestock, poultry, aquatic products and bullfrog feed. With the rapid development in recent years, the market share of Yuanxin Feed has continued to expand, and the company needed to purchase new steam boilers to meet the actual needs of the production line. Based on the mutual understanding and trust, Yuanxin Feed purchased boiler equipment again from ZOZEN on the SZL series chain grate steam boiler.
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
Industrial boilers provide a stable steam heat source for the drying, rolling, and vulcanization of tire processing. ZOZEN has reached cooperation with many rubber products manufacturers with high quality products. Sichuan Haida Rubber Group Co., Ltd. is an enterprise integrating R&D, operation and production of automobile tires, products include all-steel commercial radial tires, semi-steel passenger radial tires and oblique commercial tires.
Under the general trend of global economic green development, biomass-fired boilers use biomass-forming pellets such as crop straws and forestry residues as fuel have become the choice of many enterprises because of their environmental protection advantages. Among them, Hunan Leading Construction Technology Co., LTD., specializing in the R&D, production and sales of lightweight building materials, is an integrated supplier of various advanced application technologies. In the production process of high-precision aerated concrete blocks and plates, ZOZEN SZL series biomass-fired boilers provide a stable heat source for the autoclave curing process.
Hebei Anguo Modern Traditional Chinese Medicine Industrial Park takes modern Chinese medicine and healthy food as the leading industriies. The industrial clustering advantages and perfect infrastructure conditions have attracted many enterprises such as Tong Ren Tang, Tasly and China National Traditional Chinese Medicine Co., LTD. The concentrated supply of high-quality steam provides sufficient heat for the drying, extraction and stewing of traditional Chinese medicines. Therefore, these enterprises have strict requirements on the performance in various aspects of steam boilers.
Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.
